摘要： The invention provides hot-rolled steel strips which, after having been acid-pickled, can be directly used. The strips have no Cr-decreasing layer and no shot blasted marks on their surface and have good corrosion resistance. The invention also provides a technique of efficiently producing the hot-rolled steel strips. A steel slab having a Cr content of from 6.0 to 25.0 wt. % is hot-rolled, then coiled at a temperature not higher than 700° C., then optionally quenched in water immediately after the coiling, then annealing in a reducing atmosphere, and thereafter acid-pickled in a solution of nitric acid/hydrochloric acid.

摘要： A hot-rolled stainless steel strip contains at least 10 wt % Cr and 1.0 wt % or less of Si, and has a controlled scale thickness of not more than 2.5 .mu.m in the surface layer. The average thickness of the Si-containing oxide layer formed in the scale/alloy substitute interface is 0.1 .mu.m or less. The hot-rolled stainless steel strip is produced by hot rolling at an elongation rate of at least 150 or hot rough rolling to form a sheet bar, descaling by spraying superhigh pressure water to the surface of the sheet bar at an impact pressure (p) of 25 kgf/cm.sup.2 or more and a flow rate density of 0.002 l/cm.sup.2 or more, and then finish rolling so that the maximum reduction ratio per pass satisfies certain disclosed criteria.

摘要： 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.
