Chung Metal Manufacturer & Suppliers in Da Nang, Vietnam, provides a wide variety of High Speed Steel (HSS) bars for cutting, tooling, and machining applications. We provide HSS bars in various grades (e.g. M‑series, T‑series) with accurate heat treatment and certification. Our HSS bars are dimensionally stable, metallurgically uniformed, and ready for toolmakers and fabricators to utilize in precision uses. With good quality control and supply reliability, Chung Metal is a reliable source of high performance tool steel stock.
HSS alloys have high carbon (≈0.8–1.5%) and other alloying elements like tungsten, molybdenum, chromium, vanadium, cobalt (in some grades), and sometimes high levels of other carbide formers. They can attain hardness levels of ~60–67 HRC (grade depending), good toughness, and good retention of hardness at high temperatures (red hardness). Tensile strength in the hardened state can be over 1,000 MPa. They possess wear resistance, toughness, and the capacity to cut at high rates without quick softening.
High-speed steel (HSS) bars are sized based on their cross-sectional dimensions (diameter for round bars, width/thickness for flats, or side length for square bars) and overall length. Standard sizes often follow industry specifications (e.g., ASTM, DIN) and are available in a range of diameters (e.g., 3mm to 200mm or more) and lengths (commonly 1-6 meters). Custom sizes can also be produced based on application needs.
Consider grade, hardness, toughness, heat resistance, tensile strength, dimensional accuracy, machinability, application-specific needs, corrosion resistance, surface finish, cost-effectiveness, supplier reliability, and compliance with industry standards.
HSS bars are employed to create cutting tools like drills, endmills, taps, reamers, gear cutters, broaches, and tool bits. Employed in forming tools, blanking dies, and high precision tool parts too. In automotive, aerospace, and general machining applications, HSS bar stock is necessary for long-lasting tool production. These bars get cut, ground, and shaped into final tooling configurations that must have both long life and high performance when subjected to heat and mechanical stress.
We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
