Carbon steel Grade C40 is a good quality carbon structural steel with high plasticity in cold deformation. Its metallographic structure is pearlite + ferrite, with a simple heat treatment process, usually direct cutting or forging normalizing, mainly used for common structural parts, connecting parts or stamping parts, or for the use of carburizing steel. The EN 10083-2 steel pipe were originally intended for the production of quenched and tempered conditions, they could also be made available in a normalized condition. Grade C40 Steel Pipe is comparable to low carbon steel pipes with the content of carbon ranges between 0.30 to 0.60% and 0,50 – 0,80 Mn. WLD steel supplies carbon steel pipe C40 seamless steel tubes manufactured in quenching and tempering process with various sizes and equivalent material for general applications.
