Jis Standard Ss400 Steel Grade Yield Strength And Tensile Strength Hr Carbon Steel Plate

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.
