Renine Metalloys is a known supplier and manufacturer of SS 321 / 321H Pipe Fittings, which has high carbon (.04 - 10) for better high temperature creep properties. Stainless Steel 321 Pipe Fittings is often used for Aerospace – piston engine manifolds, Expansion Joints, Chemical Processing, and so on. If hot forming is required, once again, Stainless Steel 321 Butt Weld Fittings should be considered as an alternate selection. Do not work 321 Stainless Steel Pipe Fittings at temperatures below 1700 Degree F (927 Degree C). Titanium is added to the composition of 321 Stainless Steel Butt Weld Fittings to suppress grain boundary chromium carbide precipitation and reduce susceptibility to inter - granular corrosion. Alloy 321 Pipe Fittings is readily welded by most standard processes, along with very ductile and forms easily.

Stainless Steel 321/321H Pipe Fittings

Stainless Steel 321H Pipe Fittings has excellent weldability by all standard fusion methods, both with and without filler metals. Stainless Steel 321H Butt Weld Fittings is also used for Thermal oxidizers, High temperature chemical process equipment, Refinery equipment, and so on. However local depletion within the weld area of 321H Stainless Steel Butt Weld Fittings can still be a problem leading to some inter - granular corrosion if later exposed to severe corrosive conditions. When MAG welding in these 321H Stainless Steel Pipe Fittings is carried out with wire, a power source with pulse current may be necessary to obtain good weldability.
