The steel plate used for containers and pressure vessel has to bear different pressures and strengths due to the manufactured containers. The normal pressure is generally 31.4MPa or higher; the working temperature is usually between -20 ℃ -450 ℃, and sometimes lower than -20 ℃. According to the working conditions and processing technology of the container, the marine grade GL-E36 hull steel plate, steel plate used for the container must have good cold bending and welding performance. Besides, it should have good plasticity and toughness, high temperature short-term strength or long-term strength performance.
If the chromium content in marine grade GL-E36 hull steel plate alloy steel reaches about 12%, dense chromium oxides will be formed on the surface of the steel, which will greatly improve the corrosion resistance of steel in oxidizing media. Chromium, aluminum, silicon and other elements can improve the oxidation resistance of steel and the corrosion resistance of high-temperature gas, but excessive aluminum and silicon will deteriorate the thermoplasticity of steel.
Chemical composition of 42CrMo seamless steel pipe: C: 0.38-0.45, Si: 0.17-0.37, Mn: 0.50-0.80, Cr: 0.90-1.20, Mo: 0.15-0.25, V: 0.15-0.30. Mechanical properties of 42CrMo seamless steel pipe: tensile strength: 1080 MPa, yield strength: 930 MPa, elongation after fracture: 12%, reduction of area: 45%, impact energy: 63J. Due to the effect of carbon and chromium content, marine grade GL-E36 hull steel plate, 42CrMo seamless steel pipe has better strength and hardenability, higher fatigue strength and resistance to multiple impact after quenching and tempering, good impact toughness at low temperature and no obvious temper brittleness. It is generally used after quenching and tempering.
As steel transportation belongs to the transportation of major parts, so in the process of transportation, modern logistics technology, such as centralized transportation, information technology, is a bit out of place. Based on the current situation of China's marine grade GL-E36 hull steel plate steel transportation industry, highway transportation is a way of transportation that many enterprises often choose. Naturally, its business volume also accounts for more than 50% of the whole marine grade GL-E36 hull steel plate steel transportation industry.
