C15E vs S460NL
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.
S460NL
1.8903
High-strength normalized fine-grain structural steel with 460 MPa yield and impact testing at -50°C. The highest-strength grade in the EN 10025-3 normalized series. Used for offshore platforms, wind turbine towers, arctic bridges, cranes, and heavy steel structures in cold climates.
