ASTM A213 TP316L Stainless Steel Seamless Boiler Tube

ASTM A213 is a standard number developed by the American Society for Testing and Materials, which is specifically applicable to seamless ferritic and austenitic alloy steel pipes for boilers, superheaters, and heat exchangers. This means that steel pipes under this standard are designed to withstand high pressure and high temperature environments. TP316L is a low-carbon austenitic stainless steel grade with excellent corrosion resistance and outstanding resistance to chloride pitting corrosion.

 

ASTM A213 TP316L stainless steel heat exchanger tubes are a molybdenum-containing austenitic stainless steel. Compared to traditional chromium-nickel austenitic stainless steels (such as 304), 316L stainless steel offers greater resistance to general corrosion, pitting, and crevice corrosion. In addition to excellent corrosion resistance and strength, Alloy 316 and 316L chromium-nickel-molybdenum alloy tubes also possess the excellent processing and formability typical of austenitic stainless steels. 316L stainless steel boiler tubes also exhibit higher creep strength, rupture stress, and tensile strength at elevated temperatures. The recommended operating temperature range is -425°F to 1,200°F (-255°C to 605°C).
