半不鏽鋼
半不鏽鋼
Semi-stainless steels sit between carbon and full stainless. They will rust if left wet or neglected, but under normal use they tend to develop a patina — a dark, protective layer — rather than forming aggressive surface rust. Rinse and wipe dry after use and you will rarely have issues. Much more forgiving than true carbon steel, while still offering excellent cutting performance. 日立特殊鋼，日本

硬度
洛氏硬度(HRC) 衡量鋼材抵抗永久變形的能力。就廚刀而言：
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.

YXR7 成分分析
YXR7 含有什麼？
每種元素對刀鋼性能的貢獻。
| 元素 | 規格範圍 | 對刀的作用 |
|---|---|---|
| Cr鉻 | 5.0% | Raises corrosion resistance; at roughly 13%+ free chromium the steel qualifies as stainless. Also improves hardenability and wear. |
| Mo鉬 | 5.0% | Improves hardenability and toughness, boosts corrosion resistance, and helps the steel hold hardness under heat. |
| V釩 | 1.1% | Forms extremely hard vanadium carbides for superior edge retention, and refines the grain for a finer, tougher edge. |
| W鎢 | 1.1% | Forms hard carbides for wear resistance and edge stability, and keeps the steel hard even at elevated temperatures. |
| C碳 | 0.8% | The primary hardening element. More carbon means a harder edge that holds longer — but past a point it trades away toughness and rust resistance. |
