3/32” 309/309S Stainless Steel Coil

Product Overview

High-temperature resistant 309 stainless steel coil is specifically engineered for extreme heat applications, making it a crucial material for industries that require durable and corrosion-resistant steel under high temperatures. With excellent oxidation resistance up to 1150°C, 309 stainless steel coil is widely used in the manufacturing of furnace parts, thermal processing systems, and heat treatment equipment. It is available in various forms, including 309 stainless steel slit coil, which is designed for precision engineering, and stainless steel tubing coil, which is ideal for industrial piping and heat exchange systems.

The unique properties of 309 stainless steel coil make it a preferred choice for industries such as aerospace, automotive, chemical processing, and power generation. Due to its high chromium and nickel content, this stainless steel grade exhibits superior resistance to scaling and oxidation at high temperatures, making it more reliable than standard stainless steel grades for high-heat applications.
