ASP2023 ASP23 S790 FAX31 M3:2 SPRAY FORMING High-Speed Steel

P23(ASP2023) is manufactured by our company’s original creative “Directional process”(RS ESR), The carbide particles are fine and uniformly distributed without segregation. The properties are better than M2/SKH-51, and is the perfect replacement of powder metallurgy ASP2023

ZEICIN ASP2023 HSS USES the original spray molding technology in China. Compared with the traditional HSS, it greatly improves the service life of the tool, which is close to the life of the powder HSS, and greatly improves the cost performance, saving the purchasing cost for customers and bringing win-win cooperation.
Meanwhile, We also provide various semi-finished products such as taps, drills and punches. The hardness is HRC66-68.

More Information

Technology process:	Spray forming is an advanced technology to produce the high-performance material by rapid solidification. The technology has solved the problem of the composition of the macrosegregation and has the characteristics of powder metallurgy. The high-speed steel is heated into molten metal, and then it is atomized; under the effect of gas injection, the droplet is accelerated and cooled down rapidly, When the collision of flying droplets in the precipitator, the spherical particles have been impacted then became flat, formed to sputtering film, Cooling effect of particle precipitation the rapid solidification, And the self-fluxing effect accumulation forming.
Property	The chemical composition of ASP2023 HSS steel is characterized by a large amount of heat generated at the cutting edge of the cutting tool and drill bit during machining, which increases the temperature of the tool and drill bit. In this processing environment, each chemical element plays its own role（Properties and applications: cobalt-free, for cold working and cutting tools.）: 1) tungsten can maintain its hardness and wear resistance in a certain high-temperature range; 2) chromium plays an important role in the hardenability, oxidation resistance and wear resistance of steel, and also plays a certain role in the secondary hardening; 3) vanadium plays an important role in secondary hardening and wear resistance of steel, but reduces grinding performance;
Application	ASP2023 HSS is widely used for cutting tools and drills in machining, especially for cutting tools with high performance, long life, high speed, and precision molding. It is also used to manufacture high-performance molds, rolls, high-temperature bearings, and high-temperature springs.
