16MnCr5 vs 27MnCrB5-2: 43% composition overlap. Significantly different materials serving different application areas.
16MnCr5 vs 27MnCrB5-2
Side-by-side chemical composition and mechanical property comparison.
Overview
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.
27MnCrB5-2
1.7182
Manganese-chromium-boron steel for direct hardening and hot stamping. Boron addition (0.0008-0.005%) dramatically improves hardenability at low cost. The standard grade for automotive press-hardened body-in-white components (B-pillar, side impact beams, bumper reinforcements).
