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.
