Product Description

Product Parameters

ASTM A250 Fe alloy-steel boiler tubes is a type of seamless steel tubes. They are divided into structural seamless tubes and high-pressure heat-resistant alloy tubes. Mainly different from the production standards and application fields. Annealing and tempering change its mechanical properties to achieve the required processing conditions. Its performance is higher than that of general seamless steel tubes. It has higher variability utilization value, alloy tube contains more Cr in chemical composition, and has high and low temperature resistance as well as corrosion resistance.
