42 CrMo4V
42 CrMo4V
(OP)
We have an immediate need to obtain pricing and source a US equivalent that would meet ALL specs for 42 CrMo4V.
70mm round bar for bolt application
Yield point 750<s0.2<800 MPa - Elongation to fracture >12%
ISO - V impact test result at -40 deg C should be:
Average value over 3 samples >27J
Minimum value >70% of average value
Do you know of what US steel would meet the requirements? Is it 4140 or 4142 with Vanadium? Or is there another one?

RE: 42 CrMo4V
It seems that something close is Grade B16 according to ASTM A 193/A 193M Standard Specification for Alloy-Steel and Stainless Steel Bolting Materials for High-Temperature Service.
If you need a North American source for bars, then try Republic, MACSTEEL, or Mittal:
