20# steel

Seamless steel pipe and welded steel pipe are two common types of steel pipes, which have significant differences in manufacturing process, performance, application areas, etc. Seamless steel pipe manufacturing process: Seamless steel pipe is made directly from a whole piece of metal through processes such

Petroleum Oil cracking tubes are seamless tubes for furnace tubes, heat exchanger tubes and pipelines in oil refineries. In the process of oil refining, they are mainly used in cracking units. Cracking is a chemical process that breaks down long-chain hydrocarbon molecules into shorter molecules

20# steel is a high-quality low-carbon steel, cold extruded carburized hardened steel with low strength, good toughness, plasticity and weldability, tensile strength of 355~500Mpa, and elongation of 24%. 20# is used for metal structures and components working at -40℃ to +450℃. Hot-rolled and forged long
