注：For small diameter or thin walls. or both, where many drawing passes are required, a carbon maximum of 0.040 % is necessary in Grades TP316L. Small outside diameter tubes are defined as those less than 0.500 inch [12.7 mm] in outside diameter and light wall are those less than 0.049 inch [1.2 mm] in minimum wall thickness. 碳當量計算

注：Quenched in water or rapidly cooled by other methods, at a rate sufficient to prevent reprecipitation of chromium carbides, as demonstrated by the capability of passing Practices A262, Practice E. The manufacturer is not required to run the test unless it is specified on the purchase order (See Supplementary Requirement S6). Note that Practices A262 requires the test to be performed on sensitized specimens in the low carbon and stabilized types and on specimens representative of the as-shipped condition of the other types. In the case of low-carbon types containing 3 % or more molybdenum, the applicability of the sensitizing treatment prior to testing shall be a matter for negotiation between the seller and purchaser.
