Definitions
- the invention relates to a coated steel sheet or strip with a base layer consisting of steel, on whose at least one upper side by hot dip coating a zinc coating is applied.
- the zinc coating ensures high corrosion resistance. This is the larger, the thicker the coating is.
- the red test carried out on a bare, unpainted sample in accordance with DIN 50021 results in red rust already after 24 hours at a coating run of 25 g / m 2 , while red coating occurs at a coating application of 70 g / m 2 after 120 hours arises.
- the thickness of the coating required in the prior art for sufficient corrosion resistance involves problems in weldability. This is especially true if, by means of laser welding at high welding speeds, a through-welding in the lap joint is to be produced without a minimum gap, as required, in particular, in the field of building automobile bodies or in the field of household technology.
- the seam produced by such a weld should be free of through holes, have a substantial crater freedom and have no open pores.
- the object of the invention was therefore to provide a flat steel product which has an optimum combination of high corrosion resistance and optimized weldability and which is particularly suitable for use as a material for automotive body construction or for the construction of household appliances.
- a coated steel sheet or strip which has a base layer made of steel, on the at least one upper side of which a hot dip coating is applied, which consists of a layer of 0.05-0.30% by weight of Al and 0.2-2.0% by weight of Mg, balance zinc and unavoidable impurities existing melt is formed and each side with a coating thickness of at most 3.5 microns and a maximum coating weight of 25 g / m 2 ensures that the steel sheet shows the first formation of red rust at the earliest after 250 hours in the salt spray test carried out according to DIN 50021-SS.
- a hot-dip-coated flat steel product according to the invention has surprisingly good corrosion resistance at a maximum coating weight of 25 g / m 2 per side, minimized in comparison with the prior art.
- the low coating weight and the associated low thickness of the coating of a maximum of 3.5 microns each side in combination with the high corrosion resistance makes inventive sheet or strip particularly suitable for the production of components that are produced by welding of individual sheet metal elements.
- elements for automobile bodies or home appliance technology can be produced with sheet steel produced according to the invention by welding the individual sheet metal parts formed from sheet metal or strip according to the invention by laser welding at high welding speeds economically and with optimum results.
- the corrosion resistance of the invention is based on a salt spray test according to DIN 50021-SS in a Corrosion short-time test method on bare, unpainted steel sheet determined, in which a neutral 5% NaCl solution is continuously sprayed in a chamber at a temperature of 35 ⁇ 2 ° C as an attacking agent.
- the steel sheet samples are placed in the chamber with an inclination angle of 65 to 75 ° to the horizontal. In practical tests carried out in this way, it has been found that sheets and strips coated according to the invention regularly show first red rust formation only after a test duration of 300 hours.
- the magnesium content contained in the melt intended for the coating is found essentially unchanged in the coating.
- the Al content of the coating in the finished steel strip according to the invention is generally 1.8 to 3.2, in particular 2 to 3 times, higher than in the melt.
- Optimum corrosion protection is achieved if the coating has a Mg content of 0.4-1.0% by weight, in particular at least 0.5% by weight.
- the melt preferably contains less than 0.15% by weight of aluminum. Practical Al contents of the melt in this case are 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 full-scale coating comprising a 20 ⁇ m thick cathodic dip coating, a 32 ⁇ m thick surfacer coat layer applied thereto and a 40 ⁇ m thick basecoat film was applied to a steel sheet sample after alkaline cleaning and phosphating.
- the bending over the conical mandrel performed neither at room temperature nor at -20 ° C to a detachment of the paint layer.
- sheets or tapes according to the invention have excellent resistance to stone chipping.
- DIN 65996-1B it was possible to demonstrate that, in the case of steel sheets according to the invention, no flaking of the coating from the base layer is caused by rockfall.
- a steel fine strip in a galvanizing plant which is traversed at a strip speed of typically 60 to 150 m / min, is subjected to a continuously running strip hot-dip galvanizing process.
- This will be too galvanizing sheet or strip first in an oven, for example a DFF furnace (Direct Fired Furnace) or, preferably, a RTF furnace (Radiant Type Furnace) annealed. Following the oven, the sheet or strip passes through the reduction furnace section, where it is maintained under a protective gas atmosphere of 3.5-75% hydrogen.
- the temperatures achieved during annealing are in the range of 720 - 850 ° C.
- the thus annealed strip or sheet is then passed through a so-called proboscis under exclusion of air in the zinc bath, by a 0.05 to 0.30 wt .-% Al and 0.2 to 2.0 wt .-% Mg, in particular 0.4 to 1.0 wt .-% or 0.5 to 1.0 wt .-%, remainder zinc and unavoidable impurities containing melt is formed.
- the thickness of the coating is limited in a conventional manner by means of stripping nozzles to a value of 3.5 microns maximum page, so that the resulting flat product according to the invention, the maximum coating weight of 25 g / m 2 per side is limited.
- an inert gas stream may originate from the wiping nozzles used to adjust the coating thickness, or may be discharged from separate nozzles which disperse the inert gas over the bath surface.
- the entire melt bath can be surrounded by an enclosure in which an inert atmosphere is maintained. Nitrogen is particularly suitable as inert gas for this purpose.
- Slag formation can also be reduced by adjusting the bath temperature to a range of 380-450 ° C.
- the belt temperature during immersion can be limited to 360 - 500 ° C in order to minimize the tendency to oxidation, especially in the immersion area.
- the coated tape After exiting the melt bath, the coated tape is at a cooling rate of at least 10 K / s. cooled.
- the melts used to produce such a layer preferably have an Al content of less than 0.15% by weight, in particular 0.12-0.14% by weight.
- the thus annealed steel strip was then cooled so that it is immersed in the molten bath immersion temperature of 465 ° C in the molten bath held in an enclosure under a maximum of 10 ppm oxygen containing inert gas atmosphere.
- the molten bath consisted of a Zn melt containing, in addition to unavoidable impurities (e.g., Fe levels being dragged through the belt into the molten bath), 0.2 wt% Al, 0.8 wt% Mg.
- the dive time was two seconds.
- the layer thickness of the coating applied on both sides of the steel strip has been adjusted within the Schmelzenbadeinhausung by means also arranged in the housing Abstreifdüsen to a coating thickness of 3 microns per side (corresponding to a weight of 21 g / m 2 each side) ,
- the stripping was also done by means of nitrogen gas.
- the steel band has been trained.
- the resulting hot dip coated steel strip had Ra values of 1.8 ⁇ m at Pc values of 46 cm -1 determined according to SEP 1940 Steel Iron Test Sheet.
- the samples taken from the finished coated steel strip were subjected to the ball impact test according to the steel-iron test sheet SEP 1931 was performed to determine the adhesion of the cover and its formability. The result could be assigned to the level 1, which corresponds to a good adhesion and also good formability.
- thermoforming test in which a hat-shaped component was drawn from a round sheet-steel plate obtained according to the invention in a suitable tool, a very low abrasion of not more than 0.45 g / m 2 resulted.
- the salt spray test carried out on a unpainted blank in the manner described in accordance with DIN 50021 SS gave a first formation of red rust only after a spraying time of 312 hours.
- a conventional Zn coating with a coating weight of 25 g / m 2 per side provided sheets showed after 24 hours, a red rust formation.
