Isis Metals is a reputable manufacturer and supplier of Stainless Steel 431 Rectangular Bars, proudly based in Manila, Philippines. The company focuses on delivering high-performance stainless steel products that boast exceptional strength, hardness, and resistance to corrosion. Crafted from top-quality raw materials and utilizing precise production techniques, these rectangular bars adhere to international standards for quality and durability. Isis Metals offers Stainless Steel 431 Rectangular Bars in a variety of dimensions and finishes, serving industries like marine, aerospace, chemical, and engineering, where components face high stress, wear, and harsh environments.
These Stainless Steel 431 Rectangular Bars primarily consist of iron, chromium (15–17%), and nickel (1.25–2.5%), along with trace amounts of carbon, manganese, and silicon. This martensitic stainless steel strikes a great balance between high tensile strength (approximately 850–1000 MPa) and solid corrosion resistance. The alloy showcases remarkable hardness, toughness, and resistance to both chemical attacks and oxidation. It excels in settings that demand high mechanical strength and moderate corrosion resistance, especially when heat-treated or tempered for improved properties.
