Sahil Metals, located in Riyadh, Saudi Arabia, is a reputable manufacturer and supplier known for its high-performance industrial metals. With a strong focus on quality and reliability, Sahil Metals provides a diverse range of products, including Tool and Die Steel S1 Bars, tailored to meet the rigorous demands of various manufacturing sectors. Committed to precision engineering and customer satisfaction, Sahil Metals has earned its place as a go-to choice for industries throughout the region. Our S1 tool steel bars are perfect for applications that require exceptional impact resistance and durability, ensuring they perform reliably even in the toughest working conditions.
Tool and Die Steel S1 Bars are made from tungsten-chromium shock-resisting steels. Their typical composition includes: Carbon (0.5–0.6%), Chromium (1.2–1.6%), Molybdenum (0.2–0.5%), Silicon (0.2–1.0%), and Vanadium (0.2–0.5%). S1 steel is known for its excellent toughness and high impact resistance, even in low temperatures. It boasts a tensile strength range of 1400–2000 MPa and good hardenability. This steel can be oil-hardened and retains its structural integrity under heavy shock loads. Additionally, it offers decent wear resistance and is often tempered to enhance its mechanical properties based on the intended application.

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 find extensive use in industries where tools face high shock or impact loads. They are commonly used for cold working punches, chisels, shear blades, driver tools, rivet sets, and pneumatic tools. Thanks to their remarkable toughness and resistance to sudden impacts, S1 bars are ideal for tools involved in forging, stamping, and cutting operations. Their durability also makes them well-suited for tools that experience rapid temperature fluctuations or operate in low-temperature environments.
We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
