Is it reasonable for S235J0 and SA283 Grade C plate quenching to get martensite

Q460 steel plate has very high strength and is widely used in large ships, bridges, power station equipment, medium and high-pressure boilers, high-pressure vessels, rolling stock, hoisting machinery, mining machinery and other large welded structural parts. The price of S235J0 and SA283 Grade C plate, Q460 steel plate is related to the specifications. Generally speaking, the thicker the thickness, the higher the price. And S235J0 and SA283 Grade C plate, Q460 steel plate price is also related to the market situation. When the market demand is in the peak season, the steel supply exceeds the demand, the price will rise. Otherwise, the price may be lowered. Finally, it is related to the order quantity. The larger the quantity, the more advantageous the price.

In order to prevent the deformation of S235J0 and SA283 Grade C plate, wear-resistant composite plate during preheating, the steel plate with good quality should be selected first. The steel plate with serious carbide segregation should be reasonably cast and heat treated by quenching and tempering. For the large and non cast wear-resistant composite plate, the solution double refining heat treatment can be carried out. At the same time, the heating temperature should be reasonably selected and the heating speed should be controlled.

We have a large number of S235J0 and SA283 Grade C plate steel materials in stock, and provide deep processing services such as welding. In addition to simple welding parts, we can also weld H-beam, box column and other profiles. For such welded structure, our advantage is that there are high-quality and low-cost raw material steel plates, which can be cut into the S235J0 and SA283 Grade C plate required size and welded into steel products with required shape and size, without being limited by the specifications of rolling production lines.

Our company has established and constantly improved the customer service system and emergency response system. Through the customer service management system, we track the service of the after-sales service team and provide efficient and standard services in time. At the same time, the company formulates a regular return visit system, compares the historical cases of customer problems, proposes a pre solution, and ensures that the service is in place in a short time.
