Yield Point s0.2 MPa
Yield Point s0.2 MPa
(OP)
Hello, we are quoting a steel part that is material 42 CrMo4V or equivalent.
The spec calls for a Yield Point 750<s0.2<800 MPa.
Can you me understand in US terms what the Yield point and the numbers after it mean?
thank you

RE: Yield Point s0.2 MPa
Yes. The yield point is derived from a standard tensile test of the subject steel. It is the value, expressed in tensile stress (force/area) where the material will permanently deform by 0.2% elongation. It would appear that the yield point is being expressed within a range of 750-800 MPa.
You can convert the MPa into Psi
750 MPa ~ 108,788 Psi
800 MPa ~ 116,030 Psi
RE: Yield Point s0.2 MPa
Are you familiar with a US equivalent that would meet these specs for 42 CrMo4V?
70mm +.2 - .4 (2.756 + .008 - .016) diameter Turned and polished
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
