Starc Metals, located in Canberra, Australia, stands out as a top manufacturer and supplier of premium metals, with a special focus on precision-engineered High Speed Steel (HSS) T1 Bars. They’ve built a solid reputation by blending cutting-edge metallurgical techniques with rigorous quality control, ensuring that each T1 bar meets the highest industrial standards. These bars are highly sought after for their remarkable hardness, wear resistance, and their ability to maintain strength even at high temperatures. Catering to a variety of industries like tooling, machining, and engineering, Starc Metals delivers dependable solutions for professionals in need of durable, high-performance HSS T1 Bars for precision tasks.
High Speed Steel T1 Bars are primarily made up of tungsten (around 18%), along with carbon, chromium, vanadium, and manganese, creating a well-balanced chemical profile that enhances performance. This unique composition results in T1 bars achieving exceptional hardness, typically ranging from 62 to 64 HRC after heat treatment, along with excellent wear resistance and high toughness. Their capacity to maintain cutting efficiency at elevated temperatures makes them perfect for high-speed machining applications. The bars feature a uniform microstructure, consistent dimensional stability, and resistance to deformation, ensuring they perform reliably even under tough operating 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.
These High Speed Steel T1 Bars find extensive use in manufacturing cutting tools, drills, taps, end mills, and other precision machining instruments. Their outstanding hardness, wear resistance, and thermal stability make them ideal for high-speed operations across metalworking, automotive, aerospace, and general engineering sectors. T1 bars are also utilized in shaping dies, forming tools, and gear-cutting processes where durability and performance are essential. By offering reliable strength and keeping sharp cutting edges even in extreme conditions, T1 bars from Starc Metals guarantee efficiency, accuracy, and longevity in various industrial applications.
We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
