The strength and shortcomings of S460QL steel tubing weight

Since the beginning of this year, the global S460QL steel tubing weight steel pipe industry, like many other industries, is facing severe market situation. The difference is that novel coronavirus pneumonia is not only affected by the epidemic, but also closely linked to the oil and gas industry, and the global S460QL steel tubing weight steel tube industry will also suffer from the "flash collapse" of international oil prices in March.

Our company's business departments are a group of excellent and hard-working employees, who constantly carry out knowledge updating and steel knowledge training every day, only to provide better and professional services to customers.

Main characteristics of 12Cr1MoV Steel: compared with 12CrMoV steel, 12Cr1MoV steel has higher oxidation resistance and thermal strength. The creep limit of 12Cr1MoV steel is very close to the endurance strength value, and it has high plasticity under the condition of endurance tension; the processability and weldability of 12Cr1MoV steel are good, but it needs to be preheated to 300 ℃ before welding, and stress removal treatment after welding. 12Cr1MoV steel is widely used in Superheater, header and main steam pipe of high pressure, ultra-high pressure and subcritical utility boiler.

The main competitive means adopted by major domestic ports are to expand ports, build deep-water berths and channels, improve service quality to reduce the comprehensive cost of customers, and at the same time, to improve competitive advantage, we should also take appropriate measures to reduce relevant costs and prices.

S460QL steel tubing weight, Q345B low alloy steel plate composition:
1) Low carbon: Due to the high requirements for toughness, weldability and cold forming properties, its carbon content does not exceed 0.20%;
2) Add manganese-based alloying elements;
3) Adding auxiliary elements such as niobium, titanium or vanadium: a small amount of niobium, titanium or vanadium forms fine carbides or carbonitrides in the Q345B steel, which is conducive to obtaining fine ferrite grains and improving the strength and toughness of the steel;
In addition, adding a small amount of copper (≤0.4%) and phosphorus (about 0.1%) can improve the corrosion resistance. Adding a small amount of rare earth elements can desulfurize and degas, purify steel, improve toughness and process performance.

The company will rely on its good reputation, excellent hot-rolled plates, steel pipes, steel structure products, and intimate S460QL steel tubing weight after-sales service to customers. I would like to express my heartfelt thanks to the old and new friends and customers who have always given care, support and help to the company!
