Grade 409 stainless steel is a Ferritic steel that offers good mechanical properties and high-temperature corrosion resistance. It is commonly considered as a chromium stainless steel, with applications in exhaust systems of automobiles and applications that demand weldability. Grade 409 steels are also available in highly stabilized forms, such as grades S40930, S40920 and S40910. The stability of these grades is provided by the presence of niobium, titanium, or both, in the composition of steels.

Calico Metal Inc is considered as a superior supplier, stockist and manufacturer of the 409 Seamless and Welded Pipes and Tubes with national and international standards of AMS 5604. We believe in delivering excellence of service and unmatched quality of 409 to our clients from raw materials from excellent suppliers. 409 Stainless steel Seamless and Welded pipes and tubes offer high strength and hardness along with excellent corrosion resistance on the whole. 409 has been used for a variety of applications including oil field valve parts, chemical process equipment, aircraft fittings, fasteners, pump shafts, nuclear reactor components, gears, paper mill equipment, missile fittings, and jet engine parts and also petrochemical industry. Along with these applications, the 409 is known for not just the strength but also its qualities under heat treatment.
