TB/T % 7b{0}}CUPVRE dur plât yw atmosfferig cyrydiad-gwrthsefyll dur ar gyfer rheilffordd. Ffosfforws a copr yn elfennau pwysig i gwella y atmosfferig cyrydu ymwrthedd o TB/T 1979 08CUPVRE dur plât.
Rare earths (RE) have many functions such as improving the fatigue strength of sodium and refining product grains. An important role of TB/T 1979 08CUPVRE steel plate is to add RE to make phosphorus evenly distributed in the middle of the steel, so that the atmospheric corrosion resistance of phosphorus can be fully exerted.
