本発明は、表面に耐食性に優れた黒色皮膜を有するステ
ンレス鋼とその製造方法に関する。DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a stainless steel having a black film with excellent corrosion resistance on its surface and a method for producing the same.
（従来の技＃ｒ）
ステンレス鋼は、機械的強さ、耐食性等にすぐれている
ので広く使用されているが、美観その他の点で黒色表面
が要求されることが多い。(Conventional Technique #r) Stainless steel is widely used because of its excellent mechanical strength and corrosion resistance, but a black surface is often required for aesthetics and other reasons.
黒色表面を有するステンレス鋼の公知の製法としては、
塗装、黒色クロムメッキ、化成処理等が一般的であるが
、その他に安価な方法として高温加熱による酸化皮膜形
成法がある。しかし、公知の高温酸化法では酸化皮膜を
厚くしても表面の黒色化の程度が低く、また皮膜が厚く
なる程、皮膜が剥離し易くなり、また美観上も優れたも
のが得られにくいという欠点があった。Known manufacturing methods for stainless steel with a black surface include:
Painting, black chrome plating, chemical conversion treatment, etc. are common methods, but another inexpensive method is to form an oxide film by heating at high temperatures. However, with the known high-temperature oxidation method, even if the oxide film is thickened, the degree of blackening on the surface is low, and the thicker the film, the easier it is to peel off, and it is difficult to obtain an aesthetically pleasing product. There were drawbacks.

ものである。(Problems to be Solved by the Invention) The present invention aims to improve the above-mentioned drawbacks of the conventional technology, and is made by applying a predetermined heat treatment to stainless steel containing a specific amount of Ti. Moreover, the present invention provides a stainless steel product having a black surface film that is also aesthetically superior.

それ以上の層を形成するため、全体として薄い皮膜でも
十分な黒色度を有する膜が得られるためと考えられる。(Means for solving the illumination point) The gist of the present invention is to heat-treat stainless steel with a Ti content of 0.1 to 1.5 wt% under the conditions within rectangle ABCD in the attached drawings. The present invention relates to a method for producing colored stainless steel and a black temper colored stainless steel obtained by the method. The reason why a black film with good adhesion is formed on the surface of stainless steel according to the present invention is that Ti is oxidized on the surface of the stainless steel at the beginning of the heat treatment, and then Cr oxide is formed underneath. However, since two or more layers are sequentially formed, a film having sufficient blackness can be obtained even if the film is thin as a whole.
次に、本発明を実施例によフてより具体的に説明する。Next, the present invention will be explained in more detail with reference to Examples.

ステンレス鋼では黒色度が低く、密着性も恕い。(Example) Table 1 shows the chemical composition of stainless steel used in the test and 900
The relationship with blackness when heated in the atmosphere for 30 minutes at ℃ is shown. Here, each stainless steel plate is cold rolled to 0°8mm, annealed at 800-900°C, pickled, #320
Emery paper was used after polishing with acetone. 1st
As you can see from the table, Ti-containing stainless steel has a rating of 900
Heating for 30 minutes at °C produces an oxide film with a high degree of blackness on the surface and good adhesion. On the other hand, stainless steel that does not contain Ti has a low degree of blackness and poor adhesion.

Table 2 shows the results of checking the time. As a sample, the 1st
Tests were conducted using No. 3 and No. 4 in the table, changing the heating conditions. For No. 013 and No. 4, almost no difference was observed in the results of the blackening test even if the heating conditions were changed, so they are listed together in Table 2. As shown in Table 2, the degree of blackness and adhesion of the oxide film change depending on the heating temperature and time. Appropriate heating temperature and time ranges were determined from Table 2 and are shown in the attached drawings. Note that each vertex of quadrilateral ABCD is A(97
5℃, 3 minutes) B (1150℃, 3 minutes) C (800℃, 1
200 minutes) D (800°C, 120 minutes), indicating that stainless steel containing 0.1 to 1.5% Ti within this range produces an oxide film with good adhesion and a high degree of blackness. ing. If the Ti content is less than 0.1%, no blackening occurs;
．． If it exceeds 5%, hot workability will deteriorate.
