Embodiment 1

[0130] First, stainless steel with the chemical composition shown in Table 1 was smelted and continuously cast using an electric furnace, a converter, and a VOD process to obtain a slab.

[0131] [Table 1]

[0132]

[0133] Next, the continuously cast slab is hot-rolled by a usual method to obtain a hot-rolled steel sheet. And, using the hot-rolled steel sheet as the starting material, each process is carried out in the order of the above-mentioned process (ii) or process (iii), and at the same time, a rough-faced roll is used in the tempering process to form a flat material with a plate thickness of 0.3 mm to 1.5 mm. , as the test material of each embodiment and each comparative example. Table 2 lists the production conditions of these present examples and comparative examples.

[0134] In addition, in Table 2, steel type B and steel type E performed each process by process (ii), and other steel types performed each process by process (iii). In addition, in the finish c...

Embodiment 2

[0158] A gasket was injection-molded on the surface of some of the samples produced in Example 1, and the adhesive adhesion between the stainless steel and the gasket was evaluated.

[0159] When performing injection molding of the gasket, first, the modified olefin-based resin adhesive is pre-coated on the surface of the sample.

[0160] In addition, using a styrene-based thermoplastic elastomer compound, the gasket was injection-molded with an injection molding machine at an injection speed of 0.3 mm / s, an injection pressure of 30 MPa, and a cycle of 30 seconds to adhere to the surface of the sample.

[0161] And, the adhesiveness test was performed as follows.

[0162] In the adhesive test, a penetration peeling of about 1 mm is formed on the pad bonding surface formed on the sample, and a SUS metal wire is passed through the portion where the penetration peeling is formed, and a vertical tensile load is applied to measure the extension of the peeling length. to a load of ...

Abstract

Provided is an austenitic stainless steel sheet which exhibits excellent cleanability, anti-glare properties, and hydrophilicity. In this austenitic stainless steel sheet, which is temper rolled using a dull roll after being subjected to finishing cold rolling and bright annealing, the steel sheet surface has an arithmetic average roughness Ra in a direction orthogonal to the rolling direction of at least 0.2 mu m, but not more than 1.2 mu m. Furthermore, the dull-pattern transfer rate to the steel sheet surface is at least 15%, but not more than 70%. Moreover, micropits which are formed in the steel sheet surface, have a depth of at least 0.5 mu m, and have an opening area of at least 10 mu m2, have a presence density of not more than 10.0 per 0.01 mm2, and an opening area ratio of not more than 1.0%. Furthermore, a film formed on the steel sheet surface is formed from an oxide which mainly consists of SiO2, includes, as film-forming elements other than C, at least Si, N, Al, Mn, Cr, Fe, Nb, Ti, and O, has a Si content of at least 10 atomic%, and has a N content of not more than 10 atomic%.

Description

technical field [0001] The present invention relates to an austenitic stainless steel sheet, a cover member (カバー member) and an austenitic stainless steel obtained by tempering (tempering and tempering pressure rolling) with a matte roll after cold finish rolling (Shishang げ cold intermediate pressure rolling) and bright annealing The method of manufacturing the board. Background technique [0002] Austenitic stainless steel sheets represented by SUS304 and SUS316, and austenitic stainless steel sheets represented by SUS430 are widely used in exterior building materials, interior building materials, and kitchen supplies. [0003] In addition, in these applications, cleaning properties are required in order to facilitate the removal of various dirt or fingerprints attached to the product during manufacture or construction, and various dirt or fingerprints attached during daily use. Fingerprints, handling defects, etc. are not easily conspicuous, and anti-glare properties are...
