Equivalent grade of steel to AS 2074 L6B-1
Equivalent grade of steel to AS 2074 L6B-1
(OP)
Hi
Is anyone aware of a similar ASTM / ISO specification for steel to Australian Standard AS 2074 Grade L6B-1? Is there even an old British standard equivalent to AS 2074?
Application is a drive lever that is likely to be flogged using sledge hammers, therefore the impact strength is important. The UTS of L6B-1 is 850 MPa with a yield of 590 MPa. Elongation is only 8%, hardness is 248 - 302 HBW (Brinnel). The material has worked well in the past so we are loathed to change but are looking to source overseas.
Cheers.

They have equivalent ASTM and UNS grades.
