Tools and dies made from O1 Flat Ground will have good wearing and abrasive qualities. D2 is very wear resistant but not as tough as lower alloyed steels.
The material shall be made by an electric melting process.

Cool to F 65C after welding. Historical Version s – view previous versions of standard.
The special purpose mold steel P20 steel plate is commonly used for plastic injection mold cavities and tooling. S7 tool steel is normally tempered one and one-half hours to two hours for each inch of greatest crosssection. Fushun Special Steel Co.
1.2355 ASTM A681 S7 Tool Steel Flat Bar
AISI S7 tool steel is a shock-resistant air hardening steel. AISI P20 Steel Plate Material is a versatile, low-alloy tool steel that is characterized by good toughness at moderate strength levels. Quenching in oil gives an increased risk for dimensional changes and cracks.
AISI H12 steel is a 4. S7 tool steel is easy to machine in the annealed condition and can be readily heat treated. 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. A2 Tool Steel 1. AISI S7 steel has exceptional impact properties plus the highest hardenability of shock resisting grades of tool steel.
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.
Contact Lists General Manager: P20 Steel Plate 1. H13 Tool Steel is chromium hot-work tool steels.
Preheat to original tempering temperature F C minimum. Maintain above F C during welding. It is informational only and not an official part of the standard; the full text of the standard itself must be referred to for its use and application.
ASTM A – 08() Standard Specification for Tool Steels Alloy
L6 Tool Steel 1. This is not an anneal, and after the forging is cold, it must be properly annealed. D3 cold work steel has very high wear asfm against abrasive and adhesive wear. Temper 25F 15C below original tempering temperature. Back to Top Workability Forging: Back to Top Applications S7 tool steel has an unusual 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 A681, Tool Steels Alloy
Small, simple forgings can be cooled slowly in dry lime, ashes or other insulating material. It is recommended for both hot and cold shock applications such as rivet sets, chisels, punches, moil points, hot headers and gripper dies. Reanneal or temper F C for 4 hours after welding.
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.
ASTM does not give any warranty express or implied or make any representation that the contents of this abstract are accurate, complete or up to date. The tempering temperature varies according to the intended use.
H10 Tool Steel is one chromium hot-work tool steel that exhibits excellent resistance to softening at elevated temperature. It shall be made from ingots that have been reduced in cross section in such a manner and to such a degree as a81 ensure proper refinement of the ingot structure.
Founded inFuShun covers an area of square meters, annual sales volume of tons.
