Stainless Steel Tubing Manufacturer & Supplier

Stainless Steel 321 Tubing is used for numerous industrial applications, including some: rocket and rocket motor housings; Gear; chassis components; Aerospace; extrusion dies; Diecast; heavy-duty shafts, gears and fasteners; etc. This material can produce excessive yield strengths with a simple low temperature heat treatment of to 482°C (900°F). Also it shows good ductility at high strength levels, shows excellent notch ductility and excellent weldability. It is a super alloy that has very high corrosion resistance and high temperature resistance. And so, it consists of the main components nickel, chromium and molybdenum. Applications of Stainless Steel 904L Tubing are increasing in the chemical, petrochemical, pharmaceutical and oil and gas industries. It is an incredibly strong and corrosion resistant nickel alloy commonly used for highly corrosive chemicals and acids.

We as Siddhgiri Tubes is a well-known manufacturer of SS Tubing, which is ductile and therefore can be easily shaped. It is a high temperature vacuum induction and vacuum arc melted nickel-cobalt-molybdenum low carbon alloy. It can attain yield strengths through a simple, low temperature heat treatment. It exhibits good ductility at high strength levels and is easily welded. Stainless Steel 347 Tubing is an essentially carbon-free alloy, other alloying elements include molybdenum, aluminum and titanium. The addition of chromium and molybdenum improves resistance to erosion and high temperatures. It is extremely strong, relatively soft, retains high strength and toughness, has ultra-high tensile strength, resists corrosion and crack propagation, excellent in cleaning and polishing, easily welded, etc.
