P30 high-speed steel is made using our self-developed directional process, which allows precise control of the steel structure. This process creates fine and evenly distributed carbides without segregation, avoiding the common problems found in traditional manufacturing methods. As a result, P30 offers stable and consistent performance.
Thanks to this advanced process, P30 high-speed steel provides higher hardness, better wear resistance, and stronger cutting performance than imported M35 and M42 high-speed steels, and can fully replace powder metallurgy steel ASP2030 in demanding applications.

We use a unique Rapid Solidification Electroslag Remelting (RS-ESR) process to produce high-quality steel ingots. This process creates a fine and uniform carbide structure with a dense and compact microstructure. As a result, the steel shows strong grain boundary bonding, excellent wear resistance, high red hardness, and good toughness. Its overall performance is better than similar domestic materials and also superior to imported materials from Japan and Europe in terms of carbide size and distribution.
The RS-ESR process significantly reduces carbide grain size and minimizes the ledeburite carbide network, which helps lower material segregation and improve overall material quality.
This technology is independently developed by our company and is a unique process in China.
During RS-ESR processing, rapid cooling and fast solidification create a shallow molten pool. Carbides solidify quickly before they have time to grow, which keeps them small and evenly distributed.
By shortening carbide growth time, the process prevents the formation of coarse carbides and ensures a stable and high-quality microstructure.
P30 high-speed steel offers high hardness, strong wear resistance, and a stable microstructure, making it suitable for many types of cutting tools and industrial knives.
Common applications of P30 high-speed steel include:
Drills
Taps
Punches
Band saw blades
End mills
Tufting machine knives
Paper cutting knives
Under tough working conditions, P30 high-speed steel provides long tool life and stable performance. It is a reliable replacement for M35, M42, and ASP2030, and is widely used in high-performance tool manufacturing.
