Phehlukwayo Metal, a well-respected manufacturer and supplier located in Cape Town, South Africa, specializes in top-notch Stainless Steel 431 Flat Bars that are built for strength, corrosion resistance, and long-lasting durability. Crafted with precision and cutting-edge technology, these bars adhere to global standards for performance and reliability. Known for their impressive toughness and high tensile strength, Stainless Steel 431 Flat Bars also boast good resistance to both corrosion and heat. Phehlukwayo Metal is committed to ensuring that every product performs exceptionally well in tough environments, catering to industries like marine, chemical, oil and gas, and manufacturing with reliable stainless steel solutions.
Stainless Steel 431 Flat Bar is a martensitic stainless steel primarily made up of iron, chromium (15–17%), nickel (1.25–2.5%), and a carefully controlled amount of carbon (up to 0.20%). This unique composition grants it excellent corrosion resistance and high mechanical strength. It offers a tensile strength of about 850 MPa, a yield strength of roughly 600 MPa, and good hardness after heat treatment. The alloy strikes a balance between good toughness and high wear resistance, and it remains magnetic in all conditions. Its well-balanced chemistry makes it ideal for applications that demand both mechanical strength and moderate corrosion resistance.
