Neith Metals, based in Cairo, Egypt, has built a solid reputation as a reliable manufacturer and supplier of high-quality Tool and Die Steel S1 Bars. These bars are celebrated for their exceptional toughness and wear resistance, making them perfect for high-impact situations. Thanks to their state-of-the-art production facilities and rigorous quality control, Neith Metals ensures that their products meet international standards for precision tooling and die applications. Their dedication to innovation and dependability has made them a go-to choice for industries in need of durable, performance-oriented tool steels for challenging manufacturing environments.
Tool and Die Steel S1 Bars are primarily made up of carbon (0.45–0.55%), silicon (0.20–1.00%), manganese (0.20–0.80%), chromium (3.00–3.50%), and molybdenum (0.20–0.50%), along with small amounts of vanadium and tungsten. This combination gives them excellent impact resistance, good hardenability, and dimensional stability. After heat treatment, S1 steel typically achieves a hardness range of 56–60 HRC, with tensile strength surpassing 1600 MPa. It also boasts high toughness and shock loading resistance, making it an ideal choice for tools that face repeated impact and abrasion.

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.
Industries that require tools capable of withstanding repeated shock and impact extensively use Tool and Die Steel S1 Bars. You’ll find them in applications like cold chisels, punches, hammers, shear blades, and dies for metal stamping and forming operations. Their outstanding toughness also makes them perfect for impact tools and cold-work dies that need to resist cracking and chipping. Moreover, S1 bars are utilized in the production of forging dies and cutting tools, where both strength and resilience are crucial. Their versatility guarantees reliable performance in demanding industrial tooling applications.
We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
