High Speed Steel Plate (HSS Plate) is a premium alloy tool steel material widely recognized for its high hardness, outstanding wear resistance, excellent red hardness, and reliable toughness. It is specially designed for demanding industrial environments that require high load capacity, high temperature resistance, and precision machining performance.
At Hanli, our High Speed Steel Plates are produced through advanced rolling and heat-treatment processes, ensuring stable microstructure, excellent dimensional accuracy, and long service life even under prolonged heavy-duty operations.
These plates are widely used in the production of cutting tools, molds, automotive components, and aerospace precision parts. In many machining and tooling applications, HSS plates are also used together with M2 STEEL BAR to manufacture complete tool systems, providing consistent performance across different component forms.
Available Material Grades
Our High Speed Steel Plates are available in multiple high-performance grades to meet different tooling and industrial requirements.

Key Advantages
High Hardness & Exceptional Wear Resistance
After proper heat treatment, HSS plates can achieve a hardness level of 62–65 HRC, providing outstanding resistance to wear, deformation, and mechanical stress.
Even in demanding processes such as cutting, stamping, and forming, the material maintains excellent dimensional stability, significantly extending the service life of tools and components.
Superior Red Hardness
High Speed Steel Plates maintain their hardness and cutting performance even at working temperatures of 500–600°C.
This makes them particularly suitable for:
High-speed cutting operations
Continuous machining
Heavy-duty industrial tooling
Excellent Toughness & Machinability
Despite its high hardness, HSS plate maintains sufficient toughness to reduce the risk of chipping and cracking during machining or operation.
The material supports various machining processes, including:
Turning
Milling
Grinding
Precision forming
This allows manufacturers to produce complex and high-precision parts efficiently.
Industrial Applications
1. Machining Tool Manufacturing
High Speed Steel Plate is a core material for manufacturing various cutting tools.
