Our company has sales department, technology department, quality inspection department, after-sales department, logistics department. Each department has professional knowledge and high professional quality, put customers first, think about the interests of customers, actively communicate with customers and solve problems smoothly.
After heat treatment and cold drawing hardening, 65Mn steel has higher strength, certain toughness and plasticity; under the same surface state and complete hardening, the fatigue limit is equivalent to that of alloy springs. However, due to poor hardenability, it is mainly used for springs of A588 grade B structural steel plate smaller sizes, such as pressure regulating springs, force measuring springs, round and square spiral springs on general machinery or drawn into steel wires as springs on small machinery.
The cold bending method is mainly used to produce cold-formed section steel and welded pipe. The cold bending method is to bend the steel strip or steel plate into various cross-section shapes by the cold bending machine in the cold state. If the A588 grade B structural steel plate steel pipe is bent into a circular, square or other hollow shape and welded by a proper welding method, it is a welded pipe. The advantages of cold bending: first, the cold-formed section steel is light in weight and large in bearing capacity, and it can save metal by replacing the hot-rolled section steel; second, it can produce all kinds of A588 grade B structural steel plate extremely thin, extremely wide and complex section steel which can not be produced by hot rolling.
S355NL steel plate is under EN10111 standard. We can regard A588 grade B structural steel plate, S355NL steel plate as Fine-grain structural steels, normalised rolled. S355NL steel plate is one mainly of Fine-grain structural steels, normalised rolled, The normalized rolled fine-grain structural steel S355NL is characterized by a minimum yield strength of 355 MPa, by good weldability and high resistance to brittle fracture, which is same with DIN:TStE355 and BS:55EE
Iron and steel goods, including pig iron, ingots, all kinds of steel and so on. Therefore, logistics companies are required to load evenly and evenly in the process of transportation, prevent moisture and prevent corrosion. It is necessary to prevent the A588 grade B structural steel plate steel sheet from being mixed with water when transporting the steel; it is necessary to prevent the A588 grade B structural steel plate steel from being mixed with water when transporting the steel; it is necessary to prevent the steel from being mixed with water when transporting the steel; it is necessary to prevent the steel from being mixed with water when transporting the steel; it is necessary to prevent the steel from being mixed with water when loading the A588 grade B structural steel plate steel sheet on the truck Good luck.
If you have steel demands in the near future, please send us inquiry in advance, as we have regular steel production plan and can arrange you a reasonable prodction time. Other than fresh production, we also have huge A588 grade B structural steel plate stocks for the most widely used steel materials. So that the customers need not wait too long to get their required steel. Welcome to contact us and consult steel price, our sales person will give you professional answers and suggestions.
