dear all thanks for your answers. is cheaper in comparison with hot-working steels. and in our factory wee need to produce our die on ourselves in our factory which is not high-tech. any way, machniability,weldability, surface hardening, fatigue resistanc, wear resistance, low cost, good heat...
at the first, thanks for your response.
this material (4140) is used as die in which shell sands are shoot to produce core. so, the sand particles erode the die's wall. accordingly, i want to make the die's surface as wear-resistant. to do so,I think i should use carbonizing to harden the die's...
hi, dear all, i read all your conversation about 4140 steel heat treatment and properties.
here i have a question. it would be appreciated, if somebody answers that?
i have a mold made out of 4140 fr shell sand molding but i want to harden its surface. can you please give me the exact cycle...
