D2 Tool Steel 1. S7 tool steel is normally tempered one and one-half hours to two hours for each inch of greatest crosssection.

Preheat to original tempering temperature Astk C minimum. About Us Founded inFuShun covers an area of square meters, annual sales volume of tons. Fushun Special Steel Co.

H11 tool steels have the higher toughness, with some reduction in wear resistance and temper resistance. Use hot work tool steel filler material or type filler material may be satisfactory for small repairs or welds away from working surface of tool.

Quenching in oil atsm an increased risk for dimensional changes and cracks. The material shall be made by an electric melting process. This is not an anneal, and after the forging is cold, it must be properly annealed.

Back to Top Welding: Founded inFuShun covers an area of square meters, annual sales volume of tons. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard. The selection of a material for a particular application will depend upon design, service conditions, and desired properties.

The special purpose mold steel P20 steel plate is commonly used for plastic injection mold cavities and tooling. S7 tool steel also has medium hot work characteristics, making qstm a versatile tool steel for both cold and warm shock applications, as well as plastic molds that require high hardness. It has maximum shock resistance and high compression strength, which gives it good deformation resistance in use, while retaining good toughness.
