TB/T 1979 05CuPCrNi atmospheric corrosion resistant steel plate steel plate

The weathering resistance mechanism of TB/T 1979 05CuPCrNi atmospheric corrosion resistant steel plate is different from that of the general corrosion resistant alloy steel. The Cu element in 05CuPCrNi steel has the effect of electrochemical depolarization, which causes the steel base surface to form a tight and firm protective film for a certain time, so as to slow down the erosion of atmospheric factors.
