Anucha Metals is a reliable manufacturer and distributor of **High Speed Steel T1 bars** based in Bangkok, Thailand. The company, known for its excellence and accuracy, provides T1 grade HSS bars ideal for high-performance cutting and machining operations. Anucha Metals employs state-of-the-art production techniques and rigid quality control to achieve consistent material integrity and performance. Anucha Metals’ T1 bars are extensively supplied to toolmakers, automotive markets, and engineering industries throughout Thailand and overseas. Excellent hardness and wear resistance characterize Anucha Metals’ T1 HSS bars to satisfy customers demanding higher cutting efficiency and tool longevity.
**T1 high speed steel bars** have about 0.70–0.80% carbon, 18% tungsten, 4% chromium, and 1% vanadium. The high tungsten content provides T1 steel excellent hardness and wear resistance, particularly under high-speed cutting applications. Mechanically, T1 has excellent edge retention, red hardness, and compressive strength, and hence it suits applications with long-term exposure to high temperatures. While less formidable than molybdenum-containing grades such as M2, T1 offers better hot hardness and is able to withstand cutting capability even in the face of high friction and heat stress when in use.

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.
**High Speed Steel T1 bars** find extensive applications in the production of cutting tools such as lathe tools, planer blades, reamers, milling cutters, and metal saws. Their capacity to retain hardness at elevated temperatures renders them perfectly suitable for high-speed cutting processes in hardened steels and alloys. T1 HSS bars are utilized in cases where utmost hardness and wear resistance are desired, especially in heavy-duty or continuous machining. Businesses like automotive, aerospace, die and mold making, and precision engineering depend on T1 for toolmaking that requires long lifespan, dimensional stability, and repeatable cutting performance under harsh conditions.
We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
