This tool steel specification is noted for its resistance to abrasion. It offers excellent dimensional stability in hardening. After heat treatment the tool steel is hard, durable, dense, and is immune from sinking in use. It offers a measure of corrosion resistance when polished. In general, the applications of 1.2080 tool steel resemble those of 1.2379 but it should be remembered that 1.2080 has better wear resistance of the two steels and is preferred for such items as shear blades. Owing to its higher wear resistance, 1.2080 tool steel is slightly more difficult to grind than 1.2379.
