Powder Metallurgical High Speed Tool Steel : TSP23

Main Characteristic

TSP23 is a powder matal with chemical composition same as high speed tool steel grade Din.3344 (HS6-5-3)
Through the technique of Powder Metallurgy in its production, this result in homogenous without segregation.
Fine structure are obtaine, carbide spreading is equally throughout its structure.
Besides, purity and cleanliness are higher than high speed tool steel as produce under conventional method.
This result in high performance with toughness when compare to other tool steel or high speed tool steel
Properties in toughness and wear resistance can maintain until the red hot temperature.
With its fine , purity and equally structure, it is easy in cutting and polishing as well as machining
to shape by any mean.

TSP23 suitable to make high strength mold whilst maintain high toughness still possible.
Also, good for mold that need long life of cutting edge like blanking , stamping, threading mold
High Wear resistance mold such as deep drawing, high steel pressurize mold, cold pressing mold
which require long life or complex profile is in this case.
For example, engineering injection plastic mold. Moreover, it also good for any cutting tool , lathing knife,
tapping, drilling tool which will last longer any high speed tool.

OutStanding Properties

Homogeneity of chemical composition throughout the structure.
Purity and more clean than other production process.
Carbide come in small and round size with equal distribution throughout the structure.
Mechanical properties are equal in any direction.
High toughness as compare to general high speed tool
Easy to machinng , milling, grinding due to delicate and equally spreading structure.
Hardness at red hot (approx 600c) still at its best.
Can maintain cutting edge with toughness at its best result in long life tooling.
Wear resistance are higher than other high speed tool steel.
Can do nitriding and water tempering with best quality
Hard surface by PVD and CVD is at its best.


Performance and tool life of mold or tool always up to materials quality.
Function of each mold and tool always posses enough hardness, strength properties
Said properties never comes together in single materials. Tough materials always posses low tensile.
But in many case, requirement need both strenth and toughness at the same time.
For example, blanking high tensile steel. Powder metallurgy technique which is used in high speed tool
steel such as TSP23 and TSP4 is the answer to this. Qualification can be obtained in every aspect.
Toughness, Wear Resistance, high tensile strength comest together. This is best for various task especially
Cutting tools Cold working tools Wear and longer life can be achieved result in lower cost in long run.

Sample of application are
     Cutting tools for hard cutting condition
     High speed cutting , high abrasive condition
     Milling knife, Tapping, drilling
     Reamer, Hobbs, Threading
     And other milling tools
     Cold working tools
     Mold and parts for cold work such as
     Blanking , cold extrusion, Deep drawing
     Cold forging and rolling wheel.
