ASTM A269 TP321 stainless steel tube is a stainless steel with titanium (Ti) added to 304 stainless steel, which improves the resistance of stainless steel TP321 welded tube to intergranular corrosion in high temperature environment, especially after welding or in heat-affected areas, which can significantly reduce or avoid the occurrence of intergranular corrosion.
ASTM A269 TP321 stainless steel heat exchanger tube has higher heat resistance and stress corrosion cracking resistance, and can maintain stable performance at high temperature (up to 816°C).
A269 TP 321 Round Welded Tubes usually have an outer diameter of 6.35 mm to 101.6 mm (1/4" to 4"), and a wall thickness of 0.5 mm to 6.0 mm.
