The compositions in this guide shall not be considered as chemical requirements for any particular product until adopted by the subcommittee overseeing that product.
5.6 Chromium— A co comp mpos ositi ition on sp spre read ad of 2 % is re reco commmended; existing broader limits were not reduced to less than a 3 % spread.
4.2 Assum Assuming ing that unifo uniform rm compositions compositions among the many product standards for stainless steel are desirable, the composition limits provided in this standard are to be used as guides in determining limits for each of the elements included in the total composition of each grade. The composition limits have been established with the intent that each product subcommittee will find it necessary to require only a minimum number of changes to reflect specific technical effects. Section 5 Section 5 lists the general guidelines followed for determining the limits for each element; the limits established in this guide are based on these guidelines.
5.7 Nickel— It It is recommended that the composition spread not exceed 3 % unless a broader (generally higher) spread is justified by specific technical effect. 5.8 Molybdenum— It It is recommended that the composition spread not exceed 1 %, unless a broader range is justified by specifi spe cificc tech technic nical al ef effec fect. t.

5.11 Columbium and Tantalum— Except Except for special applications requiring positive identification of tantalum, it is recommended that prior listings of these two elements together be limited to listing only columbium. The words “columbium” and “niobium” refer to the same element.
5.1 Carbon— It It is recommended that limits be to only two decimal places for levels of 0.04 % and higher because because it is not necessary to control to such precision at levels above 0.04 %. (It should be recognized that limits such as 0.045 % maximum may also be sim simpl ply y sta stated ted as 0. 0.04 04 % ma maxi ximu mum. m.)) It is als also o recommended that three decimal places be used at levels of 0.030 % and lower, unless, for example, it is clearly recognized that 0.03 % maximum means that 0.035 % is satisfactory.
