Best quality cheap mechanical property of BP440

The company has superior geographical location and convenient transportation. After more than 20 years of market trials and tribulations, from small to large, from weak to strong, in order to meet the needs of customer extension development, the company expanded the deep processing services of cutting steel pieces. Now we have built a business system integrating steel plate, steel plate cutting and steel deep processing. The company provides one-stop solution for customers with lower price, higher quality and faster response speed.

Mechanical property of BP440,Corrosion-resistant steel plate significantly improves the corrosion resistance of structural parts and prolongs the service life of structural parts. It can be used to make various structural parts that work in atmospheric environments and corrosive gases and liquids. Plate delivery status: According to performance and user needs, steel plates can be delivered in hot rolling, controlled rolling, normalizing, annealing, tempering, normalizing + tempering, quenching and tempering,mechanical property of BP440.

Mechanical property of BP440,Just as mechanical property of BP440, the boiler steel plate also has strict control of chemical composition for the material, especially harmful elements such as phosphorus and sulfur, and residual elements such as chromium, nickel, and copper; during smelting, good deoxidation and removal of non-metallic inclusions should be carried out to ensure good quality, plasticity and toughness The organizational structure requires uniformity, and the grain size is controlled within a certain range; there are also strict requirements for surface quality and internal defects In addition, the boiler steel plate mechanical properties at room temperature and high temperature must be guaranteed,mechanical property of BP440.

Welding is mainly used for manufacturing metal structure parts, and also for manufacturing machine parts. The welding connection performance is good, and it is convenient to weld steel plates, profiles or castings and forgings according to the needs. At the same time, welding can also connect different shapes and sizes (plate thickness, pipe diameter) or even different materials, so as to reduce weight, save materials, optimize resources and other purposes. The welding structure has high rigidity, good integrity, and easy to ensure air tightness and water tightness, so it is especially suitable for manufacturing hollow structures with high strength and large rigidity (such as pressure vessels, pipes, boilers, etc.).

Mechanical property of BP440,According to GB 11251 technical standard, the chemical composition of 40Cr structural steel plate is as follow: Carbon content is 0.37-0.44 %, Silicon content is 0.17-0.37%, Manganese content is 0.50-0.80%, Chrome content is 0.80-1.10%. 40Cr steel is usually in shape of 40Cr steel plates and bars. GB 11251 is for 40Cr structural steel plate with thickness range of 4-30mm. The tensile strength of 40Cr structural steel plate is 550-800Mpa. And its min. Elongation is 16%.

Mechanical property of BP440,We should help solve the customer's problems in time, not just verbally, without solving the problems or shirking the responsibility. Improving after-sales efficiency can make customers feel respect. We should take their problems seriously and show sincerity. It can also give customers a good impression and reduce the negative impact.
