Pipeline steel A573 Grade 65 steel sections is mainly used for the transportation of oil and natural gas. Pipeline steel (LPS) is mainly used for processing and manufacturing oil and gas pipelines. Oil and gas pipeline network is the most convenient and safe channel connecting the resource area and market area. Its rapid construction will not only relieve the pressure of railway transportation, but also help to ensure the safe supply of oil and gas market and improve the level and capacity of energy security.

NM series wear-resistant steel plates have uniform hardness, avoid the local fracture phenomenon caused by uneven hardness. Compared with ordinary steel plate, NM360 steel plate has wear resistance of not less than twice, NM400 steel plate has wear resistance of not less than 2.5 times, and NM550 steel plate has wear resistance of not less than 4 times. The wear-resistant steel plate combines the characteristics of high strength, high hardness, weldability and easy bending.

Diffusion annealing of A573 Grade 65 steel sections, wear-resistant plate is to reduce the non-uniformity of chemical composition and structure of metal ingot, casting or forging billet, heating it to high temperature and holding for a long time to make the elements in the steel plate fully diffuse. Due to the long heating cycle and high temperature of diffusion annealing, although the composition of the steel is uniform, the structure of the steel plate is seriously overheated, and the grains grow violently, and the toughness and plasticity are poor. Diffusion annealing is widely used in ingots, casting and forging billets with high quality requirements due to its high energy consumption and serious burning loss.

Chemical composition of Q390C steel plate: C ≤ 0.20, Si ≤ 0.50, Mn ≤ 1.7, P ≤ 0.030, S ≤ 0.030, Nb ≤ 0.07, V ≤ 0.20, Ti ≤ 0.20, Cr ≤ 0.30, Ni ≤ 0.50, Cu ≤ 0.30, N ≤ 0.015, Mo ≤ 0.10, Al ≤ 0.015. The mechanical properties of Q390C steel plate are: yield strength ≥ 390 MPa, tensile strength 470-620 MPa, elongation after fracture ≥ 18%, impact energy 34J. A573 Grade 65 steel sections, Q390C steel plate is used for bridges, vehicles, ships, workshops and other large structural parts, high and medium pressure Petrochemical vessels, boiler tubes, pipes, superheaters, pressure vessels, heavy machinery, etc. application.
