Preventing Oxidation and Decarburization
Question: Can I prevent oxidation and decarburization during hardening of 1055 steel at 860C with super-heated steam at 550C using pretreatments?
Question:
Can I prevent oxidation and decarburization during hardening of 1055 steel at 860C with super-heated steam at 550C using pretreatments? Any better suggestions? M.Z.
Answer:
There are no economical pretreatments that would survive this temperature. Proper hardening of steels should be done in an inert atmosphere in order to avoid both oxidation and decarburization. An appropriate inert atmosphere would be nitrogen or argon.
