    Hadfield steel

    Hello, I have a chain consists of weld joint of hadfield steel and Cr-Mo-Ni steel. I would like to carburize this material (900-920°C). Next process will be a quenching (840 - 860°C/water) and a tempering (180-200°C). What do you think, is it possible to do it without cracks or lowering the...
