Nestled in the vibrant industrial heart of Kinshasa, Sadiki Metals stands as a trusted partner for precision and durability. We take pride in manufacturing and supplying premium High Speed Steel T1 Bars, engineered to meet the rigorous demands of the modern workshop. Our commitment extends beyond mere supply; we provide local industries with the reliable, high-performance materials needed to drive productivity and innovation, ensuring that every tool crafted from our steel is built for exceptional results and long-lasting service.
The strength of our T1 bars lies in their sophisticated composition, which is primarily a blend of tungsten, chromium, and vanadium. This specific alloy recipe gives the steel its remarkable ability to retain hardness and cutting sharpness even when exposed to the high temperatures generated during fast machining operations. Essentially, this means your tools stay stronger and sharper for longer under intense working conditions, resisting wear and maintaining their edge through the toughest jobs.

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 should be stored in a dry, cool environment, protected from moisture and corrosive elements. They should be kept off the ground, ideally on shelves or in sealed containers.
Because of their unique ability to withstand heat and abrasion, T1 bars from Sadiki Metals are the material of choice for creating a wide range of high-performance cutting tools. They are expertly fashioned into drill bits, milling cutters, lathe tools, and saw blades that excel in high-speed operations on metals, plastics, and composites. Beyond cutting, this steel is also invaluable for making forming tools, punches, and dies that must endure significant pressure and wear, making it a cornerstone for tool and die shops and manufacturing plants.






We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
