Spring steel strip normally contains between 0.40% to 0.80% carbon, with alloy elements added for the higher integrity products such as automotive clutches etc.

General Applications: Spring steel strips are quite used in the production of springs, also used in a number of applications where hardness or resistance to bending is required, such as lock parts or tools.

Supply Condition: Hardened and tempered condition.

Hardened and tempered strip is more suitable for flat components or where the production is primarily laser cutting or plain blanking.
