Five causes of cracks in ship construction use A131 AH32 structural steel during quenching

The rise and fall of ship construction use A131 AH32 structural steel, steel pipe price will be affected by many factors, such as market demand. If the construction of real estate industry, basic road construction and so on industries is booming, the sales volume of steel pipes will be very good, and the market supply will gradually increase. The market demand has a very important guiding significance for ship construction use A131 AH32 structural steel, steel pipe manufacturers, dealers and agents in many regions.

The addition of Ca element in steel such as ship construction use A131 AH32 structural steel can refine grain size, partly desulphurize and change the composition, quantity and morphology of non-metallic inclusions. It is similar to that of adding rare earth in steel. It can improve the corrosion resistance, wear resistance, high temperature and low temperature resistance of steel, improve the impact toughness, fatigue strength, plasticity and welding performance of the steel, and increase the cold heading, shock resistance, hardness and contact endurance strength of the steel.

On October 16, 2019, the Board of Directors of the World Steel Association (worldsteel) elected the following new officers for 2019/2020 at the worldsteel General Assembly in Monterrey. The new ship construction use A131 AH32 structural steel officers are elected for a one-year period: Chairman - YU Yong, Chairman, HBIS Group Co., Ltd. Vice Chairman - Sajjan JINDAL, Chairman and Managing Director, JSW Steel Limited.

EH500 steel plates and EH550 steel plates are both ultra-high-strength structural steel plates for ships and oceans. The addition of microalloying elements can not only improve the strength, compensate for the strength loss caused by the reduction of carbon equivalent, but also improve the welding performance, mechanical properties and process performance of the steel ship construction use A131 AH32 structural steel. Due to the use environment requirements of EH500 steel plate and EH550 steel plate, it can meet the requirements of high strength, high toughness, high welding performance, and thickness direction performance.
