Typical UTS Yield: UTS = 430 Yield= 340 Colour Code: Orange - Metric Red - Imperial

Characteristics: Bright ree cutting bar is available in round, square and hexagonal sections and gives the same beneits as bright commercial quality in terms o good sectional tolerance, straightness and increased physical properties. The major beneit is rom the combination o manganese and sulphur in the steel. These elements orm manganese sulphide inclusions which eectively act as ‘chip breakers’ during machining and allow this grade to be machined at much higher speeds with no adverse eect on tool lie. Can be welded using specialised procedures and electrodes.

Applications: Manuacturing applications where extensive machining is involved, i.e., nuts, bolts, studs, etc. or any other application involving high speed automatic machining operations.

Medium Tensile Steel:> Medium Tensile Steel AISI 1040/45 Heat Treatment Procedures:

AISI 1040 is available in either cold drawn or hot rolled condition. The cold inishing process o ‘drawing’ does slightly improve the mechanical properties over those o a hot rolled bar. However, thermal treatments must be employed i higher mechanical properties are required. AISI 1040 is suitable or surace hardening by lame or induction methods. Hardness and tensile strength may also be urther increased by conventional quenching and tempering though the results are somewhat sensitive to the materials section size (see tempering diagrams).

Cool slowly in urnace at not more than 65 OC/hr. Air cool. Holding time in urnace should be 10mins/cm o ruling section ollowed by oil or water quenching. Temperature depends on required hardness (see tempering diagrams). Tempering should be carried out ‘immediately’ ater quenching. The tempering time being at least 1 hour per 25mm o section. Heating should be rapid in order to localise the heating eect to the surace o the bar. Quench immediately into oil or water. Temper immediately at 150-200OC or maximum surace hardness. Surace hardness obtainable 56-60 HRC.

Heat Treatment Procedures:

Although AISI 4140 is supplied in the already heat treated condition at a tensile strength o 850-1000MPa, there will inevitably be certain applications where a higher strength is required or where a higher surace hardness is needed to withstand abrasion. The ollowing recommendations are intended as a guide to urther thermal treatments. Note: Beore any urther ‘through hardening’ treatments are carried out the material should irst be annealed.

Black condition Material is produced under consideration o the common machining allowances indicated in DIN 17350, part 10 (drat 6/83). When manuacturing tools suicient allowance must be made or machining to remove scale which originated during orging, rolling and annealing as well as decarburization and sometimes surace imperections.

Premachined Tool Steels Premachined tool steels oer to the user a smooth surace with machining allowances already strongly narrowed down. The advantages o a premachined surace can be seen rom the diagram shown on page 91. Depending on size 7 to 10% o the weight can be saved.

Cold Work Tool Steels:>


Cold Work Tool Steels:> Recommended Steels or Blanking Dies and Punches:

The Blanking Clearance: To prevent the piece to be manuactured being upset, and to keep the riction low during the cutting operation, the opening o the cutting plate has to be somewhat larger than the cross-section o the cutting punch. The distance between the cutting edges o the plate and the punch is designated as blanking clearance. Its size is dependent on the properties and the thickness o the sheet to be cut as well as on the blanking procedure. The narrower the blanking clearance, the smoother is the cut surace. With the blanking clearance being too small, the power required largely rises because o the increased riction and the upsetting o the material to be processed. This may lead to premature blunt edges or to chipping o the cutting edges. A blanking clearance that is too large is disadvantageous as well, since the material to be cut may be pressed into the gaps resulting in heavy explosive stresses which may cause a premature rupture o the cutting plates. In the diagram reerence data or the blanking clearance as a unction o the sheet thickness are indicated or conventional and precision blankings. When blanking sot materials the blanking clearance should range at the lower limit o the respective scattering zone, whereas it should be at the upper limit when blanking materials with a higher strength.

Blanking Dies: Blanking dies cut the material by a shearing eect. Cutting edges o a deinite shape move along side by side separating the material. The design o a blanking die is mainly dependent on the required accuracy and number o the pieces to be cut as well as on its type and grade. For illustrating the tool design a guide blanking die column type is represented in the diagram. In the blanking procedure only about one third o the sheet thickness is cut, whereas the residual thickness breaks away due to the tensile stresses. Dependent on the sheet thickness, steel grade and strength as well as the size o the blanking clearance a more or less harp burr generates which usually requires a remachining o the cut edge.

Standard blanking die in comparison with precision blanking die standard blanking die

Essentially more precise edges may be attained with precision blanking dies. They require, o course, precise tool guides very irmly built, since the clearance between the cutting punch and the die must be kept very low. Precision blanking dies necessitate a hold-down ixture or a pressing plate itted with annular teeth, particularly in the case o greater sheet thicknesses. Moreover, a counterpressure punch simultaneously perorming the unction o the ejector pin will be necessary. Tensile stresses in the blanking clearance are avoided by this tool design and the sheet is sheared throughout the entire thickness. Precision blanking die components have right-angled smooth cutting edges and are distinguished by an excellent planeness.

Plastic Mould Steels:>


Plastic Mould Steels:> Increasing demands with regard to the tools in plastic moulding ask or the speciic development o tool steels having certain service properties or dierent ranges o application. Tools or the processing o plastics are mainly stressed with regard to pressure and wear. According to the type o plastics, there may in addition exist a stressing by corrosion. The various types o plastics and dierent processing methods set requirements on the tool steel, as or instance: •Economicmachinabilityorcold-hobbingability •Smallestchangeinsizeuponheattreatment •Goodpolishability •Greatcompressivestrength •Highwearresistance •Sufficientcorrosion-resistingquality The selection o a steel or a given tool is governed by these requirements. The current tool steels or plastic moulding are indicated in the list below. These steels meet nearly all requirements.

Steel Selection: Case hardening steels: Apart rom a proper design and a heat treatment adapted to the respective steel grade the selection o a suitable steel is decisive or the eiciency o a tool. The case hardening steels oer excellent polishability and machinability. Thereore injection moulds as well as compression moulds are chiely made rom polishable case-hardening steels possessing high wear-resistance in the carburized case combined with good toughness in the core.

Nitriding steels 1.8550

Maraging steels 1.2709


Plastic Mould Steels:> Heat-treated steels: Even with large sizes, suicient core hardness can still be achieved. With the plastic parts becoming larger and larger, the use o case-hardening steels makes the heat treatment o the moulds a diicult problem because o the dimensional changes involved. Moreover, the number o articles to be made being requently small, the production capacity o such moulds is not ully utilized. Hence, one proceeded to cut the impression into a previously heat-treated block by a machining operation. Even smaller sized moulds are now made by this method. A working strength o about 1100 N/mm 2 has been ound to give the best results. As heat-treated steels and grades 2311, 2312 and 2711 have been developed. 2311 and 2711 are preerably used in cases o high demand or polishability and or moulds with textured suraces. 2312 is produced with increased S-content thus oering an excellent machinability combined with good polishability.

Plastic Mould Steels:> Nitriding steels: Nitriding steels are successully used or screws and cylinders, since they have a tough core and a hard wear-resistant surace. The aluminium-alloyed-nitriding steel 1.8850 presents a very high surace hardness.

Corrosion-resistant steels: 1.2083, a corrosion-resistant 13% chromium steel, is used or processing chemically active plastic materials.

Through-hardening steels: Through-hardening steels are distinguished by high hardenability and compressive strength. Moreover, they are characterized by a superior close tolerance upon heat treatment. Due to their high compressive strength they are best suited or plastic moulds being subjected to high compressive orces. A signiicant advantage or these steels is given by the possibility o carrying out greater machining operations ater the heat treatment. Contrary to the case hardening steels in this case there is no risk o wearing out a carburized surace zone resulting in a new heat treatment. The tool steel 1.2767 oers high toughness and is used or adequately stressed moulds. Moreover this steel oers a good polishability, ability or photo etching and eroding. Especially during heat treatment in vacuum urnaces it is distinguished by lowest size changes. 1.2344 EFS is especially suitable or moulds and screws as it can be nitrided and still have a high core strength ater nitriding. Due to its high hot tensile strength also moulds and screws being subjected to a higher thermal load are successully manuactured rom this steel. The grades 1.2379 and 1.2842 listed among the group o through-hardening steels are predominantly used or pressure pads and smaller-sized plastic moulds when processing duroplastics o an abrasive nature.

2767 EFS Supra: Where there is an extremely high requirement o polishability, ability or photo-etching and eroding, remelted tool steel is recommended. Thereore, the grade. 1.2767 EFS SUPRA has been developed or mirror-polished plastic moulds, or inest photo design and or texture-eroded suraces. The dimensional stability during heat treatment was urther improved compared with the standard grade.

A) The tolerances above are based on the ollowing method o measuring straightness; departure rom straightness is measured by placing the bar on a level table so that the arc or departure rom straightness is horizontal and the depth o the arc is measured with a eeler gauge and a straightedge. B) It should be recognised that straightness is a perishable quality and may be altered by mishandling. The preservation o straightness in cold-inished bars required the utmost care in subsequent handling. Speciic straightness tolerances are sometimes required or carbon and alloy steels in which case the purchaser should inorm the manuacturer o the straightness tolerances and the methods to be used in checking the straightness. C) For centreless ground bars, the maximum deviation straightness shall be less than 0.30mm over 1 metre.
