9SMn28 high T data

[johanzp]

Hello,

anybody out there that knows the properties of a 9SMn28 (cutting) steel up to T=500C?

- Yield stress
- Tensile strength
- Elongation after fracture
- Young´s Modulus
- Thermal expansion
- Thermal conductance
- Specific heat capacity

Of course for the thermomechanical data will not be very different from other grades but Rp, Rm, A5 will be of great value. As this is by no means a typical high-T steel I have not found any creep data.

Similar data for comparable cutting steels will also be useful

thanks in advance

Johan,
saarstahl.com has some mechanical data on this grade.

It's also similar to SAE 1213.
