Neith Metals, based in Cairo, Egypt, stands out as a leading manufacturer and supplier of top-notch stainless steel products, with a particular focus on Stainless Steel 431 Rectangular Bars. The company has built a solid reputation for delivering precision-engineered materials that are not only corrosion-resistant but also incredibly durable, all while adhering to international quality standards. Thanks to their cutting-edge production technology and rigorous quality assurance processes, Neith Metals guarantees exceptional product performance and reliability. Their Stainless Steel 431 Rectangular Bars are crafted for outstanding strength, toughness, and wear resistance, making them perfect for demanding industrial, mechanical, and structural applications across various engineering fields.
Stainless Steel 431 Rectangular Bars are martensitic stainless steel alloys celebrated for their impressive strength, hardness, and moderate resistance to corrosion. Typically, their chemical makeup consists of 16–18% chromium and 0.2–0.25% carbon, along with trace amounts of nickel, manganese, and silicon. These bars can achieve tensile strength up to 850 MPa, yield strength around 450 MPa, and hardness levels between 220–260 HB. They respond exceptionally well to heat treatment, which boosts their toughness and wear resistance, making them ideal for heavy-duty components that demand both mechanical strength and corrosion resistance.
