The company adheres to the LR grade D seafaring ship steel 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 LR grade D seafaring ship steel and seek common development!
Steel plate is divided into rolling, hot rolling and cold rolling. The width of the thin plate is 500 ~ 1500 mm; the width of the thick plate is 600 ~ 3000 mm. Thin plates are classified according to steel types, including ordinary steel, steel, alloy steel, spring steel, stainless steel, tool steel, heat-resistant steel, LR grade D seafaring ship steel, bearing steel, etc .; according to use, there are ship plates, pressure vessel plates, atmospheric corrosion-resistant steel plates, bulletproof steel plate.
Wear resistant steel is very wear-resistant: for example, excavator bucket, long-term excavation requires good wear resistance. Wear resistant steel has a very high hardness: for example, scraper conveyor, if the hardness is not up to standard, it is extremely easy to fracture, resulting in very serious consequences. Wear resistant steel has good corrosion resistance: many equipment need to transport chemical corrosion products, so corrosion-resistant mechanical equipment is needed. LR grade D seafaring ship steel, Wear resistant steel has good fatigue resistance: such as bearing steel ball, which can do fast and repeated movement, and need to guarantee performance.
The research methods of isothermal treatment of LR grade D seafaring ship steel, wear-resistant plate include many excellent technologies, such as optical microscope, transmission electron microscope, X-ray diffractometer and electron backscatter diffraction technology. With the increase of annealing temperature, the proportion of ferrite in wear-resistant plate will gradually decrease, and bainite will increase, while the retained austenite will be distributed in ferrite grain boundary and crystal in elliptical and fine strip shape.
