14NiCr14 vs 17CrNiMo6
Side-by-side chemical composition and mechanical property comparison.
Overview
14NiCr14
1.5752
High-Ni case hardening steel — Ni 3.0-3.5%, Cr 0.6-0.9%, no Mo. Ni gives excellent core toughness at low temperature — used for case-hardened parts operating in cold environments. THE classic aerospace/defense case-hardening steel (BS S130/S131). Used for aircraft gears, military vehicle transmission gears, and cryogenic case-hardened components.
17CrNiMo6
1.6587
Premium CrNiMo case hardening steel for demanding gear applications. Ni 1.2-1.5% + Mo 0.25-0.35% give excellent core toughness and deep hardenability — suitable for large gears up to 400mm ruling section. Surface HRC 60-63 after carburizing. THE wind turbine gearbox steel. Also used for large industrial gearboxes, mining equipment, and heavy truck transmissions.
