問題があった。2. Description of the Related Art Materials for disc brakes such as motorcycles need to have rust resistance and abrasion resistance. Therefore, in general, Rockwell hardness (H R C) a martensitic stainless steel which is adjusted to the range of 32-38 are used. By the way, as stainless steel conventionally used for motorcycle disc brakes, SUS 420J1 of 0.2 wt% C, 0.1%
Medium-carbon martensitic stainless steel such as SUS420J2 of 3 wt% C, and 0.3 wt% C-16 wt% Cr. These stainless steels are usually quenched at 850 to 50 ° C. to provide properties as brake materials, and then 550 to 65
Manufactured by heat treatment of tempering at 0 ° C. Although the stainless steel manufactured by such a conventional technique has a hardness as a disc brake, it has a problem that rust resistance is inferior because a low Cr concentration region is generated in the heat treatment step.

It cannot be said that the techniques proposed in JP-A-51-20712 and JP-A-51-20713 still sufficiently meet the recent demands for severe rust resistance. On the other hand, the technique proposed in Japanese Patent Application Laid-Open No. 57-198249 is excellent in rust resistance, but is a quenched material. When the temperature exceeds ℃, there is a problem that hardness is reduced due to tempering. This problem,
In particular, the heat generation is larger in a large motorcycle, so that it becomes more serious. Conventionally, in order to avoid a rise in temperature due to heat generation, measures have been taken to increase the heat capacity by increasing the size or thickness of the disk, or to manufacture and assemble the outer periphery of the disk as a separate part from the center. However, both methods are associated with higher costs. Also, even if such a measure is adopted, the hardness may be reduced, and it cannot be said to be a perfect measure.

【発明の実施の形態】以下、本発明における構成要件を
上記範囲に限定した理由について説明する。 Ｃ：0.25〜0.40wt％ Ｃは、所定の耐熱劣化性を付与するために必要な元素で

て、Ｃ量は0.25〜0.40wt％の範囲とする。DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The reasons for limiting the constituent elements of the present invention to the above ranges will be described below. C: 0.25 to 0.40 wt% C is an element necessary for imparting a predetermined resistance to heat deterioration. If the C content is less than 0.25 wt%, sufficient heat deterioration resistance cannot be obtained, and a single ferrite phase will not be formed during the quenching, and a uniform ferrite material cannot be realized. On the other hand, if it exceeds 0.40 wt%, the deterioration of rust resistance becomes remarkable, and the quenching distortion increases. Therefore, the C content is in the range of 0.25 to 0.40 wt%.
【００１２】Si：1.0 wt％以下 Siは、フェライト生成元素であり、その量が1.0 wt％を
超えると硬さの確保が困難になるので、1.0 wt％以下、
好ましくは0.4 wt％以下の範囲とする。Si: 1.0 wt% or less Si is a ferrite-forming element, and if its amount exceeds 1.0 wt%, it becomes difficult to secure hardness.
It is preferably in the range of 0.4 wt% or less.
【００１３】Mn：1.1 〜2.5 wt％ Mnは、耐銹性を確保するために必要な元素であり、少な
くとも1.1 wt％は必要である。しかし、2.5 wt％を超え
て添加すると、高温での耐酸化性が低下し、製造工程で
の多量のスケール発生、酸洗時の表面肌荒れを招く。よ
って、Mn添加量は1.1 〜2.5 wt％の範囲とする。Mn: 1.1 to 2.5 wt% Mn is an element necessary for ensuring rust resistance, and at least 1.1 wt% is required. However, if it is added in excess of 2.5 wt%, the oxidation resistance at high temperatures is reduced, and a large amount of scale is generated in the production process and the surface is roughened during pickling. Therefore, the amount of Mn added is set in the range of 1.1 to 2.5 wt%.
【００１４】Cr：12.0〜16.0wt％ Crは、耐銹性を確保するために必要な元素であり、少な
くとも12.0wt％は必要であるが、16.0wt％を超えると不
均一組織になるので、12.0〜16.0wt％の範囲で添加す
る。Cr: 12.0 to 16.0 wt% Cr is an element necessary for ensuring rust resistance. At least 12.0 wt% is necessary, but if it exceeds 16.0 wt%, a non-uniform structure is obtained. It is added in the range of 12.0 to 16.0 wt%.
【００１５】Mo：0.3 〜1.5 wt％ Moは、耐銹性および耐熱劣化性の向上に有用な元素であ

1.5 wt％を超えると焼き入れ時の組織にフェライト相が
生じて、硬さ低下を招き、十分な耐熱劣化性が得られな
くなる。よって、Mo量は0.3 〜1.5 wt％の範囲で添加す
る。Mo: 0.3 to 1.5 wt% Mo is an element useful for improving rust resistance and heat deterioration resistance, and requires addition of 0.3 wt% or more. On the other hand,
If the content exceeds 1.5 wt%, a ferrite phase is formed in the structure at the time of quenching, causing a decrease in hardness and making it impossible to obtain sufficient heat deterioration resistance. Therefore, the amount of Mo is added in the range of 0.3 to 1.5 wt%.
【００１６】Ｖ：0.1 〜0.5 wt％ Ｖは、必要な耐銹性を確保するために0.1 wt％以上の添
加を必要とする。しかし、0.5 wt％を超えて添加する
と、焼入れ硬さが低下して、十分な耐熱劣化性が得られ
なくなるので、上限を0.5 wt％とする。V: 0.1 to 0.5 wt% V needs to be added in an amount of 0.1 wt% or more to secure necessary rust resistance. However, if it is added in excess of 0.5 wt%, the quenching hardness is reduced and sufficient heat deterioration resistance cannot be obtained, so the upper limit is made 0.5 wt%.
【００１７】Ni：0.5 wt％以下、Cu：0.5 wt％以下 NiおよびCuは、いずれも耐銹性の向上に有用な元素であ

If it exceeds 0.5 wt%, the hardenability decreases. Therefore, Ni,
Cu is added in a range of 0.5 wt% or less.

If the content exceeds 0.0030 wt%, the rust resistance is reduced.
a and Mg are each added in a range of 0.0030 wt% or less.
