High Speed Steel T4 (ASTM A600) is a tungsten molybdenum alloy high speed steel, with good wear resistance, high temperature resistance, suitable for the manufacture of all kinds of precision cutting tools. It includes sculpted drill, milling cutter, thread cutting tool, rolls, and other high-strength, high-load tools, etc. T4 has good thermal stability and high hardness, thus it can maintain excellent processing performance at high temperatures.

The best combination of hardness, toughness, and wear resistance conditions in T4 HSS is achieved by a multi-part heat treatment process. Heat treatment process includes:
T4 should be annealed after hot working. The steel is raised to 860 °C (maximum heating rate of 220 °C/hour) and soaked at this temperature, followed by air cooling slowly in the furnace. Its annealed hardness is under HB255, which is much easier to machine and form.
The T4 steel is tempered by heating to 1260-1290°C, followed by oil quenching, air quenching, or bath quenching at 550°C, and exhibits a hardness of 63-66 HRC, which is quite hard and can be utilized for high-speed cutting and tooling.
T4 steel was tempered at 560-580°C for two cycles (minimum of 2 h each) after hardening. As it's a little hard at that point, reducing it relatively between 64-65 HRC results in good toughness and wear resistance well as its cutting ability.
1.Outstanding Hardness:
After hardening, reaches 63-66 HRc hardness, with good high-speed conditioning cuttingperformance.
2.Superior Wear Resistance:
The high tungsten content greatly increases its wear resistance and prolongs tool life, even in the mostextreme environments.
3.Increased Red Hardness:
T4 retains its cutting power and efficacy at high temperature, allowing for speed cutting andmachining in hot areas.
4. Good Toughness:
T4 is still a high toughness state, which prevents the tool from breaking and enables it to withstandmachining in high-pressure conditions.

Specializing in Tungsten High-Speed Steel:
T4 is a 100% tungsten-based steel, known for exceptional wear resistance and the ability to cut at high speeds. This makes it perfect for the industries that need tools to work in the most extreme conditions.
T4 HSS is suitable for many applications, especially in industries where it requires hardness, wear, and high-temperature strength. Key applications include:
Cutting Tools: High-speed cutting tools like taps, drills, and milling cutters for precision machining applications and high temperatures.
Forming and Punching Tools: Tools used in punching, stamping, and extruding operations.
Thread Cutting Tools: They are used for cutting accurate threads in metals and alloys.
Die Cutting Tools: Moulds and dies used in die-casting and stamping processes.
Can T4 High-Speed Steel be customized?
YES, we provide custom requirements base services by dimensions, hardness and shapes. We will make sure the material is tailored to your specific needs, working in close collaboration with your team. On top of raw material supply, we can also make secondary processing, such as producing the thread taps, broaches, drills and so on semi-finished or finished goods, in order to promote your process and add efficiency.
How to care for T4 High-Speed Steel tools?
As a tool sustainability practitioner, monitoring tool sharpness and tool grinding is a key component of getting the most out of your tool life. Maintaining temperatures during cutting and applying proper cooling, will also prolong the service life of T4 tools. That means that we can provide you with post-processing services to enhance your tools performances, and with time, we even ensure that they stay up to your high demands.
How do you maintain quality of product?
A rigorous quality control process is executed at every step of the production process:
Material Selection: The raw materials come from reliable providers and are top notch.
Comprehensive Testing: All batches are thoroughly analyzed for chemical composition , hardness, and micrstructure to guarantee accuracy and absolute compliance with global quality standards (ISO 9001, for example).
Post-Processing Services:We also offer heat treatment and other value-added post-processing services to meet additional performance needs.
Every batch of our products is closely monitored and tested to the industry's quality specifications ensuring that you have consistent high standard, quality materials every time.
How is your T4 High-Speed Steel different from other brands?
The combination of material properties makes T4 High-Speed Steel(AISI T4) an excellent option even at reduced cost, ensuring high hardness(63-66 HRC), wear properties and high-temperature strength. We pride ourselves on performance per price and we adopt state-of-the-art production methods like EAF + LF + VD + RS ESR processes that guarantee top tier uniformity and carbide distribution.
