High tensile strength weathering steel plate Q415NH which owned tensile strength within 520-680 Mpa.The yield strength shall be above 415Mpa for the thickness equal and bellows 16mm.
According to the different impacting temperature,Q415NH steel plates can be Q415NHA,Q415NHB,Q415NHC,
Q415NHD,Q415NHE.Q415NHE need to be done minus 40 centigrade low temperature impacting test and Q415NHA need no impacting test.
The specifications:
Thickness: 3mm--150mm
Width: 30mm--4000mm
Length: 1000mm--12000mm
