16NiCr4 Alloy steel 1.5714 material
Description
16NiCr4 Alloy steel is a low carbon case hardening steel which has at least 0.6Cr%,0.8%Ni as strengthening elements. It has a low-medium hardenability with good core resistance up to a thickness of about 50 mm, and had good machinability in the annealed condition.16NiCr4 is generally supplied in the annealed condition with Max hardness 217HB.
