Stainless Steel Tube Information

Stainless tube can be used for a variety of applications from handrails to car mufflers. Manufacturers prefer stainless steel as it has a resistance to high levels of heat and destructive elements such as salt. Tubing made out of materials such as galvanized steel or copper may become eroded or rusty with some applications, as they have a much shorter life span compared to stainless steel. Armour Alloys helps many stainless manufacturers decide what grades and materials to use for their unique manufacturing job.

409

General Characteristics

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.
