After a certain period of time, the steel products will reduce the toughness and increase the hardness, which is called aging effect. Generally, this effect is strongest at 200-300 ℃. The aging tendency of P460Nh-material-for-boiler-steel-plate.html target=_blank class=infotextkey>P460NH equivalent astm material, low carbon steel (about 0.1% carbon content) is especially large, while high carbon steel and alloy steel containing molybdenum, barium or tungsten are not easy to produce aging. For boiler steel plate, it is required that the reduction rate of impact initial property is not more than 50%, or the absolute value of impact initial property is not less than 3-3.5KGM / cm2.
Hot rolling processes more weight than any other manufacturing process available. Finished products are usually of a very high quality but can be left covered in mill scale due to the high-temperatures during processing. This oxide is removed via pickling to leave behind a smooth surface. This method is usually employed to produce sheet metal or other materials, including: Automotive parts (frames, wheels, water heaters etc.) Agricultural equipment Compressor shells Metal buildings Guard rails
