Recently, in basic applied research in future energy development fields such as nuclear-combined Φ power generation, large superconducting magnets are required for proton and electron acceleration and plasma confinement. The need for non-magnetic steel for these structural members is increasing.0%
In addition, from the viewpoint of magnetic loss and low-temperature toughness, a nine-layer structure in which three or less thin plates are stacked is also attracting attention. If such plates were manufactured by hot rolling, the load on the pressing machine would be extremely high, and the shape would be poor in flatness, causing problems with consistency when stacking the plates. The inventors conducted research with the aim of compensating for the drawbacks of the conventional method as well as obtaining a material that is inexpensive and has even higher strength.The inventors found that by replacing the set with M, an inexpensive and stable material was developed. Magnetic steel can be obtained, and by applying cold rolling of 2096 or more after hot rolling, a material with excellent υ shape and high strength can be obtained by refining the grains after final annealing. I found it.

Mn is an effective element for rounding to obtain an austenite phase, and Mn of 9 or more is required to obtain nonmagnetism in austenite. In addition, if it exceeds 35%, the effect saturates in the range of 9 to 35%.90 Cr, like Mn, is an element necessary to obtain a stable austenite phase, and below that, Iil is 0. .5-. However, if the content exceeds 19s, the ferrite phase tends to grow, so the upper limit is set at 19%.It is also an element that improves Cr1d corrosion resistance, and from that point of view as well, the above range is preferable.

According to the present invention, Kurei-Kan pressed silver steel plates and steel strips are manufactured as follows. That is, f#rI! is produced using a converter, a melting furnace with an electric capacity of 1 fathom, and, if necessary, a vacuum de-fusing device.
! The resulting molten steel is made into steel billets through ingot making or continuous casting. Subsequently, this steel piece is hot rolled to form a hot rolled steel strip. The finishing temperature at this time is preferably 500°C or higher.
Further, cooling after hot rolling may be performed by any cooling method such as air cooling or water cooling. Thereafter, the hot-rolled steel strip is softened and annealed if necessary, and then cold-rolled once or twice. In addition, the Yanghesha rolling reduction ratio of one cold rolling is 2096 or more,
In the case of two-time cold rolling, the rolling reduction ratio of the second cold air is set to 20- or more. Furthermore, this cold rolled copper strip is heated to 800 to 1150℃.
The product is then annealed to produce a cold rolled copper strip or steel sheet product. Cooling after annealing is water cooling - 58 tL, but air cooling may be used.

The manufacturing method using cold rolling, which is a feature of the present invention, is different from the conventional method using hot rolling kLK.
It is possible to control the austenite crystal grains after subsequent annealing. The strength of austenite depends on the crystal grain size, and the finer the crystal grains, the higher the strength. That is, cold rolling increases strain accumulation due to K, and many recrystallization nuclei are generated during annealing. Furthermore, due to dislocations introduced by cold rolling and lamination paths, fine carbon and nitrides precipitate within the grains during heating and holding during annealing.

As mentioned above, by performing cold rolling, many recrystallized nuclei are generated during annealing of the cold rolled copper strip, and the growth of crystal grains is suppressed by fine precipitates. It is possible to obtain crystal grains with high strength. In this way, the present invention Fi is made into complete austenite, and if necessary, grain refining elements such as Nb and T1 are added to it, and this is combined with a cold rolling process to increase the strength of the material. It is something.

Figure 1 shows 25 IsMn -511cr-11Ni -
The mechanical properties of 0.04% N steel were hot rolled, then cold rolled at various rolling reductions, further annealed at 1000° C. for 1 minute, and then water cooled. Cold-rolled products have finer grains and higher strength than non-cold-rolled products. Also,
Even if cold rolling is performed, if the reduction ratio is less than 2011, sufficient strain will not be accumulated, and less recrystallization nuclei will occur during annealing.
Carbon and nitrides do not precipitate finely, so the crystal grains become coarse and the strength is low.Therefore, the rolling reduction in cold rolling immediately before annealing must be 2091 or more. At the above rolling reduction ratio, fine crystal grains can be stably obtained.

Figure 2 shows 25% klh -51ICr -111Ni
The mechanical properties of -0.04$N steel are shown after cold pressure grinding, annealing at various temperatures for 1 minute and 5 minutes, and then water cooling. If W8 is dulled at less than 800℃, it will not be recrystallized, and the elongation will be low and the workability required as a thin plate will be poor.
If the temperature exceeds 150°C, the crystal grains become coarse and the strength required as a structural material decreases. This tendency shows that when the shell time is annealed for less than 5 minutes, the difference due to the annealing time is not clear, and when the shell time is annealed for 5 minutes, it is inappropriate in terms of productivity and processability. As mentioned above, the annealing temperature is t'1
A temperature of 800 to 1150°C is appropriate.
