15CrNi6 | DIN 1.5919 Quality Case Hardening Steel
As case hardened steel in DIN 17210,15CrNi6 steel contains 0.14-0.19% carbon, 1.4-1.7% chromium and 1.4-1.7% nickel.
15CrNi6 steel has good mechanical property for highly strained parts and good toughness at core tensile strength of 900 – 1200 N/mm².
This materail is generally used driving bevel gears, crown wheels, gears, shafts, bolts for automotive and gear components.
