Overview of Powder High-Speed Steel Products:

1. Core Definition:

Powder high-speed steel is a type of high-speed steel produced using powder metallurgy technology. Molten steel is atomized into extremely fine powder by high-pressure gas or centrifugal force, then densified into steel ingots through hot isostatic pressing, and finally processed into materials by hot working.

2. Core Technical Advantages: Compared with traditional cast and forged high-speed steel, its core advantages are:

No carbide segregation: It completely solves the problem of carbide inhomogeneity caused by traditional processes, with fine carbide particles and uniform distribution.

Higher alloy content: It can produce high-alloy grades (such as high vanadium and high cobalt) that cannot be smelted by traditional methods, achieving extremely high hardness, wear resistance and red hardness.

Isotropy: Mechanical properties and heat treatment deformation are consistent in all directions.

Excellent grindability: Even with high vanadium content, it still has good grindability due to fine carbides.

3. Core Value Proposition:

Powder high-speed steel represents the pinnacle of high-speed steel technology. With its unparalleled wear resistance, excellent red hardness and consistent isotropic properties, it has become the preferred tool material for dealing with the most difficult-to-machine materials (such as titanium alloys, nickel-based superalloys, and high-hardness die steel). Although the cost is high, the improvement in processing efficiency and the extension of tool life brought by it make it irreplaceable in the field of high-end manufacturing.
