Rashid Metals in Muscat, Oman provides Tool and Die Steel S7 Bars that are engineered for maximum toughness, reliability, and precision. S7 steel is globally recognized for its outstanding impact resistance and ability to withstand extreme shock loads, making it perfect for heavy-duty tooling applications. Each bar is crafted with strict attention to quality, ensuring consistent hardness, dimensional stability, and long-lasting performance. Manufacturers and toolmakers rely on S7 Bars to produce tools that endure repetitive stress without deforming, delivering reliable results in industries that require high performance and absolute durability.
Tool and Die Steel S7 Bars are alloyed with chromium, molybdenum, and vanadium, offering a perfect balance of hardness and toughness. This composition provides excellent shock resistance, wear resistance, and high tensile strength, allowing the steel to handle repeated impact without chipping or cracking. S7 Bars maintain dimensional stability during heat treatment and machining. Their mechanical properties include strong edge retention, good ductility, and reliable fatigue resistance. These characteristics make S7 steel ideal for applications where durability, impact resistance, and precision are critical.
