Abstract: An austenite stainless steel plate having both excellent surface brightness and superior corrosion resistance, without polishing after finish annealing and pickling for descaling of the strip. The steel plate contains Si 0.02 to 0.2 wt % together with Si oxides at 1.0 wt % or less in the surface layer part in the 10 .mu.m depth from the surface. The depth of the intergranular groove in the surface layer part is 0.1 .mu.m or more to 0.5 .mu.m or less. Furthermore, the steel plate contains Al of 0.005 wt % or less and 0 of 0.006 wt % or less. The Al oxides are contained at 0.1 wt % or less in the surface layer part in the 10 .mu.m depth from the surface.

Abstract: This invention relates to a process for the production of stainless steel sheets and proposes a process for the production of stainless steel sheets having a more excellent corrosion resistance as compared with the conventional one without trimming the steel sheet surface after annealing-pickling by preventing the chapping of steel sheet surface created in the production of present stainless steel sheet, particularly stainless steel sheets having extreme-low amounts of C, S, O.For this purpose, according to the invention, a starting material of stainless steel containing C: not more than 0.01 wt %, S: not more than 0.005 wt % and O: not more than 0.005 wt % is subjected to a hot rolling at a draft below 830.degree. C. of not less than 30%, cooled at a cooling rate of not less than 25.degree. C. sec, coiled below 650.degree. C. and then annealed and pickled.

Abstract: A graphite precipitated hot-rolled steel plate having excellent bending workability and hardenability, the graphite precipitated hot-rolled steel plate comprising: 0.1 to 1.0% (by weight percent) C; 0.05 to 1.0% (by weight percent) Mn; 3 to 50 ppm B; 200 ppm or less N the quantity of which is three times or more the quantity of B; and a balance of Fe and unavoidable impurities, wherein graphite the diameter of which is 5 .mu.m or less is precipitated in such a manner that distance between graphite particles is at a distance of 5 .mu.m or longer.
