Definitions
- the invention relates to a process for coating steel strips with (in wt .-%) C 0.04 - 1, 0; Mn 9.0-30.0; AI 0.05 - 15.0; Si 0.05-6.0; Cr ⁇ 6.5; Cu ⁇ 4; Ti + Zr ⁇ 0.7; Nb + V ⁇ 0.5, balance iron including unavoidable steel-accompanying elements, in which the steel strip undergoes a final annealing and then electrolytically coated with a coating formed from pure zinc or a zinc alloy.
- the steel strip can be both cold and hot rolled.
- the invention relates to a steel strip, which is a corresponding
- Steels with high contents of manganese, aluminum and / or silicon are suitable because of their favorable properties with respect to elongation and strength for use in transport vehicles, in particular in the field of automotive and as HSD ® - known steels (High Strength and Ductlity).
- these steels are characterized by a significantly lower specific weight compared to conventional steels, so that the use of these lightweight steels contributes to a significant weight reduction in the body shop.
- Steels with high manganese contents of 7 - 30 wt .-% are z. B. from DE 102 59 230 A1, DE 199 00 199 A1 and DE 10 2004 061 284 A1.
- Flat products produced from these steels exhibit high uniformity at high strengths.
- these advantages are offset by the fact that steels with higher manganese contents are prone to pitting and surface corrosion and have little resistance to hydrogen-induced stress corrosion cracking without the addition of aluminum and / or silicon. Therefore, it has already been proposed, even flat products high-manganese steels in a conventional manner to provide a metallic coating that protects the steel from corrosive attack.
- WO 2007/075006 A1 a high-manganese steel is proposed, from which a flat product is produced in a known manner, which is optionally coated electrolytically or by hot dipping after the last final annealing.
- WO 2006/042930 A1 likewise proposes a high-manganese steel whose flat product produced therefrom is coated by means of a hot dip treatment.
- Liquid metal embrittlement in the weld zone during welding of galvanized materials is characterized.
- Beam welding process understood in which in addition to the base material of the zinc coating is locally liquefied.
- the Al intermediate layer is intended to prevent that zinc from the hot dip coating penetrates into the structure of the steel material during welding and
- Liquid metal embrittlement leads.
- the application of such an intermediate layer is very costly, in addition, no statement is made about improving the weldability of electrolytically galvanized high manganese steels.
- the stated object is achieved in such a way that in steel strips the (in wt .-%) C 0.04 - 1.0; Mn 9 - 30; AI 0.05 - 15.0; Si 0.05-6.0; Cr ⁇ 6.5; Cu ⁇ 4%; Ti + Zr ⁇ 0.7;
- the grain boundary attack by the molten zinc can be effectively prevented when welding high-manganese steels.
- the annealing invention u. a. the aluminum contained in the steel with the nitrogen from the annealing atmosphere near the surface to aluminum nitride.
- the near-surface nitrides formed during the annealing of the steel strip are also formed in the region of the grain boundaries, whereby an effective barrier is created which prevents infiltration by the molten zinc during welding.
- An essential criterion for an improved weldability of high-manganese steels is a defined nitriding depth which, on the one hand, must be so high that one
- the thickness of the nitriding layer in the near-surface region of the base material should be at least 1 ⁇ m but should not exceed a thickness of 50 ⁇ m.
- Nitriding depths between 5 and 25 ⁇ m, and in particular between 5 and 15 m, have proven to be advantageous in terms of improved weldability and only a small amount
- the inventive design of the Aiuminiumnitrid harsh is achieved at annealing temperatures from about 850 ° C. Higher annealing temperatures reduce the annealing time required to reach the required nitriding depth. If the annealing temperature is lower, the annealing time must be extended accordingly to set the same nitriding depth. Annealing temperatures of 900-950 ° C have proven to be advantageous in the experiments on cold tapes, wherein the required nitriding depths have been established in the usual throughput times in continuous-annealing plants.
- Annealing atmosphere and the corresponding adjustment of the annealing parameters very cost, with known and existing large-scale units realize.
- the hot strip is pickled in the usual way, then cold rolled and the
- the tape is subjected to alkaline cleaning and surface activation before electrolytically zinc is applied in a known manner.
- the cold-rolled strip galvanized in this way satisfies the requirements for adequate corrosion protection and, in particular, can also be welded well without liquid-metal embrittlement occurring.
