Maduka Metals, a reputable manufacturer and supplier located in Abuja, Nigeria, specializes in high-quality Tool and Die Steel S1 Bars that are designed for exceptional impact resistance and toughness. These bars are crafted using cutting-edge metallurgical techniques to guarantee consistent quality, precision, and reliability. Renowned for their outstanding performance in shock-loading scenarios, S1 Bars from Maduka Metals are perfect for industries that require robust tooling materials. With a strong focus on innovation, quality assurance, and customer satisfaction, the company delivers Tool and Die Steel S1 Bars that provide remarkable strength, wear resistance, and performance even in the toughest industrial environments.
The composition of Tool and Die Steel S1 Bars includes carbon (approximately 0.5%), silicon (0.3%), chromium (3%), molybdenum (1.1%), and tungsten (2.5%), along with small amounts of vanadium to enhance hardness. This well-balanced mix results in excellent shock resistance, ductility, and wear resistance. Mechanically, S1 steel boasts a tensile strength of about 850–1000 MPa in its annealed state and can achieve a hardness of up to 58 HRC after heat treatment. Its capacity to maintain stability and strength under repeated impacts and thermal stress makes it an ideal choice for heavy-duty tool and die applications.

When choosing Tool and Die Steel S1 bars, consider hardness, wear resistance, toughness, machinability, heat treatment capabilities, and the specific requirements of the application to ensure optimal performance and durability.
Tool and Die Steel S1 bars resist corrosion due to their alloy composition, which includes elements like chromium and molybdenum. These elements form a protective oxide layer, enhancing resistance to oxidation and rust.
Tool and Die Steel S1 Bars are extensively utilized in the manufacturing of tools and components that need to endure significant impact and mechanical shock. They are frequently used in the creation of chisels, punches, hammers, shear blades, and cold-forming tools. In the automotive and construction sectors, S1 Bars are employed for forging dies and impact-resistant tooling. Their high toughness and wear resistance also render them suitable for mining tools and cutting instruments. Furthermore, Tool and Die Steel S1 Bars are highly regarded in industrial machinery for their ability to perform reliably under continuous stress and challenging working conditions.
We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
