ASTM A423 Grade 1 Weathering Steel Pipe covers minimum wall thickness, seamless and electric resistance welded, low alloy steel pipes. ASTM A423 Grade 1 pipe is a type of carbon steel called weathering steel. The special thing about this material is that it forms an oxide layer under severe weather conditions. The oxide layer formed on the surface is called patina. The main application areas of ASTM A423 Grade 1 alloy steel pipe include equipment such as economizers, air preheaters, heat exchangers and evaporators, which usually operate in environments with high sulfur flue gas.
