Neith Metals stands out as a top-notch manufacturer and supplier located in Cairo, Egypt, specializing in high-quality Tool and Die Steel S7 Bars. These bars are celebrated for their remarkable toughness, shock resistance, and versatility, making them perfect for both cold and hot work applications. At Neith Metals, every S7 Bar is crafted with meticulous attention to quality, utilizing advanced metallurgical processes to ensure they meet international standards. The company’s commitment to performance, precision, and customer satisfaction has established it as a reliable partner for industries that need durable and dependable tool steels for high-impact and heavy-duty tooling tasks.
Tool and Die Steel S7 Bars generally consist of carbon (0.45–0.55%), chromium (3.00–3.50%), molybdenum (1.30–1.80%), silicon (0.20–1.00%), and manganese (0.20–0.80%). This specific blend creates a unique combination of strength, toughness, and wear resistance. After heat treatment, S7 steel reaches a hardness of 54–58 HRC and showcases excellent impact resistance along with good dimensional stability. It retains its properties whether hardened in air or oil, making it ideal for tools that face repeated impacts and high stress.
