EN10028-6 P690Q steel

With the development of science, technology and industry, higher requirements have been put forward for materials, such as higher strength, resistance to high temperature, high pressure, low temperature, corrosion resistance, wear and other special physical and chemical properties. In the field of pressure or cylinder,the P690Q gradually widely used by people.

P690Q iron is in the standard EN10028-6,which is weldable fine grain steels,quenched and tempered steel for pressure purposed steel.

Do you always confused by the P...Q,P...QL1,P...QL2?Please kindly note:
a)the basic series (P...Q)
b)series with elevated temperature properties(P...QH)
c) series with low temperature properties down to -40 °C (P...QL1);
d) series with low temperature properties down to -60 °C (P...QL2).
Please pick suitable P690Q according to your working environment.

Here attached the P690Q steel plates chemical composition and mechanical strength.

EN10028-6 P690Q Chemical Composition   

Grade	Chemical Composition
P690Q	The Element Max (%)
	C	Si	Mn	P	S	N	B
	0.20	0.80	1.70	0.025	0.015	0.015	0.005
	Mo	Cu	Nb	Ni	Ti	V	Zr
	0.70	0.30	0.06	2.50	0.05	0.12	0.15

The P690Q steel products percentage of grain refining elements shall be at least 0.015%, Alumnium is also included in these elements.
The minimum content of 0.015% applies here to dissolved aluminium.This value is regarded as attained if the total aluminium content is at least 0.018%

EN10028-6 P690Q Mechanical Property

Grade	Mechanical Property
P690Q	Thickness	Yield	Tensile	Elongation
	mm	Min Mpa	Mpa	Min  %
	t≤50	690	770-940	14%
	50＜t≤100	670	770-940	14%
	100＜t≤150	630	720-900	14%

From the above chart,the P690Q steel plates ,when T≤50,Yield strength(Mpa) is 690Mpa,  Tensile strength(Mpa) is 770-9400 Elongation(%)Min:14%.
