Description
Technical field
The present invention relates to welding wire technology field, particularly relate to a kind of low-temperature storage tank weldering with excellent toughness and drawing property
Silk.
Background technology
Along with developing rapidly of gas industry, transportable pressure vessel i.e. truck tank, railway tank and tank container
Manufacture increasingly paid close attention to by people, these hazardous materials transportation and equipment industry emerge rapidly.Low temperature movable type pressure holds
The inner canister temperature of device is the lowest, and outer tank is under room temperature, and for whole container, its thermograde is big, process bad easily
Producing the biggest thermal stress in weld seam lap-joint, commissure drawing property is poor, and corrosion-resistant and toughness does not reaches demand, easily produces and splits
Stricture of vagina and seepage, at present in the low-temperature storage tank of particular/special requirement, drawing, corrosion-resistant and toughness wlding performance are in urgent need to be improved.
Summary of the invention
The technical problem existed based on background technology, the present invention proposes a kind of has the low of excellent toughness and drawing property
Temperature storage tank welding wire, drawing property is good, corrosion-resistant and tenacity excellent.
A kind of low-temperature storage tank welding wire with excellent toughness and drawing property that the present invention proposes, its component percentage by weight
Ratio includes:
Surplus be Fe and other be inevitably mingled with.
Preferably, the content of C, Mn and Si meets functional relation: YMn=1.64 × ZSi+0.56×XC+0.011599；
XC、YMn、ZSiRepresent C, Mn, Si shared percentage by weight in component respectively.
Preferably, Ni Yu Cr weight ratio is 13-14.5:22-23.58.
Preferably, the weight ratio of Mn, Si and C is 1.6-1.7:0.22-0.26:0.009-0.01.
Preferably, the weight ratio of Co Yu B is 0.05-0.07:0.008-0.01.
Preferably, Ni Yu Mn weight ratio is 12-12.5:1.4-1.6.
Preferably, the described low-temperature storage tank welding wire with excellent toughness and drawing property, its component is by weight percentage
Including:
Surplus be Fe and other be inevitably mingled with.
The present invention has preparation method and the prior art preparation side of the low-temperature storage tank welding wire of excellent toughness and drawing property
Method is identical.
In the present invention, C, Si, Mn, P, S, Ni, Cr element mating reaction, can effectively promote to produce in a large number in weld metal
The fine acicular ferritic structure of high density dislocation, low-temperature flexibility is good, and wherein C, Mn, Si mating reaction can be effectively improved weld metal
Quenching degree, suppression pro-eutectoid ferrite generation, promote acicular ferrite formation, further with Ni, Cr, Cu mating reaction
Goods drawing property can be effectively improved, can meet that weld seam lap-joint is corrosion-resistant, the solder technology requirement of high intensity, high tenacity.
Wherein, chromium essentially consists in raising goods decay resistance, and the underlying cause is to add chromium in steel as alloy unit
After element, promote its internally paradoxical movement to be conducive to opposing corrosion failure aspect development.Concrete principle: chromium makes iron-based solid
The electrode potential of solution improves；Chromium absorbs the electronics of ferrum makes ferrum be passivated.Passivation is to cause metal owing to anode reaction is prevented from
The phenomenon being enhanced with alloy corrosion resistance.Constitute the theoretical a lot of of Metal and Alloy passivation, mainly have thin film opinion, adsorption theory
And electronic configuration opinion.I.e. chromium can form one layer of chromium oxide protecting film at stainless steel surfaces after oxidation, can effectively hinder
The entrance of the most extraneous soda acid factor and continuation corrosion.
The effect of nickel is just brought into play after coordinating with chromium, and nickel is the element forming austenite in steel, and nickel is same with chromium
Time when being present in rustless steel, nickel coordinates with chromium makes tissue change, so that the decay resistance of goods and processing performance
Improve, improve stainless mechanical performance, increase stainless ductility, create good condition for its deep-draw and shaping.
Carbon in rustless steel on tissue impact be mainly manifested in two aspects, on the one hand carbon is the element of stable austenite,
And the degree acted on is very big, on the other hand very big due to the affinity of carbon and chromium, with the carbide that chromium forms series of complex.
Affect stainless decay resistance.When additionally carbon amounts is higher, welding seam toughness declines, and weld seam medium pearlite ratio increases, and controls
The intercrystalline corrosion of chromium nickel stainless steel be can largely overcome at certain content, and welding and cold deformation are prone to.
The effect of manganese is that it reduces the critical quenching rate of steel, increases the stability of austenite, suppression Austria when cooling
The decomposition of family name's body, makes the austenite formed under high temperature be maintained room temperature, is the effective element of weld seam Strengthening and Toughening, in weld seam
Be conducive to deoxidation, prevent from causing the formation of the iron sulfide of fire check.
Silicon plays deoxidation and strengthening weld seam effect when welding, and it also forms ferritic element, at general rustless steel
In for often depositing impurity element, and stainless processing performance is also had a major impact by a certain amount of silicon, good to ensure when welding
Good mobility and molding.
