Spray Forming High Speed Steel – High speed steel, 440C VG10 Stainless steel, Alloy steel,linear guideway, HSS tools manufacturer

Spray Forming 1.3377 High-Speed Steel (ASP2005) is a high-performance cutting tool steel designed for punching molds with high toughness, wear resistance, and strength. It provides a strong balance of wear resistance, toughness, and thermal stability, making it suitable for demanding industrial applications.

Produced using advanced spray forming technology, the steel features a fine-grain microstructure with uniformly distributed carbides. This reduces carbide segregation and improves cutting stability, edge retention, and tool life compared with conventional high-speed steels.

Compared with general-purpose grades such as M2 high-speed steel, 1.3377 offers improved hot hardness and heat resistance, allowing it to maintain cutting performance and edge strength under high temperature and mechanical stress.

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 it represents a distinct manufacturing process. It combines the advantages of traditional high-speed steel (HSS) and powder metallurgy HSS, providing an optimal balance of performance and cost-efficiency.

2. Cost-Effective Alternative to Powder Metallurgy Steel

Powder metallurgy high-speed steel can be cost-prohibitive for some applications. Spray forming HSS offers similar tool life and durability while being more affordable, allowing you to reduce material costs and improve overall production efficiency.

3. Upgrade from Conventional Imported Tool Steels

If you’re using traditional high-speed steel imported from Europe or Japan, consider switching to Spray Forming HSS. It delivers better performance, competitive quality, and improved value while helping you cut costs without compromising tool reliability.

Product Advantages Of Spray Forming Steel

Fine grain structure and uniform carbide distribution improve wear resistance and edge stability.
Inhibits macrosegregation of alloying elements, ensuring uniform material properties.
Superior strength and toughness post-heat treatment, far surpassing the performance of high-quality electroslag steels.
Close tool life to powder metallurgy steels, while offering better cost efficiency.
Provides a perfect alternative to imported electroslag remelting materials with better quality at the same price.

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.
