ASTM A311 (Stressproof) Material
ASTM A311 (Stressproof) Material
(OP)
Hi All,
I am looking for a near equivalent material for the ASTM A311. The most important, desired properties are the following:
1) Hardness: 241-293 HB
2) Yield strength: Min 690 MPa (100,000 psi)
3) Tensile strength (UTS): Min 795 MPa (115,000 psi)
4) Elongation: Min 7%
5) Reduction of area: Min 20%
Thanks in advance.

There are a ton of way to reach those properties, but the fatigue results may be very different depending on HT.

Bar diameter? That influences the selection.
Do you plan to weld? Case harden?
8620 is versatile and should meet the mechanical properties.

1144 should be called ‘weldproof’

Be careful - many steel suppliers will quote plain 1144 (not actually Stressproof).

With that said, I have been using 1144 round to make T-handle wrenches for myself and friends. I join the T with silicon bronze brazing alloy. They are quite strong.
I buy it from McMaster-Carr. Theirs claims to meet ASTM A311
