13CrMo4-5 vs 60SiCr7
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.
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.
