Description
(1)質量%にてC:0.001〜0.010%、Si:0.01〜0.3%、Mn:0.01〜0.3%、P:0.01〜0.04%、N:0.001〜0.020%、Cr:10〜20%、Nb:0.3〜1.0%、Mo:0.5〜2.0%、Ti:0.05〜0.20%、B:0.0003〜0.0050%を含有し、残部がFeおよび不可避的不純物より成るフェライト系ステンレス鋼板において、総析出物が質量%にて0.05〜0.60%以下であることを特徴とする成形性に優れたフェライト系ステンレス鋼板。
(2)質量%にて、Al:0.005〜0.100%を含有することを特徴とする請求項1記載の成形性に優れるフェライト系ステンレス鋼板。
(3)質量%にて、Cu:0.2〜3.0%、W:0.01〜1.0%:Sn:0.01〜1.0%の1種または2種以上を含有することを特徴とする請求項1または2記載の成形性に優れるフェライト系ステンレス鋼板。
(4)熱延板焼鈍温度を750〜950℃とするか又は熱延板焼鈍なしとして冷間圧延素材を再結晶粒径が1μm以上40μm以下、かつ再結晶率が10〜90%になるように製造し、続いて冷間圧延、1010〜1080℃で焼鈍することことにより(1)〜(3)に記載の成形性に優れたフェライト系ステンレス鋼板を製造する方法。
(5)熱延板焼鈍温度を750〜950℃とするか又は熱延板焼鈍なしとして冷間圧延素材をNb系析出物が体積%にて0.15%以上0.6%以下、かつ直径が0.1μm以上1μm以下、かつ再結晶粒径が1μm以上40μm以下、かつ再結晶率が10〜90%になるように製造し、続いて冷間圧延、1010〜1080℃で焼鈍することにより請求項1〜請求項3に記載の成形性に優れたフェライト系ステンレス鋼板を製造する方法。
r=ln(W0/W)/ln(t0/t) (1)
ここで、W0は引張前の板幅、Wは引張後の板幅、t0は引張前の板厚、tは引張後の板厚である。
平均r値=(r0+2r45+r90)/4 (2)
Δr値=(r0+r90)/4−2r45 (3)
これは、冷延前組織を細粒化すると冷延中に粒界からの変形帯が導入され易くなり、冷延板焼鈍時にr値を向上させる再結晶集合組織が形成され易くなると考えられる。また、冷延前組織の再結晶率が90%以下の場合、熱延組織に起因した未再結晶組織部の方位が異方性低減に優位に作用する。再結晶率が過度に低いと製品の伸びの低下をもたらすため、望ましい再結晶率は10〜90%とした。
