YUHONG GROUP Orders ASTM A213 TP304H Stainless Steel Seamless Straight Tubes

ASTM A213 is a US standard specification for seamless austenitic and ferritic alloy steel tubes intended for boiler, superheater, and heat exchanger applications. TP304H is a high-temperature grade austenitic stainless steel under this standard, specifically designed for long-term service under high-temperature conditions. It is widely used as heat exchange tubes in heat exchangers and air coolers, as well as pipelines for conveying high-temperature fluids.
