17NiCrMo6-4 is low carbon case hardening steel which has at least 0.8Cr%,1.2%Ni and 0.15%Mo. It is the most common case hardening steel and has a medium-high hardenability and good machinability. After case hardening and hardening treatments, the surface reaches an elevated hardness.

All our forged 17NiCrMo6-4 material is melted in ultra-high power electric arc furnaces and then refined using advanced ladle metallurgy. Vacuum degassing and vacuum oxygen decarburization (VOD) processes assure optimum steel cleanliness,ESR that depends on clients needs,

Chemical composition of 17NiCrMo6-4 forging shafts is as following

Carbon 0.14 - 0.2 %
Chromium 0.8 - 1.1 %
Copper 0.4 %
Manganese 0.6 - 0.9 %
Molybdenum 0.15 - 0.25 %
Nickel 1.2 - 1.5 %
Phosphorus 0.03 %
Silicon 0.15 - 0.4 %
Sulfur 0.035 %
