Hot Rolled usage of hardox 400 steel for oil tank

A633GrD steel plate is suitable for normalized high-strength low-alloy structural steel plate for tower connection or source bolt connection structure. A633GrD steel plate should be normalized: heat the steel plate to a suitable temperature that can produce austenite structure but does not exceed 1700F [925℃], and keep it at this temperature for a period of time, so that the entire usage of HARDOX 400 steel plate can be uniformly heated, and then left in the air Cool with medium.In recent years, in line with the development trend of iron and usage of HARDOX 400 steel steel industry at home and abroad, we have accelerated the transformation of development mode, promoted structural adjustment, and formed a rich product series of medium and thick plates, hot rolled steel coils, profiles, steel pipes, etc., which usage of HARDOX 400 steel are widely used in automobiles, long-span bridges, railways, machinery, ocean and so on fields. Meanwhile, we also provide deep processing for the steel materials."Mirror" refers to the surface state of usage of HARDOX 400 steel stainless steel, which is usually 8K in the industry. The common mirror stainless steel on the market is divided into 6K, 8K and 10K, which are general polishing, 6K, 8K fine grinding and 10K super fine grinding effect. The same thickness generally has no big difference, 10K mirror is brighter; the thicker the thickness, the better the effect, and the higher the processing cost.With the increase of carbon content in the steel material, the yield point and tensile strength increase, but the plasticity and impact decrease. When the carbon content is more than 0.23%, the welding performance of the steel material becomes worse. Therefore, the carbon content of low alloy structural steel used for welding is generally less than 0.20%. The high carbon content can also reduce the atmospheric corrosion resistance of steel material, and the high carbon steel in the open air is easy to rust; in addition, carbon can increase the cold brittleness and aging sensitivity of usage of HARDOX 400 steel etc. steel material.We should focus on the main problems to be solved and pay attention to efficiency. After receiving the user's quality objection report data, the possible causes, responsible units, compensation amount, etc. of the problem shall be judged based on experience. To have a clear service plan, to be clear about what your main problem is, what technical support is needed, these should be prepared.
