1075 스프링 강판 스트립
1075 spring steel is equivalent to C75S, usually supplied in hardened and tempered condition and widely used for the manufacture of springs, washers, lock picks, saw blades.
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. Spring steels 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.
Spring steels are supplied in either annealed condition or hardened and tempered condition. Steel supplied in the annealed condition is usually hardened after the stamping and forming operation in component form. Hardened and tempered strip is more suitable for flat components or where the production is primarily laser cutting or plain blanking.
