High Speed Steel T1 is a tungsten-molybdenum alloy steel, primarily made up of 18% tungsten, 4% chromium, 1% vanadium, 0.7% carbon, along with trace amounts of molybdenum and manganese. It boasts remarkable hardness (typically between 62–64 HRC) and wear resistance, even when cutting at temperatures soaring up to 600°C (1112°F). T1 steel is also known for its toughness and red hardness, making it perfect for high-speed machining tasks. Its ability to keep the cutting edge sharp and resist deformation under heavy loads significantly extends tool life in challenging machining conditions.

Yes, High-Speed Steel T1 bars can be welded, but it requires specialized techniques like preheating and post-weld heat treatment to prevent cracking and maintain their hardness and strength properties.
High-Speed Steel T1 bars resist corrosion due to the presence of chromium, which forms a protective oxide layer on the surface. This enhances their resistance to moisture and chemical wear, prolonging tool life.
Rupal Metals’ High Speed Steel T1 Bars are extensively utilized in crafting cutting tools like drills, taps, milling cutters, saw blades, and lathe tools. Its capacity to retain hardness at elevated temperatures makes it an excellent choice for high-speed machining of both ferrous and non-ferrous metals. T1 steel is particularly popular in industries such as automotive, aerospace, heavy machinery, and tool & die making, where precision and durability are paramount. Additionally, it finds applications in cold and hot forming tools, thread rolling dies, and gear cutters.
We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
