High Temperature Resistant ASTM ASME SA213 ASTM A213 TP304H Austenitic Seamless Tube for Industrial Heat Exchanger
YUHONG GROUP we are one of the leading manufacturers of stainless steel tubes for heat exchanger .With the development more than 35 years' development we have exported more than 85 countries all around the world .Yuhong brand products ,with competive price and delivery ,won the great praise among our clients .
Heat Exchanger Tube Specification:
ASTM A213 TP304H (UNS S30409) is a premium austenitic seamless stainless steel tube engineered for high-temperature, high-pressure service in boilers, superheaters, reheaters, and heat exchangers. As a carbon-controlled variant of TP304, TP304H features a higher carbon range (0.04–0.10%) that delivers superior creep-rupture strength at temperatures above 538°C (1000°F), making it the top choice for power generation and industrial thermal equipment. Manufactured via seamless hot finishing or cold drawing and solution-annealed, it ensures exceptional structural integrity, corrosion resistance, and long-term reliability under extreme operating conditions.
