Dhruv Metals is a reputable manufacturer and supplier located in Hyderabad, India, focusing on top-notch Stainless Steel 431 Square Bars and Rods. Renowned for their durability and exceptional finish, our SS 431 products are crafted with precision to adhere to international standards. Stainless Steel 431, a type of martensitic stainless steel, is made up of chromium and nickel, providing outstanding corrosion resistance and mechanical strength. With years of experience in the industry, Dhruv Metals is dedicated to offering reliable stainless steel solutions for demanding industrial applications both in India and around the globe.
The composition of Stainless Steel 431 Square Bars and Rods primarily includes chromium (15.0–17.0%) and nickel (1.25–2.50%), along with carbon (up to 0.20%), manganese, and silicon (both up to 1.0%), as well as phosphorus (up to 0.040%) and sulfur (up to 0.030%). In terms of mechanical properties, these bars boast a tensile strength ranging from 850 to 1000 MPa, a yield strength of at least 600 MPa, an elongation of 15% or more, and a Brinell hardness of up to 260 HB. These characteristics endow SS 431 with high tensile strength, good toughness when tempered, and resistance to wear and fatigue, making it perfect for heavy-duty applications.
