A209 alloy pipe is an American standard alloy steel pipe. It not only has high oxidation resistance and high temperature steam corrosion resistance, but also has good impact toughness, high and stable long-lasting plasticity and thermal strength properties.
When the service temperature is lower than 620°C, its allowable stress is higher than that of austenitic stainless steel. It is mainly used for super boiler tubes, high-temperature superheaters, reheater steel tubes, high-temperature headers and steam pipes. It can also be used as nuclear power heat exchangers and petroleum cracking unit furnace tubes.
