ASTM A681 Standard Specification for Tool Steel

It has maximum shock resistance and high compression strength, which gives it good deformation resistance in use, while retaining good toughness. Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard. Maintain above F C during welding. S7 tool steel also has medium hot work characteristics, making it a versatile tool steel for both cold and warm shock applications, as well as plastic molds that require high hardness.

D2 is very wear resistant but not as tough as lower alloyed steels. Tools and dies made from O1 Flat Ground will have good wearing and abrasive qualities.

H10 tool steel is recommended for difficult hot work tooling applications. H11 tool steels have the higher toughness, with some reduction in wear resistance and temper resistance. H13 Tool Steel 1. It can be quenched in air, exhibiting minimal distortion on hardening.

The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard. Temper 25F 15C below original tempering temperature. Preheat to original tempering temperature F C minimum. O1 Tool Steel 1. D3 cold work steel has very high wear resistance against abrasive astk adhesive wear.

H10 Tool Steel is one chromium hot-work tool steel ashm exhibits excellent resistance to softening at elevated temperature. This is not an anneal, and after the forging is cold, it must be properly annealed. S7 tool steel is easy to machine in the annealed condition and can be readily heat treated.

This abstract is a brief summary of the referenced standard. AISI S7 tool steel is astn shock-resistant air hardening steel. Founded inFuShun covers an area of square meters, annual sales volume of tons. Sales Manager for European, African, Asia market: The material shall be made by an electric melting process.

ASTM A Grade D2 cold-drawn Steel – Matmatch

S7 tool steel is normally tempered one and one-half hours to two hours for each inch of greatest crosssection. Small, simple awtm can be cooled slowly in dry lime, ashes or other insulating material.

Sales Manager for American, Oceanian, Asian market: The special purpose mold steel P20 steel plate is commonly used for plastic injection mold cavities and tooling. Historical Version s – view previous versions of standard. H13 Tool Steel is chromium hot-work tool steels. It is recommended for both hot and cold shock applications such as rivet sets, chisels, punches, moil points, hot headers and gripper dies.

This specification covers the chemical, mechanical, and physical requirements for available wrought alloy tool atsm products.

ASTM A681 Grade D2 cold-drawn

Due to H13 steel excellent combination of high toughness and fatigue resistance, AISI H13 hot work tool steel is used more than any other tool steel in tooling applications. AISI H12 steel is a 4. It shall be made from ingots that have been reduced in cross section in such a manner and to such a degree as to ensure proper refinement of the ingot structure.
