C15E vs S500MC
Side-by-side chemical composition and mechanical property comparison.
Overview
C15E
1.1141
Low-carbon unalloyed case hardening steel — 0.12-0.18% C. Between C10E (softer core) and C22E (harder core) in the case-hardening range. Good balance of surface hardness (HRC 58-62) and core toughness after carburizing. Modern designation for Ck15. Used for small gears, pins, bushings, levers, and carburized parts where moderate core strength is acceptable. Also used for cold forming and deep drawing.
S500MC
1.0984
High-strength low-alloy (HSLA) hot-rolled steel for cold forming. Thermomechanically rolled for fine grain structure. 500 MPa yield strength with excellent cold formability. Used for automotive chassis, truck frames, crane booms, and agricultural equipment.
