Dhruv Metals, a reputable manufacturer and supplier located in Hyderabad, India, specializes in high-quality Stainless Steel 446 Square Bars and Rods, perfect for extreme temperatures and corrosive environments. Crafted with precision and adhering to international standards, these square bars and rods boast impressive resistance to oxidation, sulfidation, and thermal fatigue. Dhruv Metals is committed to providing reliable solutions for industries like heat treatment, power generation, and chemical processing, where durability and stability at high temperatures are crucial for long-lasting performance.
The Stainless Steel 446 Square Bars and Rods are made from a ferritic stainless steel alloy that contains 23–27% chromium, along with very low carbon content and small amounts of silicon and molybdenum. This unique composition ensures exceptional resistance to high-temperature oxidation and corrosion. Typically, they exhibit mechanical properties such as a tensile strength ranging from 485–620 MPa, a yield strength of about 275 MPa, and commendable creep resistance. The square profile not only enhances structural strength but also makes them ideal for fabrication and machining in thermal processing and industrial settings.
