A

Unless otherwise indicated, a grade designation originally assigned by the American Iron and Steel Institute (AISI). Yield strength shall be determined by the offset method at 0.2% in accordance with Test Methods and Definitions A 370. Unless otherwise specified (see Specification A 480/A 480M, paragraph 4.1.11, Ordering Information), an alternative method of determining yield strength may be based on total extension under load of 0.5%. C Either Brinell or Rockwell B Hardness is permissible. D Bend test are not required for chromium steels (ferritic or martensitic) thicker than 1 in. [25 mm] or for any austenitic or duplex (austenitic-ferritic) stainless steels regardless of thickness. E Elongation for thickness, less than 0.015 in. (0.38 mm) shall be 20% minimum, in 1 in. (25.4 mm). F Common name, not a trademark, widely used, not associated with any one producer. G Yield strength requirements shall not apply to material under 0.020 in. (0.50 mm) in thickness. H Not applicable for thickness under 0.010 in. (0.25 mm). I Type 201 is generally produced with a chemical composition balanced for rich side (Type 201-1) or lean side (Type 201-2) austenite stability depending on the properties required for specific applications. J Rockwell C scale. K For S32615, the grain size as determined in accordance with the Test Methods E 112, Comparison Method, Plate II, shall be No. 3 or finer. L Naming system developed and applied by ASTM. M Prior to Specification A 240–89b, the tensile value for S32950 was 90 ksi. N S40900 (Type 409) has been replaced by S40910, S40920, and S40930. Unless otherwise specified in the ordering information, an order specifying S40900 or Type 409 shall be satisfied by any one of S40910, S40920, or S40930 at the option of the seller. Material meeting the requirements of S40910, S40920, or S40930, may at the option of the manufacturer be certified as S40900. O Material 0.050 in (1.27 mm) and under in thickness shall have a minimum elongation of 20%. B

SUPPLEMENTARY REQUIREMENTS A supplementary requirement shall apply only when specified in the purchase order.

on duplex stainless steels covered in both Specification A 240 and Test Methods A 923 to be performed at the lower of the temperatures specified by this supplementary requirement and Test Methods A 923 Method B, with measurement of both lateral expansion and impact energy.

S1. Charpy Impact Testing of Plate S1.1 Charpy impact tests shall be conducted in accordance with Test Methods and Definitions A 370. S1.2 Number of Tests — One impact test (3 specimens) shall be made from one plate per heat treatment lot in the final heat treated condition.

S1.5 Acceptance Limit — Unless otherwise specified on the purchase order, each of the three specimens tested shall show a lateral expansion opposite the notch of not less than 0.015 in. [0.38 mm].

S1.3 Orientation of Test Specimens — Unless specified as transverse specimens (long axis of the specimen transverse to the final rolling direction, root of the notch perpendicular to the rolling face) on the purchase order, the orientation of the specimens shall be longitudinal (long axis of the specimen parallel to the final rolling direction, root of the notch perpendicular to the rolling face). The manufacturer is permitted to test transverse specimens provided that such tests meet the acceptance criteria applicable to longitudinal specimens. Unless otherwise specified on the purchase order, the specimens shall be taken so as to include the mid-thickness of the product.

S1.6 Records — The recorded results shall include the specimen orientation, specimen size, test temperature, absorbed energy values (if required), and lateral expansion opposite the notch.

S2.

Materials for High-Temperature Service

S2.1 Unless an H grade has been ordered, this supplementary requirement shall be specified for ASME Code applications for service above 1000°F [540°C].

S1.4 Test Temperature — The purchaser shall specify the test temperature. The manufacturer is permitted to test specimens at a temperature lower than that specified by the purchaser, provided that such tests shall meet the acceptance criteria applicable to specimens tested at the specified temperature (see Note).

S2.2 The user is permitted to use an austenitic stainless steel as the corresponding H grade when the material meets all requirements of the H grade including chemistry, annealing temperature, and grain size (see Section 6). S2.3 The user is permitted to use an L grade austenitic stainless steel for service above 1000°F [540°C], subject to the applicable allowable stress table of the ASME Code, when the material meets all requirements of this specification and the grain size is ASTM No. 7 or coarser as determined in accordance with Test Method E 112. The grain size shall be reported on a Certified Test Report.

NOTE — Test Methods A 923, Method B, applicable to some duplex (austenitic-ferritic) stainless steels as listed in Test Methods A 923, uses a Charpy impact test for the purpose of determining the absence of detrimental intermetallic phases. Method B specifies a test temperature and acceptance criterion, expressed as impact energy, for each type of steelcovered. It may be economical for the Charpy impact tests performed

SUMMARY OF CHANGES

(2) Added new alloy UNS S31277 to Tables 1 and 2. (3) Added UNS S32906 to Tables 1 and 2. (4) Added UNS S32101 to Tables 1 and 2. (5) Added a new duplex stainless steel (S32003) to Tables 1 and 2.

The Committee has highlighted those changes that impact the use of this specification. This section may also include descriptions of changes or reasons for changes, or both. (1) In Table 2, HBN and HRB for S20100, S30451, and S30453, were reconciled with those in Specification A 666, annealed condition. ` ` , , , , ` ` ` , , ` ` , ` ` ` , , , ` , ` , ` , ` ` , ` ` , , ` , , ` , ` , , ` -
