A Unless otherwise indicated,a grade designation originally assigned by the American Iron and Steel Institute(AISI).
B Yield Strength shall be determined by the offset method at 0.2% in accordance with Test Dethods and Definitions A370 .Unless otherwise specified (see Specification A480/A480M,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 tests 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.
*Note:This grade is non-magnetic in annealed condition but become slightly magnetic after cold working.
