D3 Cold Work Steel 1. About Us Founded inFuShun covers an area of square meters, annual sales volume of tons. Small, simple forgings can be cooled slowly in dry lime, ashes or other insulating material.

D3 cold work steel has very high wear resistance against a6811 and adhesive wear.

AISI H12 steel is a 4. AISI P20 Steel Plate Material is a versatile, low-alloy tool steel that is characterized by good toughness at moderate strength levels. Some equivalent steel is 1. Back to Top Applications S7 tool steel has an unusual combination of properties, making it suitable for an extremely wide range of tool a6881 die work — where shock-resistance, astj hot-work properties, or ease of machining and heat-treatment are most important.

D2 Tool Steel 1. It is recommended for both hot and cold shock applications such as rivet sets, chisels, punches, moil points, hot headers and gripper dies. P20 Steel Plate 1. Contact Lists General Manager: Back to Top Welding: S7 tool steel is normally tempered one and one-half hours to two hours for each inch of greatest crosssection.

D2 is very wear resistant but not as tough as lower alloyed steels. Referenced Documents purchase separately The a6681 listed below are referenced within the subject standard but are not provided as part of the standard.

H10 Tool Steel is one chromium hot-work tool steel that exhibits excellent resistance to softening at elevated temperature. AISI S7 tool steel is a shock-resistant air hardening steel. S7 tool steel is a shock resisting tool steel with excellent toughness and high strength, along with medium wear resistance.

It has maximum shock resistance and high compression strength, which gives it good deformation resistance in use, while retaining good toughness. This is not an anneal, and after the forging is cold, it must be properly annealed. The material shall be made by an electric melting process. Chemical composition, hardness, macrostructure and decarburization of the material shall conform to the requirements in accordance to the referenced ASTM documents itemized herein.

Back to Top Workability Forging: Otai steel supplies NAK80 mold steel for high end plastic mold steel. Sales Manager for American, Oceanian, Asian market: 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.

ASTM A Standard Specification for Tool Steel

AISI S7 steel has exceptional impact properties plus the highest hardenability of shock resisting grades of tool steel. 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.

H11 tool steels have the higher toughness, with some reduction in wear resistance and temper resistance.

H13 Tool Steel 1. S7 tool steel is also suited for short-run dies used in coldforming, blanking, and bending. Link to Active This link will always route to the current Active version of the standard.

Reanneal or temper F C for 4 hours after 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.

Quenching in oil gives an increased risk aatm dimensional changes and cracks. Due to H13 steel excellent combination of high a618 and fatigue resistance, AISI H13 hot work tool steel is used more than any other tool steel in tooling applications.

ASTM A Grade D2 cold-drawn Steel – Matmatch

Miss Summer summer fushunspecialsteel. It is informational only a6811 not an official part of the standard; the full text of the standard itself must be referred to for its use and application.

It can be quenched in air, exhibiting minimal distortion on hardening. NAK80 steel is a precipitation or age-hardened mold steel with a uniform zstm hardness of approximately 40 HRC.

ASTM A681 Grade D2 cold-drawn

Maintain above F C during welding. The tempering temperature varies according to the intended axtm. The special purpose mold steel P20 steel plate is commonly used for plastic injection mold cavities and tooling.

S7 tool steel is easy to machine in the annealed condition and can be readily heat treated. ASTM O2 steel is widely used for universal use. H10 tool steel is recommended for difficult hot work tooling atsm.

Sales Manager for European, African, Asia market: Historical Version s – view previous versions of standard.

Temper 25F 15C a861 original tempering temperature. This abstract is a brief summary of the referenced standard. Tools and dies made from O1 Flat Ground will have good wearing and abrasive qualities.
