Mourad Metals, located in Tunis, Tunisia, stands out as a reputable manufacturer and supplier of high-quality industrial steel products, catering to global markets with precision-engineered solutions. One of their flagship products is the **Tool and Die Steel S1 Bars**, crafted for the rigorous demands of toolmaking and industrial applications where toughness and shock resistance are crucial. Mourad Metals employs strict quality control measures alongside advanced steel-processing techniques to guarantee that each S1 bar adheres to stringent international standards and customer requirements. Known for their reliability and performance, Mourad Metals serves industries like automotive, manufacturing, and heavy machinery, providing S1 bars that ensure consistent mechanical integrity and durability in tough operational settings.
**Tool and Die Steel S1 Bars** are designed as shock-resisting tool steels, featuring a well-balanced alloy composition that generally includes **carbon (0.40–0.55 %)**, **chromium (1.0–1.8 %)**, **tungsten (1.5–3.0 %)**, along with **manganese**, **silicon**, and trace amounts of **molybdenum** and **vanadium** to enhance toughness and strength. This specific blend provides remarkable resistance to impact and repeated shock loading. Following the right heat treatment, S1 bars achieve **moderate to high hardness**, **high tensile strength**, and **good toughness**, making them resilient under dynamic forces and capable of resisting softening at higher temperatures.

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 scenarios that require outstanding shock resistance and durability. They are perfect for crafting **impact tools** like chisels, punches, and shear blades that need to withstand repeated mechanical shocks without breaking. S1 bars are also essential in **forging and forming dies**, where their ability to resist deformation and cracking under heavy loads is vital. Other applications include **cold forming**, where their strength and durability are put to the test in various manufacturing processes.
We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
