Blue Tempered Spring Steel Strip and Sheet
Spring steel normally contain between 0.40% to 0.80% carbon, with alloy elements added for the higher integrity products such as automotive clutches etc.
Steel Grades: 75Ni8, 1075, 1095, 75Cr1, 51CrV4, SK4, SK5, SK85
Surface Finish: blue polished, white polished, bright polished.
General Applications: 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.
Different values can be discussed with our technicians that will help customers to get better results in their production. Please send your custom request to sales@cableparts.net.
