Chinese manufacturer p235gh equivalent material price

The Indian customer purchased our A516 Gr 70 pressure vessel steel plates to make tanks. They have very strict requirement for raw materials quality. For the A516 Gr 70 pressure vessel steel plates, they asked for Normalizing, 0℃ impact, A578 UT test, PWHT and so on tests, our Q/C department witness the production process with the technician from the customer company together. Meanwhile, we arrange BV inspection to check the quantity, spray mark, stamp on the A516 Gr 70 pressure vessel steel plates, and so on.

The sulfur element (S element) comes from the ore and fuel coke of steelmaking. It is a harmful element in P235GH equivalent material etc. steel. Sulfur exists in steel in the form of iron sulfide (FeS). FeS and Fe form a low melting point (985℃) compound. The hot working temperature of steel is generally above 1150 - 1200℃, so when the steel is hot working, the premature melting of FeS compound causes the workpiece to crack, which is called "hot brittleness". It reduces ductility and toughness of steel and causes cracks during forging and rolling. Sulfur is also detrimental to welding performance and reduces corrosion resistance.

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

From the order to the delivery, there are three quality inspections to ensure that the qualified rate of finished products is more than 100%. We promise that every order will be tracked in a timely manner to ensure that customers can receive goods safely and constantly listen to their opinions and suggestions, reflect on our own problems, and let customers feel at ease. We have a large warehouse in Shanghai and Tianjin, which can provide customers with sufficient sources of supply.
