不鏽鋼
不鏽鋼
"Stainless" means stain-resistant, not stain-proof. In kitchen use, the steel can still discolour or pit if exposed to acidic environments — citrus, vinegar, or salt water — for extended periods. Wash and wipe dry after every use, and avoid leaving the blade soaking in water. With basic care, a stainless knife is very low-maintenance and a great everyday choice. 愛知，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.

AUS-8，常被稱為「鉬釩鋼」，是一種日本不鏽鋼，以價格親民、易於研磨及優異的耐腐蝕性而備受好評。由於其均衡的特性，特別推薦給經驗較淺的使用者。添加鉬和釩後，AUS-8具備更強的韌性、硬度與耐用度，屬於中高階鋼材。它與440鋼相當，但在硬度與耐腐蝕性上更為出色。經過適當的深冷處理，可進一步提升其鋒利保持性與韌性，使AUS-8成為刀具製造商與追求品質和性能的使用者極具成本效益的選擇。

AUS-8 成分分析
AUS-8 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 | 13.0–14.5% | Raises corrosion resistance; at roughly 13%+ free chromium the steel qualifies as stainless. Also improves hardenability and wear. |
| Si矽 | 1.0% | Strengthens the steel matrix and acts as a deoxidiser, improving hardness and resistance to oxidation. |
| C碳 | 0.7–0.75% | The primary hardening element. More carbon means a harder edge that holds longer — but past a point it trades away toughness and rust resistance. |
| Mn錳 | 0.5% | Aids hardenability and strength and acts as a deoxidiser in smelting. Too much can reduce toughness. |
| Ni鎳 | 0.49% | Improves toughness and ductility without sacrificing hardness, and adds a small boost to corrosion resistance. |
| Mo鉬 | 0.1–0.3% | Improves hardenability and toughness, boosts corrosion resistance, and helps the steel hold hardness under heat. |
| V釩 | 0.1–0.26% | Forms extremely hard vanadium carbides for superior edge retention, and refines the grain for a finer, tougher edge. |
| P磷 | 0.04% | An impurity from smelting. Even small amounts promote brittleness, so steelmakers keep it as low as possible. |
| S硫 | 0.03% | An impurity that reduces toughness and promotes brittleness; only ever added deliberately in free-machining steels. |
