Hardened and Tempered High Carbon Steel Strip

As one of the few suppliers in China for high carbon steel strips, we focus on high dimensional accuracy and excellent surface quality. We utilize the latest automated steelmaking systems and advanced technologies to process cold rolling and annealing to supply high carbon steel AISI/SAE 1045, 1050, 1055, 1060, 1070, 1074, 1075, 1080, 1085, 1090, 1095 strip coils.

The strength, durability and flexibility of high carbon steel make it suitable for many high strength applications. The particular AISI/SAE high carbon steel strips we supply are used by diverse industries in the manufacture of products such as saw blades, power springs, chainsaws, automotive parts.

• Thickness Tolerance (mm)

Several different grades of thickness allowance― A(standard) and S, SS, and SSS(special)― are available. The thickness is
measured arbitrarily at more than 10 mm from the edge of the steel. When the width is 20 mm or less, the steel is measured in the center portion.
