Sabra Metals, located in Amman, Jordan, is a dependable manufacturer and supplier of high-performance Tool and Die Steel S7 bars, serving industries that demand exceptional impact resistance and durability. With a strong focus on quality assurance and advanced processing standards, Sabra Metals delivers S7 bars engineered for tough tooling environments where shock loads and frequent impacts are common. The company’s commitment to precision, consistency, and customer support makes it a trusted partner for toolmakers, fabricators, and industrial manufacturers seeking reliable steel solutions for high-impact applications.
Tool and Die Steel S7 bars feature a balanced composition with medium carbon content and significant amounts of chromium and molybdenum, giving them superior shock resistance and excellent toughness. This alloy maintains good wear resistance while offering high impact strength, making it ideal for tools exposed to repeated force. After proper heat treatment, S7 typically achieves hardness levels around 54–56 HRC while retaining stability and ductility. Its ability to resist chipping, cracking, and deformation makes S7 a versatile choice for demanding tool and die applications.
