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.
60SiCr7
1.7108
Silicon-chromium valve spring steel — the highest fatigue life among EN 10089 spring steels. High Si (1.50-1.80%) provides excellent resistance to relaxation at elevated temperatures (up to ~250°C). Superior to 51CrV4 for high-stress, high-cycle applications. Used for automotive valve springs, heavy-duty coil springs, torsion bars, and stabilizers. ≈ AISI 9260.
