DESCRIPTION: Hardened and Tempered Steel Strip (also known as hardened and tempered High carbon steel strip or, hardened and tempered carbon spring steel strip) is the basic raw material from which many different components are made, substantially being spring-type applications ranging from clutch plate segments to washers, retractor springs and even to tree springs in riding saddles and traditional clock springs.
APPLICATIONS: Band saw blades for wood working, Hand saw, Cross cut saw for wood cutting, Flat springs for automobile clutch plates, Doctor blades for paper industry, Shims and washers for automotive industries, Circular saw blanks, Engineering industry, Masonry and agricultural tools, Industrial knives, Stone cutting, Springs etc.
