Side-by-side chemical composition and mechanical property comparison.
Overview
100Cr6
1.3505
High-carbon chromium bearing steel. The most widely used bearing steel worldwide. Extremely high hardness and wear resistance after heat treatment. Standard for ball and roller bearings, precision shafts, and measuring instruments.
16MnCr5
1.7131
Low-carbon case-hardening steel with manganese and chromium. Excellent for carburizing to produce a hard, wear-resistant surface with a tough core. Standard choice for gears, camshafts, piston pins, and transmission components.
