C35 vs S690Q: 28% composition overlap. Significantly different materials serving different application areas.
C35 vs S690Q
Side-by-side chemical composition and mechanical property comparison.
Overview
C35
1.0501
Medium-carbon unalloyed steel with moderate strength. Good machinability and weldability. Used for lightly stressed components like levers, axles, bolts, and general machine parts.
S690Q
1.8928
High-strength quenched and tempered structural steel — YS 690 MPa min. Part of EN 10025-6 series (S500Q to S960Q). Good weldability despite high strength (CEV controlled). Used for mobile cranes, mining equipment, truck chassis, bridge components, and any structure where weight reduction through higher strength is critical. "Q" = quenched, "L" variants add low-temp impact.
