One of the commonly used tungsten high-speed steels is W18Cr4v, which is a lactic steel, the longest used tungsten high-speed steel. They are sometimes known as "white steel", "front steel", "wind steel"(again, an air-cooled hardened steel), like other high-speed steels.
W18Cr4V is an omnidirectional steel that can be used for cutting when hot and hard requirements are less significant. W18Cr4V can also be used for cold service; Tool examples include punching, forming, stamping, etc.

A highly controlled heat treatment process allows T1 high-speed steel to reach the desired hardness, toughness, and wear resistance. This is done through several processes like Annealing, Quenching, Tempering etc, with each process requiring specific temperatures in order to produce a better quality end product.
Heat treatment of steelAustenite decomposition is held at 850-870°C for some hours and slowly cooled to 600°C to relieve internal stress and refine the carbide structure to improve machinability
The steel is heated up to 850°C at first and then quickly raised up to either 1250-1270°C (salt bath furnace) or 1260-1280°C (box furnace). Then it is quenched in air or oil to reach maximum hardness.
Subsequently, the quenched steel is tempered at 540-560°C for at least two cycles (≥ 2 h) to achieve toughness and stability while keeping CHP high hardness.
Outstanding Hardness: Hardness range of 63-64 HRC, providing excellent cutting performance.
Exceptional Resistance to Wear: The elevated tungsten percentage results in superior wear resistance for a longer-lasting tool.
Increased Red Hardness: Retains cutting ability and performance at higher temperatures.
The ability to save without quality sacrifice
We guarantee that our Tl high-speed steel is not inferior to high-class ones from Japan, Europe, and the USA at a more favorable price. By moving to proficient smelting and employing stricter standards, we are able to hit top performance at cost-effective pricing.
We adopted a new EAF + LF + VD + Rs ESR process, the heat is uniform in the microstructure, the carbide distribution more finer. This improves high-speed steel toughness, resistance, and overall performance.
Heat treatment with precision control:
Applied cast hardened: Our optimized heat-treatment process provides Tl steel with optimal red hardness, hardness retention, and resistance in high-speed cutting.
Consistent Material Quality:
Raw material selection, processing, and quality inspection are all in our hands, meaning we can deliver consistent and repeatable quality of each batch of Tl high-speed steel.
Adheres to International Quality Standards:
High speed steel Tl complies with a series of international standards as GB/T 9943-2008, AISI Tl, JIS SKH2, and DIN 1.3355.
Leading Research &Development:
We work with Shanghai University and the Beling Iron & Steel Research Institute on national high-performance materials research and on independent R&D of the exclusive Rapid solidification Electro-Slag Remelting (Rs EsR) technology to improve metals in terms of purity
and performance.
Exclusive Proprietary Technology:
Together with Shanahgi University and Beling Iron & Steel Research Institute, we developed a proprietary Rapid Solidification Electro-Slag Remelting (RSESR) process to greatly enhance Tl purity and carbide distribution.
Tl is 100% tungsten-based, while molybdenum-based HSS, such as M2, is not. Making it particularly suitable for applications requiring extreme wear resistance e, high-speed cutting, and long tool life.
Working with T1 / SKH2 High-Speed Steel in Application:
The T1, W18Cr4V1, SKH2, and 1.3355 high-speed steels are widely used in applications needing high hardness, wear-resistance, and high-temperature strength. Key uses include:
1. Metal cutting tools (e.g., drills, milling cutters, as well as lathes) for high-speed, in addition to high-temperature situations.
2. Moulds for die-casting and stamping because of their wear-resistance.
3. Measuring and inspection instruments, precision tools
4. Automotive parts and tools in engine and transmission manufacturing.
5. Aerospace and military applications that demand strength and corrosion resistance at high temperatures.
