ASTM A276/A276M:2017 S31640 Steel: Specifications & Listings

Condition	Finish	Diameter or thickness, in. [mm]	Tensile strength, min (MPa)	Yield strength, min (MPa)	Elongation, min (%)	Reduction of area, min (%)	Brinell HBW, max
A (Annealed)	hot-finished	all	515	205	40	50	-
A (Annealed)	cold-finished	up to 1/2 [12.70] incl	620	310	30	40	-
A (Annealed)	cold-finished	over 1/2 [12.70]	515	205	30	40	-

Yield by the 0.2 percent offset method. Hardness is HBW unless otherwise indicated; equivalent Rockwell is permitted. For shapes of section thickness 1/2 in. [12.5 mm] or less, 30 percent elongation is acceptable. For extruded shapes of Cr-Ni grades in Condition A, yield 170 MPa and tensile 480 MPa minimum apply.
