By leveraging advanced technology and rigorous quality control processes, they deliver exceptional stainless steel products that excel even in the toughest conditions, earning them a solid reputation in Nigeria’s metal and alloy sector.
Stainless Steel 420 Round Bars and Rods are martensitic stainless steels, primarily made up of chromium (12–14%), carbon (0.15–0.40%), along with trace elements like manganese, silicon, and nickel. This unique blend provides remarkable hardness, strength, and a decent level of corrosion resistance. The material boasts a tensile strength ranging from 700 to 850 MPa and demonstrates good impact toughness when properly heat-treated. These mechanical properties make it perfect for applications that require wear resistance and durability, such as tools, shafts, and surgical instruments. Plus, it can be polished to a brilliant finish, enhancing both its look and functionality.
