10CrMo9-10 vs 42MnV7
Side-by-side chemical composition and mechanical property comparison.
Overview
10CrMo9-10
1.7380
Low-carbon Cr-Mo steel for elevated temperature pressure equipment. Excellent creep resistance up to 530°C. The standard grade for boiler tubes, headers, and pressure vessels in power generation and petrochemical industries.
42MnV7
1.5223
Vanadium-microalloyed medium-carbon steel for controlled-cooling after forging — achieves target properties without separate Q&T heat treatment ("as-forged" concept). V precipitates (VN, VC) give precipitation strengthening during air cooling. THE modern automotive crankshaft steel — replaces 42CrMo4 Q&T at lower total cost (no heat treatment furnace needed). Also used for connecting rods and large forged parts.
