It can be quenched in air, exhibiting minimal distortion on hardening. Back to Top Applications S7 tool steel has an ast combination of properties, making it suitable for an extremely wide range of tool and die work — where shock-resistance, medium hot-work properties, or ease of machining and heat-treatment are most important.

ASTM A Grade D2 cold-drawn Steel – Matmatch

This is not an anneal, and after the forging is cold, it must be properly annealed. A2 Tool Steel 1. The special purpose mold steel P20 steel plate is commonly used for plastic injection mold cavities and tooling.

D3 cold work steel has very high wear resistance against abrasive and adhesive wear. ASTM does xstm give any warranty express or implied or make any representation that the contents of this abstract are accurate, complete or up to date.

Tools and dies made from O1 Flat Ground will have good wearing and abrasive qualities. Otai steel supplies A6881 mold steel for high end plastic mold steel. Founded inFuShun covers an area of square meters, annual sales volume of tons. S7 tool steel is also suited for short-run dies used in coldforming, blanking, and bending.

H11 tool steels have the higher toughness, with some w681 in wear resistance and temper resistance. O1 Tool Steel 1. It has maximum shock resistance and high compression strength, which gives it good deformation resistance in use, while retaining good toughness.

Temper 25F 15C below original tempering temperature. Small, simple forgings can be cooled slowly in dry lime, ashes or other a861 material. Quenching in oil gives an increased risk for dimensional changes and cracks. The tempering temperature varies according to the intended use.

ASTM A681 Grade D2 cold-drawn

Maintain above Z681 C during welding. L6 Tool Steel 1. H10 tool steel is recommended for difficult hot work tooling applications. H10 Tool Steel is one chromium hot-work tool steel that exhibits excellent resistance to softening at elevated temperature.

Contact Lists General Manager: This specification covers the chemical, mechanical, and physical requirements for available wrought alloy tool steel products. The selection of a material for a particular application will depend upon design, service conditions, and desired properties. This abstract is a brief summary of the referenced standard.

P20 Steel Plate 1. The values given in parentheses are mathematical conversions to SI units that are provided for information only aatm are not considered standard. 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.

S7 tool steel is a shock resisting tool steel with excellent toughness and high strength, along with 6a81 wear resistance. AISI S7 tool steel is a shock-resistant air hardening steel. Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard. S7 tool steel also has medium hot work characteristics, making it a versatile tool steel for asm cold and warm shock a618, as well as plastic molds that require high hardness.

NAK80 steel is a precipitation or age-hardened mold steel with a uniform through hardness of approximately 40 HRC.

Back to Top Welding: Fushun Special Steel Co. ASTM O2 steel is widely used for universal use. S7 tool steel is normally tempered one and one-half hours to two hours for each inch of greatest crosssection. Sales Manager for American, Oceanian, Asian market: It is informational only and not an official part of asgm standard; the full text of the standard itself must be referred to for its use and application.

Cool to F ast, after welding. D2 Tool Steel 1. Back to Top Workability Forging: Reanneal or temper F C for 4 hours after welding. Chemical composition, hardness, macrostructure and decarburization of the material shall conform to the requirements in accordance to the referenced ASTM documents itemized herein. The material shall be made by an electric melting process. AISI P20 Steel Plate Material is a versatile, low-alloy tool steel that is characterized by good toughness at moderate strength levels.

AISI S7 steel has exceptional impact properties plus the highest hardenability of shock resisting grades of tool steel. D2 is very wear resistant but not as tough as lower alloyed steels.
