FAQ

Spray-formed high-speed steel also belongs to powder metallurgy high-speed steel. Spray forming is an advanced technology for the preparation of high-performance materials by means of rapid solidification.This technology eliminates the problem of macrosegregation of components and has the organizational characteristics of powder metallurgy. 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 by the impact. 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.

Answer: We supply a wide range of High Speed Steels (HSS), covering both conventional and advanced spray forming / ESR grades:

  • M2 (1.3343) – the most widely used HSS grade for general cutting tools
  • M42 (1.3247) – cobalt-alloyed HSS with excellent wear resistance and red hardness
  • T1 (1.3355) – tungsten-based HSS for high toughness applications
  • 1.3377 – spray forming grade with balanced hardness and toughness
  • Customized ESR & Spray Forming HSS – available upon request for special applications

With this broad portfolio, we can meet customer needs from standard cutting tools to premium molds and dies.

High speed steel is an alloy steel with high hardness, wear resistance and high temperature resistance, which is widely used in various cutting tools and knives, including turning tools, milling cutters, drills and saw blades. Similar to high-speed and high-carbon steels, heat treatment is used to increase the hardness of the tool by quenching and maintain moderate toughness by tempering.

High-speed steel is refined with tungsten, chromium, molybdenum, cobalt, vanadium and other metal elements, and its Rockwell hardness reaches (HRC60) at room temperature. Its high-temperature strength is greatly improved compared to high-carbon steel, and its Rockwell hardness can be maintained at about (HRC40) or above at 600 degrees Celsius, and the blade can still remain sharp, while high-carbon steel has been significantly softened at the same temperature and lost its cutting ability.

Answer: Spray Forming HSS delivers performance very close to Powder Metallurgy (PM) HSS, but at a much lower cost.

  • Both materials have uniform structures and excellent toughness.
  • PM HSS offers the absolute highest wear resistance, but it is very expensive.
  • Spray Forming HSS provides 90–95% of PM HSS performance while remaining far more cost-effective.

In short: PM HSS is the premium option, while Spray Forming HSS is the cost-performance champion.
