C85S, CK85, 1.1269, Spring Steel Strip

 

C85S, 1.1269, AISI 1086, CK85 is non-alloyed carbon structural steel with low hardening capacity for oil hardening for low-duty, periodically operating springs, springs and spring elements, immune to the temper brittleness. It is characterized by its high hardness and abrasion resistance, while maintaining high strength. It is used for flat and spiral springs, machine parts or saws of all kinds for cutting.
