SKS51 Hardened and Tempered Carbon Steel Strip

SKS51 is a high carbon steel with about 0.80% carbon, to which Nickel and Chromium are added to increase toughness. Hardened and tempered strip steel is our original and actual core business. Baomit’s production team properly harden and temper carbon steel strips to satisfy the most demanding specifications of our customers. The particular AISI/SAE high carbon steels we offer are used by the automotive, blade, and aerospace industries, for example, and in the manufacture of products like blades, power springs, saws, automotive parts, washers, and more.
