One of the top producers and suppliers of premium stainless steel products is Vinit Stainless, which has its headquarters in Chennai, India. We offer a wide variety of stainless steel materials in one location, with an emphasis on quality, dependability, and durability. Our stainless steel 409 sheets and plates, which are renowned for their outstanding performance at high temperatures and high corrosion resistance, are specifically made for automotive, industrial, and chemical applications. By providing specialized solutions, first-rate customer support, and affordable prices, we take great satisfaction in precisely and effectively meeting the changing demands of various industries.
The ferritic stainless steel alloy known as Stainless Steel 409 is primarily made up of 10.5–11.75% chromium, with trace amounts of silicon, carbon, and manganese. It has outstanding resistance to oxidation and corrosion, especially at high temperatures. The alloy usually possesses moderate hardness, good durability, and a tensile strength between 450 and 600 MPa. Superior formability, scale resistance at high temperatures, and weldability are important benefits. Because of its mechanical and chemical characteristics, it is an affordable option for industrial applications that demand long-term dependability in addition to performance.
