Hardening strip steel, TBS band saw

Hardening strip steel

Our hardening strips are in the top class ranking in quality as well as quantity in the Steel Industry. We are giving various heat-treatment to strip of carbon tool steel, alloy steel, stainless steel and so on. And we are giving the mechanical properies most suitable for the material. By our integrated system of production from raw material to finished product, we will respond to the needs for greater sophistication and diversity from industrial equipment to ordinary products.
