RE: [MW:25307] Difference between Cr content range in casting and forge SS316

Castings are manufactured by “Melting & pouring “Technique. Alloy losses are more in during casting; hence the compositional range is wider.

Materials chosen for forging already will have some preset compositions, not the same as casting where the composition is to be finalized, when the liquid metal is to be poured. Hence the range could be narrower.

 

Thanks.

Would you please for the reason?

not only Cr is higher but also Ni is lower.

Dear Experts
Good day!!!

I'll highly appreciated if you share your valuable ideas regarding reason for difference between Cr content range in A351 CF8M and A182F316 which is 18-21% and 16-18% respectively.

Regards,
H.Nikdin
