Rolling is performed by a roll. The austenitic stainless steel strip here
This is because it has better corrosion resistance than ferritic stainless steel and the like.

る。The surface glossiness in Table 1 is a 60-degree specular glossiness tester (HG-6, manufactured by Suga Test Instruments Co., Ltd.) based on the JIS surface glossiness measurement method (Z8741-1997).
The scratchability is defined as the evaluation index, which is based on the concept of a graded evaluation of the degree of scratching from an index of 1 to an index of 10. An evaluation with a scratching index of 1 has the best scratch resistance. That is, the scratch resistance is gradually reduced as the scratch index approaches 10, and the evaluation of the scratch index 10 indicates that the scratch resistance is the worst, that is, the scratch is most likely to be formed. Things,
Thus, as a stainless steel plate used for the top plate of this type of stainless steel sink, as the allowable range of the scratch resistance scratch resistance index, the repetition of the sample experiment has set the scratch index to 6 or less, and the scratch index is lower than 6. If the number is 7 or more, the scratch is very conspicuous and the commercial value is significantly reduced.

５０〜４００以内とすることを見い出した。When the experimental data in Table 1 are verified, samples having a scratch index of 6 or less are samples of B or H excluding A. On the other hand, when the surface gloss is 400 or more, the sample is too glossy and scratches are generated. Conspicuous, it will impair the design,
When the surface glossiness is 50 or less, the surface becomes rough, and other experimental data that dirt, soy sauce, etc. easily adhere to recesses on the surface and are difficult to remove are known. The gloss was found to be within a range of 50 to 400 at a 60 degree gloss value.

When the number of protrusions per 2 is verified, as a sample having a surface glossiness of 50 to 400 at a gloss value of 60 degrees, samples B to H satisfy the above conditions.
When the number of convex portions per 0 mm 2 is less than 5, the surface area of one convex portion becomes large, and the contact area with an object such as a bowl or a cup is increased accordingly, and the convex portion is easily damaged. When the number exceeds 180, the number of enemy recesses inevitably increases, and the increase in the number of recesses makes it easy for dirt and the like to adhere, and it becomes difficult to remove dirt and rust easily. Is known, the number of projections per 100 mm 2 as a desirable unit area is 5 to 1
We found that there were 80.

This is because annealing is performed under an inert gas atmosphere, such as acid pickling for removing scale is not required, and it is possible to obtain luster as it is rolled. In order to further increase the gloss of the brightly annealed stainless steel plate, the stainless steel plate is lightly rolled, whereby a surface finish called so-called BA finish (Bright-Annealing) is performed.

SU) after embossing using a test method according to
It is experimental data of a cast (CASS) test of a stainless steel plate of S304. The test solution of 5% NaCl aqueous solution + acetic acid + cupric chloride (PH3) is sprayed for 8 hours at a room temperature of 50 ° C, and then the spray is performed for 8 hours. The cycle of stopping was repeated, and the corrosion degree of the surface of the embossed material after 48 hours and 96 hours was evaluated by the rating number method (JISZ2371).
(Relative comparison method using annex). Here, the larger the number, the more difficult it is to rust, and the smaller the number, the easier it is to rust. For this reason, the rating numbers are set to 0-9.
