Re: [MW:13164] Induction hardening

I was working in an auto mobile gear work shop where we use to do Induction hardening of a shaft type part which was followed by tempering process to reduce the hardness level.

It was between 450 to 650 deg. centigrate for two hrs.

Thanks &  Regards

Hi
I am working for a fabrication company in South Africa. We have BS970: 709M40 (EN19) material 140mm in diameter, 230mm wide. We have done induction hardening and the client specification requires 350HB, +/-20HB. After the hardening was done we have an average of 430HB, how can we reduce this back to the required value of 370HB, please advice.
