Kencotube is Manufacturer and Exporter for Stainless Steel 321 Pipe Fittings, which are stabilized against carbide precipitation and designed for operation within the damaging temperature range where carbide precipitation develops. Titanium addition in Stainless Steel 321 Butt Weld Fittings eliminates the formation of chromium carbides at the grain boundaries by tying up the carbon and nitrogen as titanium carbides or nitrides. In Stainless Steel 321 Butt Weld Pipe Fittings, the carbon merges specially by means of titanium to make innocuous titanium carbide, parting the chromium in solution to uphold complete corrosion resistance. SS 321 Butt Weld Pipe Fittings is a common austenitic 18/8 stainless steel alloy, with the addition of titanium. SS 321 Pipe Fittings has better high temperature properties than SS 304 or SS 304L.
SS 321 Butt Weld Fittings is generally used for parts which are intermittently heated up to 1500 Degree F, where for continuous service the alloy is good to 1650 Degree F. Alloy 321 Butt Weld Pipe Fittings is basic type 304 modified by adding titanium in an amount at least 5 times the carbon plus nitrogen contents. Alloy 321 Butt Weld Fittings has high carbon for better high temperature creep properties. Alloy 321 Pipe Fittings is widely used in high temperature environments of up to 900 Degree C. 321 Stainless Steel Pipe Fittings has good welding and forming capabilities and is widely used in operating temperature environments in excess of 500 Degree C.
