Brian Fasteners manufactures High Speed Steel T1 Bars in Houston, USA. T1 is a general-purpose HSS grade that offers a balance of cost, workability, and red hardness. Produced through vacuum melting and hot rolling, these bars maintain metallurgical consistency and tight dimensional control. Commonly used for drills, taps, and saws, T1 is supported by Brian Fasteners with customized lengths, quick delivery, and technical expertise. Ideal for making general-purpose cutting tools, T1 serves producers needing dependable HSS material at competitive pricing.
HSS T1 contains about 0.95% carbon, 18.0% tungsten, 4% chromium, and 1% vanadium. Its tensile strength is approximately 2,200 MPa, yield strength around 1,800 MPa, and hardness up to 64 HRC after heat treatment. It offers red hardness to around 600 °C, good toughness, and overall wear resistance, making it appropriate for versatile cutting tool 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.
T1 bars are employed for general-purpose taps, drills, end mills, saw blades, and reamers. Common in automotive, appliance, and machine-shop sectors, they deliver reliable tool performance. Used to fabricate tools for wood, plastics, and steel, T1 bars allow efficient production with good tool life. Brian Fasteners supplies T1 bars that fulfill standard HSS tool-making needs with consistent quality and delivery.
We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
