Api 5l Standard Grb X42 X52 X60 X70 Grade Yield Hr Carbon Steel Plate

Steel plate is a flat sheet of steel that is poured with molten steel and pressed after cooling. It is flat, rectangular and can be rolled directly or shears from a wide strip of steel. The steel plate is divided according to the thickness, the thin steel plate <4 mm (the thinest 0.2 mm), the medium thick steel plate 4~60 mm, the extra thick steel plate 60~115 mm.The steel plate is divided into rolling, hot rolling and cold rolling. The width of the sheet is 500~1500 mm;The width of the thickness is 600~3000 mm.According to the kinds of steel, there are ordinary steel, high quality steel, alloy steel, spring steel, stainless steel, tool steel, heat resistant steel, bearing steel, silicon steel and industrial pure iron sheet;According to the professional use, there are oil drum board, enamel board, bulletproof board and so on;According to the surface coating, there are galvanized sheet, tin plate, lead plate, plastic composite steel plate, etc.

The steels of thick plates are substantially the same as those of thin plates.In all aspects, in addition to the bridge plate, boiler plate, automotive steel, pressure vessel steel plate and multilayer high pressure vessel steel and other varieties is thick plate, some varieties of steel such as automobile beam steel plate (2.5 ~ 10 mm thick), decorative pattern plate (2.5 ~ 8 mm thick), stainless steel, heat-resistant steel and other varieties with thin cross. In addition, there is a steel plate material, not all steel plates are the same, the material is not the same, the steel plate used in the place, is not the same.

Low-alloy structural steels are mainly used in the manufacture of Bridges, ships, vehicles, boilers, high-pressure vessels, oil and gas pipelines, large steel structures, etc.Performance requirements, high strength: generally its yield strength in more than 300MPa.High Toughness: Elongation is required to be 15% ~ 20%, and the impact toughness is greater than 600kJ/m ~ 800kJ/m at room temperature.For large welded members, high fracture toughness is also required.Good welding performance and cold forming performance.Low cold and brittle transition temperature. Good corrosion resistance.
