Description
Technical field
The present invention relates to alloyed hot-dip galvanized steel plate, there is excellent stampability, the hot-dip galvanized steel sheet of erosion resistance, as automobile body outside plate.
Background technology
Because need through dark pressure processing to improve the feature designed by it for the alloyed hot-dip galvanized steel plate (being sometimes called below " GA ") of car body outside plate, thus require that they have higher toughness (unit elongation E1) and higher plasticity (Lankford value, r value).High tenacity and this problem of high-ductility to be obtained for solving simultaneously, from steel plate materials performance perspective, having developed the method for C, N, P, S equal size contained in a series of minimizing steel.Also best hot rolling and cold-rolling process is developed.
Combine to the requirement of steel plate, that this coating must not exist to the feature request of GA steel plate coating layer: 1) " flour particle " makes the structure efflorescence containing flour particle and stripping because flour particle does not produce distortion with steel plate in the course of processing, with 2) " thin slice ", when aligning with pressing mold, peel off with flakey containing lamellated structure.If there is this phenomenon, the plating particle of stripping retains in pressing mold, therefore, can cause a large amount of undesirable load moulds at surface of steel plate.Further, the solidity to corrosion of coating self is also lost.
Summary of the invention
The object of the invention is to obtain alloyed hot-dip galvanized steel plate, this steel plate has satisfied punching performance and erosion resistance simultaneously, realizes this object by using the steel plate reducing C, N, P, S content in steel plate.According to the present invention, provide and there is superior punching performance and the alloyed hot-dip galvanized steel sheet of erosion resistance, the alloyed hot-dip zinc-coated coating that matrix surface of steel plate is formed is containing the Fe of 9.5-11.5%, the Al of 0.35-0.45%, the Pb of 0.01-0.05%, surplus is Zn, and the thickness of coating is 40-60g/m2; This alloyed hot-dip zinc-coated layer surface also has a kind of Fe-Zn-Ni alloying coating layer; The moiety of matrix steel plate is: the C of 0.0005-0.0015%, the Si of 0.01-0.02%, the Mn of 0.08-0.10%, the S of the P of the Al of 0.3-0.45%, 0.005-0.008%, 0.002-0.005%, the O of 0.002-0.004%, the N of 0.002-0.003%, above per-cent is all weight percentage, and the punching press value R of described steel plate galvanized is more than 2.
As preferably, matrix steel plate at least also containing one or both in the Nb of Ti or 0.001-0.03% of 0.002-0.02%, wherein C/3≤(Ti+Nb)/40-(5/3N+3/2S+11/9P)/22≤2C.
As further preferred, the B of matrix steel plate also containing 0.0001-0.001%.
A brief description is done to composition each in steel below:
First, the composition being used as coating material contained in steel plate is determined as follows, to obtain satisfied desired properties and very economical product.
C:C is the element directly determining hardness of steel.For obtaining the very high processibility (high E1, r value) of the object of the invention, its content is more few better.Therefore its content should be 0.0005-0.0015%, preferred 0.0008-0.0012%, and more preferably 0.001%.
N, P and S: N, P and S in the tissue of steel reduce E1 and r value.Identical with the situation of C, their content is more few better.Determine that N, P and S must be respectively 0.002-0.003%, 0.005-0.008%, 0.002-0.005%, respectively preferably 0.0025%, 0.006-0.007%, 0.004-0.06%.
O: if containing excessive O in steel, it precipitates in the form of an oxide, thus, reduces E1 and r value.Therefore, its content is 0.002-0.004%, preferably 0.003%.
Mn: if add Mn in steel, it is combined with S then to precipitate and become affects without for what.Therefore, when adding a small amount of Mn, there is not obvious impact from the viewpoint of material.But, if its content exceed about 0.1%, E1 and r value can reduce gradually.Therefore, the content of Mn is necessary for 0.08-0.10%, and preferably 0.009%.
Si: identical with Mn, reduces E1 and r value containing a large amount of Si in steel and damages the weldability of coating.Therefore, Si content 0.01-0.02%, preferably 0.015%.
Ti and Nb:Ti and Nb and C combines and precipitates with the form of TiC and NbC, therefore improves processibility.Therefore, Ti and Nb need be greater than 1 to the atomic ratio of C.Its content is respectively the Ti of 0.002-0.02%, the Nb of 0.001-0.03%.But can increase cost because adding too much this element, then atomic formula is maximum is about 6.Another because the associativity of Ti and N or S is stronger than the associativity with C, the equivalent of N and S, P should be deducted when therefore must determine the content of Ti.Especially, the amount of Ti, Nb should meet following formula: C/3≤(Ti+Nb)/40-(5/3N+3/2S+11/9P)/22≤2C.
Al: when adding Ti, Nb, for the object preventing oxidational losses, Al is necessary to add more than 0.3%, and eliminate it after N, S chemical combination in Al and steel and affect.In addition, if addition is higher than 0.45%, then saturated and uneconomical, elect 0.35-0.4% as.
Further, in steel plate of the present invention, apart from outside above-mentioned essentially consist, if the B adding more than 0.0001% can be better.Because B is to strengthening crystal boundary, weldability and the cold working fragility of improving coating are all effective.If add-on is higher than 0.001%, then plasticity loss, thus the upper limit is 0.001%, elects 0.0003-0.0008% as.In addition, following for the composition restriction reason in coating.The alloyed hot-dip zinc-coated coating that matrix surface of steel plate is formed is containing the Fe of 9.5-11.5%, the Pb of the Al of 0.35-0.45%, 0.01-0.05%, and surplus is Zn, and the thickness of coating is 40-60g/m2; This alloyed hot-dip zinc-coated layer surface also has a kind of Fe-Zn-Ni alloying coating layer;
Alloyed hot-dip galvanized steel plate is impregnated into by steel plate after in galvanizing bath, steel plate is heated, Fe so in raw steel plate is diffused in coating and forms zn-fe alloy layer, improve all significantly than the solidity to corrosion of former simple steel plate galvanized, chemical treatment properties, coating weldability like this, these performances are by adjusting to about more than 9.5% and preferably obtaining by the Fe content in coating layer.In addition, Fe content must arrive about more than 9% to prevent the growth of phase layer.On the other hand, if Fe content exceedes about 11.5%, when even being controlled below in described scope by Al content in coating, then hard, frangible г phase there will be, and is therefore harmful to pressure processing.Therefore, the Fe content in coating is necessary for about 9.5-11.5%.
In coating, contained Al amount affects the phase composite of the zn-fe alloy formed when alloying.If Al content is less than about 0.35%, then forms г phase, therefore can cause undesirable efflorescence.If Al content exceedes about 0.45%, sufficient alloying can not be realized.Therefore, in coating, Al content is about 0.35-0.45%.Because the solidity to corrosion of Pb to coating has detrimental action, therefore, Pb content in coating is controlled at 0.01-0.05%.By solidity to corrosion, the coating amount of plating is necessary for 40g/m2.But as coating is too thick, when carrying out press working, then coating with steel plate deformed, can not can cause efflorescence.Therefore, the coating maximum quantity be plated on steel plate is defined as about 60g/cm2.
