Forged Carbon Steel Pipe Flanges for Industrial Piping

Carbon steel flanges are produced from a variety of steel options containing anywhere from 0.05% to 2.1% carbon, which directly affects the strength, hardness, ductility, and weldability. The chemical composition of carbon steel (with the absense of chromium, nickel, molybdenum, and other elements) makes it both cost-effective and versatile.  One of the advantages of carbon steel is that it can be easily machined, welded, and heat treated, which allows manufacturers to tailor flanges for a wide range of applications. As the carbon content increases, the steel can be made stronger and harder, though this also reduces ductility and weldability. Grades like ASTM A36 (mild/low carbon steel plate flange) and A105 (medium carbon, forged flanges) are most common in industrial piping systems.   Material Standards 1. Material Specification Standards ASTM A105 – The most common grade used for forged carbon steel flanges in ambient and high-temperature pressure systems. ASTM A36 / Q235 – Des…
