- the disclosed steel exhibits mechanical strength, ductility, wear and corrosion resistance, and no ferromagnetism.
- a disadvantage is that during the production of these alloys during solidification, a primary ferrite formation takes place, which can lead to leakage of nitrogen during melting and / or welding.
- the present invention is a corrosion-resistant austenitic steel containing in addition to iron, each based on 100 mass percent,
- the austenitic steel according to the invention exhibits TWIP (Twinning Induced Plasticity) properties and good corrosion resistance.
- TWIP winning Induced Plasticity
- An essential feature of this TWIP steel is a plasticity by formation of twin grain boundaries with a To obtain good corrosion resistance, that is, a steel that forms numerous twin grain boundaries in its microstructure upon deformation, thereby strongly and uniformly solidified, in the tensile test high technical strains and remains completely austenitic without formation of martensite.
- the steel of the present invention has a stabilized austenitic structure formed by the combination of the main alloying elements Fe, Mn and Cr and the interstitial elements C and N.
- the steel according to the invention shows an elongation at break of more than 90%, a yield strength of more than 400 MPa and a tensile strength of more than 900 MPa. Due to the combination of high elongation at break and yield strength, the steel according to the invention is extremely deformable.
- the alloys according to the present invention show after targeted deformation no detectable by X-ray diffraction formation of ⁇ -martensite or e-martensite.
- the alloy according to the invention in the abovementioned proportions of Cr, Mn, C and N, allows primary austenitic solidification, whereby a melt is obtained, from which nitrogen does not escape both during solidification and / or welding.
- the alloy can thus be produced under normal pressure and also processed.
- the alloy according to the invention shows a stable austenitic structure which prevents the formation of ferrite.
- the alloy metal Cr and the existing N cause higher corrosion resistance compared to the prior art TWIP steels.
- the individual proportions of the alloy metals Cr and Mn and of the additives N and C are set in such a ratio that the amount of Cr not only improves the solubility of N in the melt, but also has an advantageous effect on the corrosion resistance of the alloy without During the solidification of the melt primarily ferrite forms.
- the formation of ferrite is disadvantageous because it would result in a lower solubility for nitrogen and thus a pore formation.
- the weldability of the alloy according to the invention is also positively influenced. by avoiding nitrogen outgassing during solidification after fusion welding, and avoiding the formation of precipitates in the process - A - subsequent cooling of the solid material of the weld and the heat affected zone to room temperature. This is above all technologically important because after welding, the material cools relatively slowly and formation of precipitates at the weld and in the heat affected zone is undesirable.
- the amount of Mn improves the ductility (plasticity, deformability).
- the other ingredients C and N improve the mechanical properties and the corrosion resistance without forming nitrides and carbides.
- the inventive ratio of C and N allows fully austenitic solidification without gases escape during melting or carbides or nitrides are formed during accelerated cooling.
- the solubility for the desired amount of nitrogen in the melt is preferably given at 1500 0 C and 1 bar pressure.
