ASTM A312 TP310S Stainless Steel Seamless Pipe for Heat Exchanger Application
ASTM A312 TP310S, as a very important high alloy austenitic heat-resistant stainless steel pipe, is renowned for its excellent high-temperature oxidation resistance and good corrosion resistance, and is widely used in various oxidative environments. According to ASTM A312 standard requirements, seamless pipes and welded pipes can be produced. For high-temperature and high-pressure working environments, seamless pipes are more commonly used and cover a wide range of nominal pipe sizes. In terms of heat treatment, ASTM A312 stainless steel pipes are often supplied in a solution annealed state (heated to ≥ 1040 ° C and then rapidly cooled), with the aim of dissolving carbides, obtaining a uniform austenitic structure, optimizing corrosion resistance, and eliminating pipe stress.

The core of the composition design of TP310S stainless steel seamless pipe lies in high chromium and high nickel. High chromium provides the tube with top-level resistance to high temperature oxidation and peeling, and has extremely high resistance to high temperature corrosion in working environments with high sulfur content. The main reason is that chromium can form a dense and stable chromium oxide protective layer in high temperature environments; The high nickel content gives TP310S stainless steel seamless pipes a stable austenitic structure, preventing harmful phase transformations, and exhibiting good resistance to reducing acid corrosion. They can maintain good ductility and creep resistance at high temperatures, while also improving their resistance to carburization.
