The seamless carbon steel pipe for ships (gb5213-85) is the seamless carbon steel pipe for the manufacture of class I pressure pipe system, class II pressure pipe system, boiler and Superheater of ships. HR coil Q235 pickled steel coil. The working temperature of carbon steel seamless pipe wall shall not exceed 450 ℃, and that of alloy steel seamless pipe wall shall exceed 450 ℃.
Strip steel is a kind of steel plate with thin thickness, narrow width and long length. Strip steel can be made of common carbon steel, carbon structural steel, spring steel, tool steel, stainless steel, etc. Strip steel has the advantages of high dimensional accuracy, good surface quality, easy processing and material saving. There are many kinds of strip steel, HR coil Q235 pickled steel coil. Hot rolled steel strip is mainly used for cold-rolled billets, cold-formed steel billets, welded steel pipe billets, manufacture of bicycles and small hardware products.
The hardness and impact toughness of precipitation-strengthened wear plates, HR coil Q235 pickled steel coil are also improved. For example, the hardness of the wear-resistant plate after precipitation strengthening is 230-300 HBW, and the impact toughness is 140-180. More importantly, the improvement of the above indicators does not bring about a significant decrease in plasticity. The performance of the wear-resistant plate after water quenching at 1100℃, first holding at different temperatures in the middle temperature zone, and then water quenching at 970℃. With the increase of the holding temperature in the middle temperature zone and the extension of the holding time, the number of carbides in the steel increases, and the precipitation strengthening effect increases, resulting in an increase in hardness.
The chemical composition of 20CrMo steel pipe is 0.17-0.24, Si: 0.17-0.37, Mn: 0.40-0.70, Cr: 0.80-1.10, Mo: 0.15-0.25. Mechanical properties of 20CrMo steel pipe: tensile strength 410 Mpa; yield strength: 265mpa; elongation after fracture: 24; reduction of area: 60; impact absorption energy: 110J. 20CrMo steel pipe belongs to alloy structure steel pipe, which has high thermal strength, good high-temperature strength, good machinability, medium cold bending plasticity, high hardenability and good welding performance at 500-520℃. HR coil Q235 pickled steel coil, 20CrMo steel pipe is generally used in quenching and tempering state.
