ASTM A790 is the Standard Specification for Seamless & Welded Ferritic/Austenitic Stainless Steel Pipe. Read more at Langley Alloys.

ASTM A240 is a standard specification for chromium and chromium-nickel stainless steel plates, sheets, and strips used in pressure vessels and general applications. It defines the chemical composition, mechanical properties, and other requirements for various stainless steel grades, ensuring they meet specific corrosion resistance and strength standards. This includes common grades such as 304, 316, and various duplex stainless steels.

Application fields 304 stainless steel is widely used in food, pharmaceutical, chemical, and construction fields. 409 stainless steel is mainly used in automotive, manufacturing, and construction fields, especially in automotive exhaust systems.

1.4408 is a cast stainless steel that contains molybdenum, which provides good resistance to general corrosion, but 1.4541's titanium stabilization makes it more resistant to intergranular corrosion, particularly after welding or exposure to high temperatures.

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.
