Abstract
The invention discloses a chrome molybdenum steel plate which is mainly used for manufacturing a boiler valve and a container, wherein the chrome molybdenum steel plate consists of the following chemical components in percentage by weight: 0.08-0.12% of C, 1.2-1.5% of Cr, 0.5-0.8% of Mo, 0.05-0.08% of V, 0.03-0.05% of Ti, 0.01-0.05% of N, 0.01-0.03% of Ni, less than 0.2% of P+S+Si+Mn, and the balance of Fe and inevitable impurities, wherein P+S is less than 0.03%. The chrome molybdenum steel plate disclosed by the invention is resistant to high temperature, is strong in hydrogen corrosion resistance, has relatively high high-temperature lasting strength and creep limit, and has strength and rust resistance which are superior to those of chrome molybdenum steel on the market.
Description
Technical field
The present invention relates to a kind of steel plate, particularly a kind of chrome molybdenum steel plate.
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.
Chromemolybdenum steel has good shock resistance and weldability, is applicable to the valve and the container that make boiler, and meanwhile, its shortcoming is that hardness is inadequate, easily gets rusty.
Summary of the invention
The object of the invention is to overcome the defect existed in prior art, a kind of chrome molybdenum steel plate, is mainly used in the manufacture of boiler valve and container, it is characterized in that, its chemical composition is by weight percentage: C:0.05-0.1, Cr:1.2-1.5, Mo:0.5-0.8, V:0.05-0.08, Ti:0.03-0.05, N:0.01-0.05, Ni:0.3-0.5, P+S+Si+Mn < 0.2, wherein, P+S < 0.03, surplus is Fe and inevitable impurity.
Wherein, the effect of each composition is as follows:
C: carbon is the one of the chief elements of Industrial Steels, the Properties and Microstructure of steel is decided by the content of carbon in steel and the form of distribution thereof to a great extent.The effect of carbon is the element of stable austenite on the one hand, is the carbide forming series of complex with chromium on the other hand.The content of carbon is controlled at 0.05-0.1%, on the basis of proof strength, erosion resistance and the weldability of steel plate can be improved;
Cr: the hot strength that can improve steel, can improve its creeping limit and the creep rupture strength limit significantly, and chromium is as alloying element, can improves the corrosion resistance of steel, make iron passivation, alleviates getting rusty of steel;
Mo: molybdenum has the effect of solution strengthening to ferrite, can improve the stability of carbide, and then improves the hot strength of steel;
V: vanadium and carbon and nitrogen have extremely strong bonding force, can form carbide and the nitride of stabilizer pole in steel, keeps fine grain structure when comparatively high temps, improve thermostability and the intensity of steel, but content of vanadium is too high, can play retroaction, in the present invention, content controls at 0.05-0.08%;
Ti: the effect of titanium in steel be crystal grain thinning and strengthening steel mainly, and Be very effective;
N: nitrogen can improve the intensity of steel, low-temperature flexibility and weldability, increase aging sensitivity, when adding Al, Ti or V in molten steel, nitrogen can be fixed in AlN, TiN or VN, can eliminate timeliness tendency;
Ni: nickel is excellent corrosion resistant material is also the important alloy element of steel alloy, when nickel and chromium are present in stainless steel simultaneously, the tissue of chromium steel can be made to change, thus the corrosion resistance nature of steel and processing performance are improved.
Of the present inventionly a little to be with beneficial effect: the characteristic improving chrome molybdenum steel plate insufficient strength and easily get rusty.
Embodiment
