TB/T 1979 05CuPCrNi weather resistant steel plate

TB/T 1979 05CuPCrNi is a kind of atmospheric corrosion resistant steel, and it contains the Cu element, which can make the plate surface form a protective film, in the air exposure for a long time will form a brick red appearance, to prevent corrosion.

Please see the following table for the chemical properties and physical properties of 05CuPCrNi weather resistant steel plate:

C max	Si	Mn	P	S max	Cu	Ti	Cr	Ni	Re
0.090	025-0.50	0.20-0.50	0.060-0.12	0.020	0.25–0.50	-	0.30-1.25	0.12-0.65	-

Grade	Yield Strength (MPa) min.	Tensile Strength (MPa) min.	Elongation min. %
TB/T 1979 05CuPCrNi	310	440	26

In TB/T 1979 05CuPCrNi weather resistant steel plate, the content ratio of Ni and Cu is 1∶3 can form the alloy phase, so control the Ni content of cu 0.3% steel is greater than 0.1%, it can prevent cracking in the process of hot rolling.
