Welcome to BBN High Strength Steels Factory
45MnB characteristics and applications: alloy structural steel has good hardenability, the critical hardenable diameter in oil reaches 17 ~ 31mm. The machinability of steel S460QL steel tubing weight is good, the forging and heat treatment process performance is also good, the tendency of grain growth, oxidation, decarburization and heat treatment deformation is also small when heated. 45MnB steel is mainly used for gears on machine tools, spindles of drilling machines, turning shafts and cams of tractors.
The company adheres to the S460QL steel tubing weight business tenet of "integrity casting strength, cooperation creating win-win", takes value-added service of supply chain as the tenet, and under the premise of existing market, bulk trade, logistics distribution and other advantages, develops a new comprehensive steel industry model combined with informatization. And will continue to provide customers with high-quality steel products and good service. We sincerely welcome new and old customers to join hands with our company S460QL steel tubing weight and seek common development!
The preparation of S460QL steel tubing weight galvanized steel before welding is the same as that of ordinary low-carbon steel. It is necessary to carefully handle the groove size and nearby galvanized layer. In order to achieve penetration, the groove size shall be appropriate, generally 60 ~ 65 °, with a certain gap, generally 1.5 ~ 2.5mm; in order to reduce the penetration of zinc into the weld, the galvanized layer in the groove can be removed before welding. In the practical work, the centralized beveling, no blunt edge technology for S460QL steel tubing weight centralized control, two-layer welding process, reducing the possibility of incomplete penetration.
As S460QL steel tubing weight, alloy 400 is a kind of metal with good corrosion resistance, it shows good uniform corrosion resistance in the marine atmosphere. This is because alloy 400 can form a very thin and tough protective film. Uniform corrosion is one of the easiest forms of corrosion to deal with, because engineers can quantitatively determine the corrosion rate of metals and accurately predict the service life of metals.
We have a professional after-sales department to collect all information related to customers, so as to make relevant treatment in time according to the information, and file it; guide the user's product use methods and precautions; coordinate with the sales department, visit customers regularly, understand the customer's use and new requirements, and make a customer visit record; When communicating with customers, they should be enthusiastic and careful to understand the situation of product problems and put forward solutions
