ステンレス鋼 ステンレス鋼

Hardness ? Rockwell C Hardness(HRC) は、鋼材の永久変形に対する耐性を示す指標です。包丁においては：

55–58 HRC — Soft. Easy to sharpen and forgiving of rough use, but dulls faster. Typical of most German knives.
59–61 HRC — Balanced. Good edge retention with manageable sharpening. Common in mid-range Japanese knives.
62–64 HRC — Hard. Excellent edge retention, holds a very fine edge. Requires more care and a fine stone to sharpen.
65+ HRC — Very hard. Exceptional edge longevity but more brittle — more prone to chipping if used roughly.

Higher is not always better — it depends on how you use and maintain your knife.

青木刃物製作所のステンレス鋼ラインは、実用的な性能、耐久性、手入れのしやすさのバランスを取るよう設計されたステンレス鋼（Inox＝フランス語のinoxydableに由来）を使用しています。一般的に57〜59 HRC程度に焼入れされており、鋭い切れ味を持ちながらも研ぎやすく、硬くて脆い鋼材よりも扱いやすいのが特徴です。ステンレス素材により錆や変色に強く、伝統的な炭素鋼に比べて手入れの手間を省きたい方に適しています。永切れは中程度で高級炭素鋼や粉末鋼には及ばないものの、日常のキッチン作業において抜群の使い勝手を誇り、信頼性と手軽さを求めるご家庭の料理人やプロの方に特に最適なシリーズです。

    13.5% 10.1% 6.8% 3.4% 0
    C Carbon 0.5%
    Primary hardening element. Raises hardness and wear resistance — but too much increases brittleness and corrosion susceptibility. As a reference: German 1.4112 (~0.5%) sits at the low end; VG-10 (~1.0%) is a common mid-range; SG2 (1.25–1.45%) and ZDP-189 (~3.0%) represent high and extreme ends respectively.
    C
    0.5%
    Cr Chromium 13.5%
    Raises corrosion resistance; 13%+ qualifies steel as stainless. Also improves hardenability and wear resistance. In kitchen use, higher chromium levels contribute to a slight drag or sticking sensation when cutting — a trade-off for the rust resistance it provides.
    Cr
    13.5%
    V Vanadium 0.2%
    Forms extremely hard carbides for superior edge retention. Also refines grain structure, improving toughness.
    V
    0.2%
    Mo Molybdenum 0.3%
    Improves hardenability and toughness. Boosts corrosion resistance and helps the steel hold hardness under heat.
