Spray Forming M2 High-Speed Steel (1.3343 / SKH51)

Spray Forming M35 High-Speed Steel (1.3243 / SKH55)

Spray Forming M2 High-Speed Steel is produced using advanced spray forming technology, creating a fine microstructure with evenly distributed carbides. This improves wear resistance and cutting stability.

Compared with conventional M2, spray forming M2 offers better hardness stability, higher wear resistance, and good toughness. It also reduces carbide segregation and improves tool reliability.

It is widely used for high-precision cutting tools, industrial tooling, and wear-resistant mechanical parts.

Why Choose Spray Forming High-Speed Steel?

1. A Material Between Conventional HSS and Powder Metallurgy HSS

Strictly speaking, spray forming steel belongs to the powder metallurgy family, but the manufacturing process is different. It represents a technology positioned between traditional high-speed steel and powder metallurgy high-speed steel, combining the advantages of both.

2. Cost-Effective Alternative to Powder Metallurgy Steel

If powder metallurgy high-speed steel is too expensive for your application, spray forming HSS can be a practical alternative. It offers tool life close to powder metallurgy steel, while helping reduce material costs and improve overall production efficiency.

3. Upgrade from Conventional Imported Tool Steels

If you are currently using conventional high-speed steel imported from Europe or Japan at high prices, our spray forming HSS can be an excellent replacement. It provides better cost performance, competitive quality, and improved value, helping you reduce costs while maintaining reliable tool performance.

Product Advantages Of Spray Forming Steel

Fine grains and carbides are evenly distributed in a granular form.
Inhibit macrosegregation of alloying elements
Fine microstructure with uniformly distributed granular carbides.
After heat treatment, the mechanical properties are excellent, and the strength and toughness are significantly better than those of high-quality electroslag steel
Service life close to powder steel
Improve the quality of domestic materials under the premise of the same price
Perfectly replace and surpass imported electroslag remelting materials

Priniple of Spray Forming

First, the raw materials are heated into molten metal, and then gas atomized.
Under the action of the gas jet, the droplets are accelerated to fly and rapidly cooled.
When the high-speed flying droplets collide in the precipitator, the spherical particles are impacted. It becomes flat to form a sputtering sheet.
The particles solidify rapidly through the cooling effect of the precipitator, and accumulate and form under the action of self- fluxing.

Spray Forming HSS M2 Heat Treatment Process

Annealing

Softens the steel to about HB 255, relieving internal stress and improving machinability.

Quenching

Heat to 1180–1205°C, then rapidly cool to obtain high hardness and wear resistance.

Tempering

Temper at 540–570°C to balance hardness and toughness. Final hardness is 64–66 HRC.
