HSP meaning in steel industry
HSP means hot dip galvanizing (HSP) is a metal surface treatment method that mainly involves immersing metal parts into molten zinc ingots to form a zinc protective layer on the metal surface. This process can effectively prevent metal corrosion and extend the service life of materials. Widely used in various industries such as construction, transportation, machinery, and electricity.
In the steel industry, "HSP" generally refers to a series of high-performance high-speed steels, particularly powder high-speed steels developed and produced by Japan's Hitachi Metals.
These steels are renowned for their exceptional hardness, wear resistance, red hardness (the ability to maintain hardness at high temperatures), and toughness. They are primarily used in the manufacture of demanding cutting tools, dies, and other wear-resistant components.
Core Advantages:
Powder Metallurgy Process: HSP series steels are mostly produced using powder metallurgy technology, which results in finer and more evenly distributed carbide particles within the steel. This significantly improves the steel's toughness, wear resistance, and isotropy, while reducing the carbide segregation common in traditional cast high-speed steels.
High Hardness and Red Hardness: Even at temperatures around 600°C, it maintains high hardness, making it ideal for high-speed cutting and hot working molds.
Excellent Wear Resistance: Effectively resists wear and extends the life of tools and molds.
Applications:
High-performance cutting tools (such as milling cutters, drills, taps, and broaches);
Cold-working molds (such as stamping and cold heading dies);
Wear-resistant parts;
Key components in high-tech fields such as aerospace.
