ASTM A815 S32750 Duplex Steel Fitting Elbow 90 Degree Long Radius Buttweld B16.9
ASTM A815 standard is applicable for the manufacture, testing, and inspection of duplex stainless steel fittings used in high temperature, high pressure, and corrosive environments. These fittings include but are not limited to elbows, flanges, tees, pipe caps, and other types. This standard covers various duplex stainless steel materials such as UNS S31803, S32205, S32750, etc., and different materials are suitable for different environmental conditions. For example, S31803 (ferritic austenitic stainless steel) is suitable for low-temperature environments, while S32205 is more suitable for high-temperature and high-pressure environments.
