Mr. Schwartz:
ASME SA-516 Gr
70
Cheneistry:

Mechanical
Properties:
Tensile Strength = 70/90 Ksi
Yield Strength = 38 Ksi
Elongation in 8" = 17%
Elongation in 2" = 21%
Typical Rockwell hardness prior to any hardening = 85 HRB (163 Brinell),
could reach 45HRC (430 Brinell)
recommendations:
ASME SA-516 Gr 70 Vs. 316L St. Steel
516-70 have higher yield strength than 316L (38Ksi to
34Ksi)
516-70 have lower elongation percentage (Higher Toughness) than 316L (21% to
55%)
516-70 will always yield to a higher hardness and toughness due to Cr, Mo, and V
carbides when annealed.
