Steel C100S (1.1274) - specification and application

Low-alloy carbon steel for thermal improvement by oil hardening available in strips and thin cold-rolled sheets used for springs and leaf springs with small cross-sections. It is characterized by low hardenability, abrasion resistance and decarburization and oxidation tendency during heat treatment.

C100S steel products and its equivalents do not show resistance to atmospheric corrosion, and after heat treatment get tempered martensite structure. Carbon spring steels are delivered in various hardening and soft condition variants.

Steel used for spring washers, spring elements, feeler gauges, and other loaded parts requiring high elasticity and tensile strength.
