ASTM A182 F51, F53, F55, and F60 are different grades of duplex and super duplex stainless steel defined by the ASTM A182 standard for forged and rolled alloy flanges, fittings, and other components used in high-pressure, high-temperature service.

GX5CrNiMo19-11-2 is a popular austenitic stainless steel for casting purposes; it is an austenitic corrosion-resistant casting steel. GX5CrNiMo19-11-2 is defined in standards EN 10213, EN 10283, and ISO 11972, with the EN designation being 1.4408.

ASME SA789 UNS S32205 duplex steel U-bend boiler tubes are U-shaped tubes made of 2205 duplex stainless steel in accordance with ASME SA789 standards. They are suitable for corrosion-resistant, high-strength applications in boilers, heat exchangers, and other demanding industries.

ASTM A269 TP316L stainless steel seamless coiled tubing is a pipe that meets ASTM A269 standards and is suitable for general corrosion-resistant as well as low-temperature and high-temperature applications.

ASTM B677 is a ASTM International standard specification that covers seamless, cold-worked or hot-finished nickel alloy pipe and tube intended for general corrosive service. It defines the requirements for materials designated by various UNS numbers, such as UNS N08904 (904L Stainless Steel), UNS N08925, and UNS N08926, which offer enhanced resistance to corrosion due to their specific alloy composition.

ASME SA213 specification covers seamless ferritic and austenitic steel boiler, superheater, and heat exchanger tubes. It defines the chemical composition, mechanical properties, and dimensional requirements of the tubes
