CS80 Spring Steel
Introduction
CS80 is a spring steel grade within BS1449. It is the equivalent to C75S and AISI /SAE 1075, and closely matches EN42.
CS80 is usually supplied in the hardened and tempered condition.
It is widely used for the manufacture of flat springs, knives and blades. It has gained popularity in recent years, as whilst it was notoriously difficult to cut, the advent of laser and water jet cutting techniques have largely overcome this issue.
Our material is precision rolled with a good surface finish, close thickness tolerance and good flatness.
