Description
Technical field
The present invention relates to a kind of welding material, belong to field of welding material, relate to a kind of argon arc welding solid welding wire for high-temperature steel plate particularly.
Background technology
The progress of the development of heat resisting steel and the energy, dynamic power machine has close relationship.In the new technology development fields such as thermal power generation, atomic energy, aerospace, aviation, oil and chemical industry, the quality of heat resisting steel performance is the key link of its success or not, and therefore, the importance of heat resisting steel improves day by day in recent years.Meanwhile, the exploitation for the supporting welding wire of heat resisting steel is also the emphasis advancing these industry developments.But there is creep rupture strength deficiency in the current welding wire for heat resisting steel welding, be applied in operating temperature below 580 DEG C the argon arc welding of boiler heating surface pipe and less than 540 DEG C jet chimneys and high-pressure bottle, petroleum refining unit and the welding effect of full argon welding poor.
For this reason, applicant carried out useful exploration and trial, have found result of the above problems, technical scheme described below produces under this background.
Summary of the invention
Technical problem to be solved by this invention: the problem that there is creep rupture strength deficiency for the existing welding wire for heat resisting steel welding, now provides a kind of argon arc welding solid welding wire for high-temperature steel plate guaranteeing weld seam creep rupture strength excellence.
Technical problem solved by the invention can realize by the following technical solutions:
For an argon arc welding solid welding wire for high-temperature steel plate, it is characterized in that, described argon arc welding solid welding wire contains the composition of following mass percentage:

In a preferred embodiment of the invention, described argon arc welding solid welding wire adds titanium rare earth alloy in steelmaking process, and the addition of this titanium rare earth alloy is 0.20 ~ 1.20%.
In a preferred embodiment of the invention, Ti:0.03 ~ 0.10% in the chemical composition of deposited metal.
In argon arc welding solid welding wire of the present invention, Design of Chemical Composition principle is as follows:
Composition C
C element is absolutely necessary element in low-alloy steel, effectively can improve weld strength.But too high C content may worsen weldability, increase cold cracking inclination, reduce the toughness of deposited metal, therefore the C content in the present invention is controlled to be 0.05 ~ 0.12%.
Composition Mn
Adding Mn element is that deposited metal provides certain intensity guarantee, be conducive to refinement seam organization, simultaneously, also deoxidation and desulfurization is conducive in the process of reaction, but composition Mn more than 1.5% after, the friable tissues such as bainite and martensite may be formed in weld seam, therefore the Mn content in the present invention be controlled to be 0.75 ~ 1.05%.
Composition Si
Si element add the mobility can improving molten bath, also the effect of deoxidation can be played, but simultaneously, once Si too high levels, also there will be the adverse influence such as slag inclusion or solidification cracking, also may cause serious splashing, affect processing performance, therefore the Si content in the present invention be controlled to be 0.45 ~ 0.70%.
Composition Cr
Oxidation resistant effect is mainly played in adding of Cr element, under oxidizing atmosphere and lower temperature, can form one deck tack very strong, fine and close sull.It is 1.10 ~ 1.40% that Cr content in the present invention controls.
Composition Mo
The content of Mo element, about 0.50% time, can reduce or suppress the temper brittleness that other elements cause, and the heat that can improve steel by force and creep strength.Therefore the Mo content in the present invention controls to be 0.45 ~ 0.65%.
Composition V
V element add the heat resistance that also can improve heat resisting steel by forming the carbide of small and dispersed.It is 0.20 ~ 0.35% that V content in the present invention controls.
Composition Ti
The a small amount of of Ti element adds the effect can playing deoxidation on the one hand, makes seam organization purer, on the other hand, by forming the precipitation of TiC, also can produce dispersion-strengthened action.Thus in the present invention, control Ti content Ti≤0.50%.
Composition P, S, Cu should control at zone of reasonableness as impurity element, thus in the present invention, control its content S≤0.025%, P≤0.025%, Cu≤0.30%.
Owing to have employed technical scheme as above, beneficial effect of the present invention is:
(1) rational composition range is selected, and in smelting, add titanium rare earth alloy, make the welding point combination property of this welding wire gained good, welding point tensile strength >=540MPa, yield strength >=440MPa, percentage elongation >=17%, normal temperature impact absorbing energy >=47J, 100,000 hours creep rupture strength >=60MPa of 580 DEG C.
