in modern industrial production activities, steel structure is an important basic component, and the type and weight of the steel pipe selected will directly affect the quality and safety of the building. when calculating the weight of steel pipes, carbon steel pipes are generally used. so, how to c

for the astm standard, different material with different steel grade,besides, their mechanical properties and chemical composition, metallurgical properties are all different.there are list for astm standard with different steel grade.astm a53 / a53m standard specification for pipe, steel, black and

carbon steel pipes (cs pipe) should be made of steel castings or solid round steel through perforation, and then hot-rolled, cold-rolled or cold-drawn. carbon steel pipe plays an important role in china's seamless steel pipe industry. key materials are mainly q235, 20#, 35#, 45#, 16mn. the most

carbon steel is a type of steel. it mainly refers to the steel whose mass fraction of carbon is less than 2.11% and does not contain deliberately added alloying elements. in addition to carbon, carbon steel generally contains a small amount of silicon, manganese, sulfur, and phosphorus. generally, t
