Product Description

Product Description
S7 die steel is heavy load impact resistant tool steel and medium carbon alloy steel. High strength S7 material has high chromium content, good tempering resistance and high temperature oxidation resistance. In addition, the steel also has excellent wear resistance, excellent etching processing, excellent wire cutting and excellent impact toughness properties. After annealing and softening, the original structure of rolled bar is F+C, which must be used after heat treatment.
