How much is the marine steel per ton?According to the difference of quality grade and strength grade, as well as the difference of plate size, production area, and user requirement, the price of P235GH steel material plate fluctuates greatly. At present, the market price of marine plate is about 3800 yuan per ton to 5800 yuan per ton. Generally, the most commonly used marine plate price is about 4000 yuan per ton.

High-temperature boiler steel plates such as 15CrMoR plate, 12Cr1MoVR steel plate, ASME SA387 grade 22 steel, A387 Gr 91 boiler steel, ASME SA1017 Gr 23, SA1017 Gr 911, SA1017 Gr 122 steel, p235gh steel material, must have features of:Sufficient high temperature durability and durable plasticity;Good high temperature tissue stability;Good high temperature oxidation resistance (heat resistance);Good hot and cold processing technology (mainly refers to cold bending deformation and weldability), etc.

As the thickness and hardness of p235gh steel material increase, the tendency to crack at the cutting edge increases. In order to prevent the p235gh steel material from cutting cracks, preheating should be carried out before p235gh steel material cutting. Special attention should be paid to preheating to make the entire p235gh steel material interface evenly heated to avoid local overheating in the area contacting the heat source. If the whole p235gh steel material cannot be preheated, the partial preheating method can be used instead.

Since its establishment, the company has participated in several key railway and highway projects. After years of development, the company’s p235gh steel material domestic market has been exported to more than a dozen provinces and cities including Kunming, Shenzhen, Hunan, Sichuan, Shanghai, Nanjing, Heihe, Jilin, Inner Mongolia, and Xinjiang . International trade is exported to Kazakhstan, South Korea, Vietnam, South Africa and many other countries, and has been well received by customers.
