13CrMo4-5 vs 42MnV7
Side-by-side chemical composition and mechanical property comparison.
Overview
13CrMo4-5
1.7335
Low-alloy Cr-Mo steel for elevated-temperature service. Good creep resistance up to 500°C. The standard grade for boiler tubes, headers, superheater tubes, and pressure equipment in power generation. Lower alloy content than 10CrMo9-10.
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.
