Q415NH quench metal plate steel major added metal elements are nickel, copper. These elements change the basic properties of the original carbon steel. Let carbon steel has a better mechanical properties. Q415NH quench metal plate steel for better corrosion resistance and can be used as processing materials aboard, the container, the train tracks.Compared to stainless steel, only trace amounts of alloying elements, alloys such as weathering resisting steel elements of total phosphorus, copper, chromium, nickel, molybdenum, niobium, vanadium, titanium, etc. is only a few percent.

Q415NH chemical elements composition:

Q415NH
C	Si	Mn	P	S	Cu	Ni	Cr
0.12	0.65	1.10	0.025	0.030	0.20-0.55	0.12-0.65	0.30-1.25

Q415NH Mechnical property:

Thickness (mm)
Q415NH	≤ 16	> 16 ≤ 40	> 40 ≤ 60	>60
Yield strength (≥Mpa)	415	405	395	395
Tensile strength (Mpa)	520-680

Q415NH Use:
Q415NH quench metal plate steel has a protective layer of rust resistance to atmospheric corrosion, it can be used in the manufacture of vehicles, bridges, towers, containers and other steel low-alloy structural steel.
