Description
Technical field
The present invention relates to a kind of heat-resisting boiler sheet.
Background technology
Boiler sheet is one of material very crucial in boiler manfacturing, is mainly used to manufacture the vitals such as shell, drum, header end cap, suspension and support in boiler.Boiler sheet works under being usually in medium and high temperature and high pressure conditions, except bearing comparatively high temps and pressure, is also impacted, and fatigue loading and the gentle corrosion of water, working conditions is poor.If destructive accident in use occurs boiler, serious loss will be caused.Therefore, improve the performance of boiler sheet, reduce manufacturing cost simultaneously and become a problem demanding prompt solution in recent years.
Summary of the invention
The present invention is directed to the problems of the prior art, provide a kind of heat resistance steel plate, described steel plate contains: C:0.05-0.16, Si:0.06-0.45, Mn:0.25-0.8, N:0.003-0.015, V:0.05-0.18, Mo:0.5-1.5, Cr:1.5-2.5, P:0.01-0.03, S:0.003-0.01, surplus is Fe and inevitable impurity.
More preferably, above-mentioned heat resistance steel plate also contains by weight percentage: Ti:0.03-0.06; B:0.001-0.005, Nb:0.05-0.15.
Advantage of the present invention and beneficial effect are: the cost 1) reducing heat-resisting steel sheet and plate; 2) according to the heat-resisting steel sheet and plate that said ratio is made, thickness can be made into 18-60mm, ultrasonic inspection rank≤II grade, yield strength R
pbe not less than 320Mpa, tensile strength is 520-600Mpa, and unit elongation is 21-25%, normal temperature ballistic work A
kV2be not less than 350J, functional; 3) low containing P, S amount, safety and environmental protection.
Embodiment
Below in conjunction with embodiment, the specific embodiment of the present invention is further described.Following examples only for technical scheme of the present invention is clearly described, and can not limit the scope of the invention with this.
The technical scheme that the present invention specifically implements is:
A kind of heat resistance steel plate, described steel plate contains: C:0.05-0.16, Si:0.06-0.45, Mn:0.25-0.8, N:0.003-0.015, V:0.05-0.18, Mo:0.5-1.5, Cr:1.5-2.5, P:0.01-0.03, S:0.003-0.01, surplus is Fe and inevitable impurity.
Above-mentioned heat resistance steel plate also contains by weight percentage: Ti:0.03-0.06; B:0.001-0.005, Nb:0.05-0.15.
Heat-resisting steel sheet and plate thickness obtained by above-described component can be made into 18-60mm, ultrasonic inspection rank≤II grade, yield strength R
pbe not less than 320Mpa, tensile strength is 520-600Mpa, and unit elongation is 21-25%, normal temperature ballistic work A
kV2be not less than 350J, functional.
The above is only the preferred embodiment of the present invention; it should be pointed out that for those skilled in the art, under the prerequisite not departing from the technology of the present invention principle; can also make some improvements and modifications, these improvements and modifications also should be considered as protection scope of the present invention.
