Heat Exchanger Tube, ASME SA213 TP444 (UNS S44400) Ferritic Stainless Steel Seamless Tube
Heat Exchanger Tube, ASME SA213 TP444 (UNS S44400) Ferritic Stainless Steel Seamless Tube
ASME SA213 TP444 Stainless steel seamless tube is a type of stainless steel which has excellent corrosion and oxidation resistance. This steel contains molybdenum, nitrogen and copper, which increases strength and improves weldability. It is ideal for high-temperature applications such as piping systems. In addition, it has excellent pitting corrosion resistance and good formability because of its high chromium content.
