SAE-AISI 1070 (C70, 1.1520, G10700) Carbon Steel

ALLOY TOOL STEEL FOR COLD WORKING 80CRV2, 1.2235 ACCORDING TO DIN 17350, UNE 36018, EN 10132-4.

Steel C100S，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。

C75S material is EN EN 10132-4 (2000) Cold rolled narrow steel strip for heat treatment

C67S steel is non-weldable, prone to decarburization and oxidation during heat treatment, and is not resistant to atmospheric corrosion.

C60 steel is an unalloyed medium carbon engineering steel which has 0.57%-0.65% Carbon as per EN10083 standard.

C55S is a medium carbon steel suitable for various type of applications where high strength is needed.

51CrV4 is a high strength quench and tempering steel suitable for quenched and tempered springs.

5160 are more responsive to heat and mechanical treatments than carbon steels.
