JIS G3463 stainless steel pipe is used for internal and external heat exchange of the pipe. Its application areas are boiler superheater tubes, heat exchanger tubes, condenser tubes and other chemical and petroleum industries. It is not designed for heating furnace tubes. According to the manufacturing method, there are seamless steel pipes and welded stainless steel pipes (automatic arc welding, laser welding or resistance welding).
ASTM A790 S31803/S32205 Duplex Stainless Steel Pipe Duplex stainless steels are extremely corrosion resistant, work hardenable alloys. Their microstructures consist of a mixture of austenite and ferrite phases. As a result, duplex stainless steel display properties characteristic of both austenitic and ferritic stainless steel. This combination of properties can mean some compromise when compared with pure austenitic and pure ferritic grades. Duplex stainless steels are in most cases, tougher than ferritic stainless steel Strengths of duplex stainless steel can in some cases be double that for austenitic stainless steel.
Conclusion ASTM A358 (ASME SA358) chromium nickel stainless steel pipes are specifically designed for high-temperature and corrosive environments, offering versatility and reliability across various industries. Their availability in multiple classes allows for customization based on specific welding and inspection needs, ensuring they meet rigorous service demands.
