Product Description

 

Product Description

_{Hot Sale T1 High-Speed Steel Flat Bar for Cutting Tools}

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.

Product Parameters

Heat Treatment Process for T1 High-Speed Steel

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.

1. Annealing:

   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

2. Quenching:

   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.

3. Tempering:

   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.

Applications

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.
