Definitions
- the invention relates to a coated steel sheet or strip, with a ground coating made of steel, onto at least one upper side of which a zinc coating is applied by hot-dip galvanizing.
- the zinc coating ensures a high degree of corrosion resistance.
- a conventionally alloyed zinc coating in a spray test according to DIN 50021 carried out on a bright, unpainted specimen, with a coating of 25 g/m 2 , red rust already occurs after 24 hours, while with a coating of 70 g/m red rust does not occur until after 120 hours.
- the thickness of the coating required with the prior art for adequate corrosion resistance does, however, incur problems with regard to weldability. This applies in particular if the intention is that through-welding is to be produced by means of laser welding in the overlap joint without any joint gaps at high welding speeds, such as is required in the motor vehicle chassis construction sector or the domestic engineering sector.
- the seam produced by such welding should be free of passage holes, should be largely free of cratering, and should not have any open pores.
- the invention in one embodiment, features a flat steel product which possesses an optimum combination of high corrosion resistance and optimum weldability and which is particularly well-suited for use as a material for motor vehicle chassis construction or for the production of domestic appliances.
- the invention features a coated steel sheet or strip, which has a ground coating made of steel, onto at least one upper side of which a coating is applied by hot-dip galvanizing, the coating being formed from a melt consisting of 0.05-0.30% by weight Al and 0.2-2.0% by weight Mg, the remainder being zinc and unavoidable impurities, and on each side, with a coating thickness of a maximum of 3.5 ⁇ m and a coating weight of a maximum of 25 g/m 2 , guarantees that the steel sheet, in the salt spray mist test carried out in accordance with DIN 50021-SS, shows the first formation of red rust at the earliest after 250 hours.
- a hot-dip galvanized flat steel product according to the invention possesses surprisingly good corrosion resistance with a coating weight minimised in relation to the prior art coating weight of a maximum of 25 g/m 2 on each side.
- the low coating weight and the low thickness of the coating associated with this, of a maximum of 3.5 ⁇ m on each side, in combination with the high corrosion resistance, makes sheet or strip according to the invention particularly well-suited for the production of components which are manufactured by the welding of individual sheet elements. Accordingly, with steel sheets produced in accordance with the invention, elements for motor vehicle chassis or domestic appliance technology can be manufactured in particular, in that the individual sheet components formed from sheet or strip according to the invention can be welded to one another by laser beam welding at high welding speeds economically and with optimum results.
- the corrosion resistance according to the invention is determined on the basis of a salt spray mist test in accordance with DIN 50021-SS in a corrosion short-term test process on bright unpainted steel sheet, in which a neutral 5% NaCl solution, as the corrosive agent, is sprayed continuously at a temperature of 35 ⁇ 2° C. in a chamber.
- the steel sheet samples are in this situation placed in the chamber at an angle of inclination to the horizontal of 65 to 75°.
- the magnesium content in the melt intended for the coating remains essentially unchanged in the coating.
- the Al content of the coating, in the finished steel strip according to the invention is as a rule 1.8 to 3.2 and in particular 2 to 3 times higher than in the melt.
- An optimum corrosion protection is attained when the coating has an Mg content of 0.4-1.0% by weight, in particular at least 0.5% by weight.
- the melt contains preferably less than 0.15% by weight of aluminium.
- Al contents of the melt which are suitable for standard practice are in this case in the range of 0.12-0.14% by weight.
- the Al content of the melt is preferably at least 0.15% by weight.
- a further surprising property which makes a flat product according to the invention particularly suitable for use in chassis construction becomes apparent when such a sheet or strip is painted. Accordingly, a mandrel bend test carried out on the basis of DIN EN ISO 6860 for sheets or strips according to the invention at room temperature and at ⁇ 20° C. produces good paint adherence capacity. In particular, at a temperature of ⁇ 20° C. there is no indication of paint flaking or of flaking of the coating from the base material.
- a full paint structure was applied onto a steel sheet specimen after alkaline cleaning and phosphating, this structure comprising a 20 ⁇ m thick cathodic dip paint coating, a 32 ⁇ m thick filler paint coating applied onto this and a 40 ⁇ m thick base coating.
- the bending carried out over the conical mandrel did not lead to any detachment of the paint coating at room temperature or at ⁇ 20° C.
- sheets or strips according to the invention have outstandingly good resistance to stone impact.
- stone impact test carried out in accordance with DIN 65996-1B it was possible to demonstrate that, with steel sheets according to the invention, stone impact did not cause any flaking of the coating from the base coat.
- a fine steel strip is subjected to a continuous hot-dip galvanizing process in a galvanizing plant operating at a strip speed of a typical 60 to 150 m/min.
- the sheet or strip to be galvanized is firstly annealed in a furnace, such as a DFF furnace (Direct Fired Furnace) or, preferably, an RTF furnace (Radiant Type Furnace).
- a furnace such as a DFF furnace (Direct Fired Furnace) or, preferably, an RTF furnace (Radiant Type Furnace).
- the sheet or strip runs through the reduction furnace section, in which it is held under a protective gas atmosphere with 3.5-75% hydrogen.
- the temperatures attained in the course of the annealing lie in the range from 720-850° C.
- the sheet or strip annealed in this way is then conducted via what is referred to as a nozzle, with the exclusion of air, into the zinc bath, which is formed from a melt containing 0.05-0.30% by weight Al and 0.2-2.0% by weight Mg, in particular 0.4-1.0% by weight and 0.5-1.0% by weight respectively, the remainder being zinc and unavoidable impurities.
- the thickness of the coating is restricted in an inherently known manner by means of stripper nozzles to a value of a maximum of 3.5 ⁇ m on each side, with the result that, with the flat product obtained according to the invention, the coating weight is restricted to a maximum of 25 g/m 2 per side.
- an inert gas flow can be derived from the stripper nozzles which are used to adjust the thickness of the coating or can be supplied from separate nozzles, which distribute the inert gas in mist fashion over the surface of the bath.
- the entire melt bath can be surrounded by a housing enclosure, in which an inert atmosphere is maintained. Especially suitable as the inert gas for this purpose is nitrogen.
- the slag formation can also be reduced by adjusting the bath temperature to a range of 380-450° C.
- the temperature of the strip can be restricted on immersion to 360-500° C. in order in particular to minimise the inclination to oxidise in the immersion area.
- the coated strip After emerging from the melt bath the coated strip is cooled at a cooling speed of at least 10 K/s.
- the coated is likewise subjected in-line to subsequent heating in the temperature range of 300-600° C., either a redistribution takes place inside the ZnMg coating or through-alloying is achieved into a ZnFeMg coating.
- the melts used to produce such a coating preferably have an Al content of less than 0.15% by weight, and in particular 0.12-0.14% by weight.
- the steel strip annealed in this way is then cooled, such that it is immersed at a melt bath immersion temperature of 465° C. into the melt bath, contained in a housing enclosure under a protective gas atmosphere containing a maximum of 10 ppm oxygen.
- the melt bath consisted of a Zn melt, which as well as unavoidable impurities (e.g. Fe contents, which are drawn into the melt bath by the strip), contained 0.2% by weight Al, and 0.8% by weight Mg. Immersion time was two seconds.
- the coating thickness on the steel strip applied on both sides was adjusted, while still inside the melt bath housing enclosure, by means of stripper nozzles, likewise arranged in the housing enclosure, to a coating thickness of 3 ⁇ m on each side (corresponding to a coating weight of 21 g/m 2 per side).
- the stripping was likewise carried out by means of nitrogen gas.
- the melt bath-coated steel strip obtained had Ra values of 1.8 ⁇ m, with Pc values of 46 cm ⁇ 1 determined in accordance with the StahlEisen Test Datasheet SEP 1940.
- the ball impact hardness test in accordance with the StahlEisen Test Datasheet SEP 1931 was carried out on specimens taken from the finished coated steel strip in order to determine the adherence of the coating and its formability. The result could be classified as Stage 1, which corresponds to good adherence and likewise good ability to forming.
