ASTM A423 / ASME SA423 Grade 1 ERW Corten Steel Tube Heat Exchanger Tube
ASTM A423 GR.1 is a specification that covers electric-resistance welded (ERW) and seamless low-alloy steel tubes intended for use as boiler tubes， heat exchanger tubes， and condenser tubes. The tube is made from carbon-manganese steel， which gives it good weldability and toughness. It is available in a range of sizes and wall thicknesses to suit different applications， such as power generation， petrochemical， and other industries， etc. A423 Grade 1 ERW tube is often used in combination with other materials， such as carbon steel or stainless steel， to form complex piping systems.
