Sales Manager for European, African, Asia market: Quenching in oil gives an increased risk for dimensional changes and cracks. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard. H10 Astm a681 Steel is one chromium hot-work tool steel that exhibits excellent resistance to softening at elevated temperature.

S7 tool steel is easy to machine in the annealed astm a681 and can be readily heat treated. It qstm maximum shock resistance and high compression strength, which gives it good deformation resistance in use, while retaining good toughness.

Reanneal or temper F C for 4 hours after welding. H11 tool steels have the higher toughness, with astm a681 reduction in astm a681 resistance and temper resistance. S7 tool steel also has medium hot work characteristics, making it a versatile tool steel for both cold qstm warm shock applications, as well as plastic molds that require high hardness.

This specification covers the chemical, mechanical, and physical requirements for available wrought alloy tool steel products. Astm a681 Summer summer fushunspecialsteel.
