T1 W18Cr4V SKH2 1.3355 High-Speed Steel

One of the commonly used tungsten high-speed steel is W18Cr4v, which is lactic steel, the longest used  tungsten high-speed steels . 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 omni-directional 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.

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.

Annealing:

• Heat treatment of steelAustenite decompositionAustenite 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.

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.

Tempering:

• Subsequently, the quenched steel is tempered at 540-560°C for at least two cycles (≥ 2 h) to achieve toughness and stability while keep CHP high hardness.

After Heat Treatment, Performance

T1 high-speed steel has the following properties after appropriate heat treatment:

• 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.

• Good Toughness：Well tempered titanium has high stability and resistance to breaking under high pressure.

Why Choose Our T1 High-Speed Steel?
