HSS T15 Tool Steel China Supplier, Otai Special Steel supply T5 high Speed steel in round bar, flat, square bar, plate, sheet.

AISI T15 Tool Steel is a W High Speed Steel. HSS T15 steel have high temperature hardness and red hardness and hardness is high, easy to grinding. ASTM T15 have very good red hardness, Abrasion resistance about 5 to 7 times of conventional high speed steel, toughness comparable with M2 . Widely used in rolling gear, broach, milling cutter, taps, and need to wear resistance of the stamping die, precision cutting, etc. Especially the aviation industry of choice for high temperature alloy turbine disk flat broach material, and production processing hard cutting and qualitative material of the tap and die cutter. Due to their high tungsten content, high wear resistance, suitable for precision stamping die, especially the artifacts produced by wear or when using life is not long enough, can replace with T15, suggested use on stamping workpiece thickness had better not more than 2.5 MM.

Elastic modulus: 190-210 GPa

SAE T15 Tool Steel Physical Properties

Density: 8.7kg/cm3

Thermal expansion: 9.7 x 10-6/°C   at 20-200°C more

 

Forged of T15 HSS Steel metal material

Pre-Heating to 650-750℃，Then heat to forged temperature. Soak at 1204°C, ensure heat thorough. Then start forged, the forged temperature no low than 950℃. After forging, cool slowly.

Heat Treatment of SAE T15 Steel-A600 High Speed Tool Steel
  • T15 HSS Steel Annealing

Slowly heat to 816-871℃，then slowly Cool to 538℃(1000℉) in heat treatment furnace. Then cool in air. After annealing hardness HBS: 240-300 Max.

  • T15 tool Steel Hardening

T15 steel having very high hardenability and should be hardened by cooling in still air. The use of a salt bath or controlled atmosphere furnace is desirable to minimize decarburization, and if not available, pack hardening in spent pitch coke is suggested.

  • Quenching of HSS T5 Tool Steel material

Application of AISI T15 tool Steel ASTM HSS

AISI T15 high speed tool steel is Suitable for heavy cutting, high cutting efficiency and large feed difficult-to-machine materials of high hardness, particularly on the place of tungsten carbide parts have high evaluation; Wear resistance is about 5 to 7 times of high speed steel more traditional, toughness comparable with M2, widely used in rolling gear, broach, milling cutter, taps and need to wear resistance of the stamping die, precision cutting, etc. Especially the aviation industry of choice for high temperature alloy turbine disk flat broach material, and production processing hard cutting and qualitative material of the tap and die cutter. Due to their high tungsten content, high wear resistance, suitable for precision stamping die, especially the artifacts produced by wear or when using life is not long enough, can replace with T15, suggested use on stamping workpiece thickness had better not more than 2.5 MM.
