Alloy Performance Advantages
Tungsten (W): Provides excellent red hardness at high temperatures
Chromium (Cr): Improves corrosion resistance and hardenability
Vanadium (V): Enhances wear resistance and toughness
Key Advantages of Our HSS Bar
Annealed Delivery Condition (Prepared for Further Processing)
Delivery hardness: ≤255 HB (annealed state, tested in accordance with ASTM E10)
Microstructure: Spheroidized annealed structure, uniform and fine, facilitating subsequent cold working and heat treatment
Decarburization depth: ≤0.20 mm (per side), meeting the requirements for precision tool blank production
Straightness: ≤2 mm/m, suitable for automatic lathe feeding applications
Excellent Toughness & Impact Resistance
Our HSS tool steel bars are engineered to withstand:
Heavy impact loads
High stress working environments
Ideal for forging dies and high-load tooling applications.
Outstanding Dimensional Stability
Our HSS bars maintain:
High precision under high-speed rotation
Resistance to deformation
Consistent machining accuracy
Perfect for precision tools and rotating components.
