ASME SA213M / SA213 T9 is the standard applicable to Seamless Alloy-Steel Boiler, Superheater, and Heat-Exchanger Tubes.

EN 10083-2 C45E‌ is a medium carbon steel with high strength and hardness. It is suitable for manufacturing some mechanical parts that require high strength and wear resistance, such as shafts, gears, hubs, etc.

ASTM A790 UNS S32750 seamless pipes are mainly used in submarine pipeline laying, shipbuilding and offshore gas field exploitation where high strength and high corrosion resistance are required.

A519 seamless tubing is commonly used in applications requiring machining, heat treating, close tolerances, smooth finishes, and/or definite physical properties.
