What is the difference between ordinary carbon steel and Q355NH railway steel

Standing at a new historical starting point, we adapt to the requirements of supply side Q355NH railway steel structural reform, adhere to the overall strategy of "innovation driven, quality leading, quality improving and efficiency increasing, transformation and development", and constantly improve the development concept and development level with a forward-looking vision and grand vision. Now we have been ranked the International leading Q355NH railway steel steel materials supplier.

In the market, the price of Q355NH railway steel, alloy coil plate is unstable. When purchasing alloy plate, first of all, you need to observe the market situation, and then do a price analysis. In this way, you can buy the most favorable alloy coil plate. At the same time, you can also go to the Internet to inquire about the manufacturer of alloy coil plate. It is necessary to consult the price and ask several manufacturers for comparison. For the Q355NH railway steel, alloy coil plate quality, you can visit the manufacturer to have a look at the material and quality. Finally, you can choose the most suitable manufacturer to put orders.

Just as Q355NH railway steel, 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.

Although Q355NH railway steel, low carbon steel has excellent plasticity, toughness and processing technology, its strength is low and its corrosion resistance is not strong enough. On the basis of ordinary low carbon steel, the low alloy structural steel with high strength, high toughness, good weldability and corrosion resistance can be obtained by adding a small amount of alloy elements and the total amount is less than 3%. Manganese is the main additive element in this kind of steel, and its content is about 1% ~ 1.6%.

S355NL steel plate is under EN10111 standard. We can regard Q355NH railway steel, 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
