Maduka Metals, a well-respected manufacturer and supplier located in Abuja, Nigeria, is known for its top-notch **Stainless Steel 17-7 PH Hex Bars and Rods**. These bars are crafted to deliver outstanding strength, hardness, and resistance to corrosion, all while ensuring good formability and fatigue properties. By utilizing high-quality raw materials and cutting-edge technology, Maduka Metals guarantees precision, durability, and adherence to international standards. The 17-7 PH (Precipitation Hardening) stainless steel is particularly famous for its capacity to achieve impressive mechanical strength through heat treatment, making it perfect for demanding industrial and aerospace applications.
**Stainless Steel 17-7 PH Hex Bars and Rods** mainly consist of **iron**, with **16–18% chromium**, **6.5–7.75% nickel**, and **0.75–1.5% aluminum**, along with trace amounts of **manganese**, **silicon**, and **carbon (≤0.09%)**. The precipitation-hardening process boosts tensile strength up to **1310 MPa** while still maintaining good ductility and corrosion resistance. These bars show remarkable oxidation resistance, high yield strength, and minimal distortion during heat treatment, making them ideal for precision-engineered components.
