17CrNiMo6 | DIN 1.6587 Case Hardening Steel-DIN 17210
As low carbon case hardened steel in DIN 17210,17CrNiMo6 steel contains 1.5-1.8% chromium,1.4-1.7% nickel and 0.25-0.35% molybdenum which give this steel grade excellent mechanical properties and application potential.
After carburizing, quenching and tempering heat treatment,17CrNiMo6 steel has excellent strength and hardness, as well as excellent wear resistance and good corrosion resistance
In the automotive industry, 17CrNiMo6 is used for the manufacture of parts such as gears, reducers and connecting rods; in the aerospace field, it is used for the manufacture of engine parts and aviation gears; in the machinery manufacturing field, it is used for the manufacture of bearings and gearboxes for large mechanical equipment.
