Correct welding method for A572 Gr 42 carbon steel plate sheet

The business department is mainly responsible for communicating with customers, from the manufacturing of steel plates, steel pipes and other products, knowing customers' needs and processing conditions, etc. within the time agreed with customers, the delivery time is short, the price is the most competitive, and the service is the best. Their responsibilities are to deal with customer consultation, solve customer problems, update production plans, and instruct the logistics department to deliver products to customers.

According to the guarantee conditions of delivery, China and some countries divide the ordinary carbon steel into three categories: Class A steel, which only guarantees the mechanical properties, not the chemical compositions； Class B steel, which only guarantees the chemical compositions, not the mechanical properties; special steel (Class C steel), which not only guarantees the chemical compositions, but also the mechanical properties. Class C steel A572 Gr 42 carbon steel plate sheet is often used to manufacture important structural parts. Density of ordinary carbon steel: 7.85 g / cm3.

Grades A572 Gr 42 carbon steel plate sheet, Q345 (16Mn) and Q390 steel have good comprehensive mechanical properties, good welding performance, cold and hot workability and corrosion resistance. C, D, E grade steel has good low temperature toughness. Mainly used for ships, boilers, pressure vessels, petroleum storage tanks, bridges, power station equipment, lifting and transportation machinery and other higher-load welding structural parts.

How to distinguish between hot rolled and cold rolled process?The hot-rolled steel sheet has low strength, easy production and processing, and good plasticity. The process performance of the hot-rolled steel plate is poor (air oxidation and low smoothness), but the plastic deformation is good. Generally, it is medium and thick plate, A572 Gr 42 carbon steel plate sheet, high compressive strength, high strength, and high surface smoothness. Cold-rolled steel sheets have high strength and relatively difficult production and processing, but they are not easy to deform and have high compressive strength.

SG255 gas cylinder A572 Gr 42 carbon steel plate sheet steel is widely used in petroleum, chemical industry, power station, boiler, etc, used to make the reactor, heat exchanger, separator. The company is a professional gas cylinder steel exporter and a steel stockist in china.
