TB/T 1979 09CuPCrNi-A Weather Resistant Steel Plate

Also now more and more foreign customers learn about these china weathering steel grades and choosing them to replace the other weathering steel grades such as Cor-ten A, Cor-ten B, A588 Grade A, S355J2W, S355J2WP and so on.

TB/T 1979 09CuPCrNi-A has added phosphorous which makes the material best suited for gas flue applications and for aesthetic facility.

TB/T 1979 09CuPCrNi-A Chemical composition:

Grade	The Element Max (%)
09CuPCrNi-A	C	Si	Mn	P	S
	≤ 0.12	0.25-0.75	0.20-0.50	0.06-0.12	≤ 0.020
	Cr	Cu	Ni	RE
	0.30-1.25	0.25-0.50	0.12-0.65

Carbon Equivalent: Ceq = 【C+Mn/6+(Cr+Mo+V)/5+(Ni+Cu)/15】%

TB/T 1979 09CuPCrNi-A Mechanical Properties:

Grade	Thickness	Yield	Tensile	Elongation	Delivery state
09CuPCrNi-A	mm	Min Mpa	Mpa	Min %
	4<	345	480	24	Hot rolling
	≤ 4	310	440	26	Cold rolling

Generally the heat treatment for weathering steel plate 09CuPCrNi-A,09CuPCrNi-B,09CuP shall be under Hot rolling or hot rolled and annealing or cold rolling, Annealing have to be down when steel plate under cold rolled delivery condition. Also if it is agreed by both sides, the mill can do acid-washing after hot rolled for these weathering steel plates.
