Sachiya Steel International is one of the Leading Manufacturer And Exporter of Stainless Steel 321 Buttweld Fittings, which is non-magnetic and offered in different sizes. This Stainless Steel 321 Butt Weld Fittings is often used in super-heater and afterburner parts, along with compensators and expansion bellows. Our Stainless Steel 321H Butt Weld Fittings is used extensively for applications where the addition of titanium and its stabilizing effect as a carbide forming element allows it to be welded and / or used within the carbide precipitation range 430 Degree C – 870 Degree C without the risk of inter-granular corrosion.
This Stainless Steel 321 Pipe Fittings is well known in reference literature and more information can be obtained in this way. Our Stainless Steel 321H Pipe Fittings is also used in refinery equipment and high temperature chemical process equipment. Titanium addition in this Stainless Steel 321 Elbow is made to reduce or eliminate chromium carbide precipitation – resulting from welding or exposure to high temperatures.
