Chromax Chromax 鋼
硬度
洛氏硬度(HRC) measures how resistant a steel is to permanent deformation. For kitchen knives:
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.

Chromax是一種傳統熔煉的不鏽鋼，並非粉末冶金（PM／SG2／R2類型）。
它由武生特殊鋼公司生產（與VG10、SG2／R2等為同一製造商）。
類型：傳統鑄錠鋼材（非粉末冶金）
類別：高鉻不鏽鋼
特性：
良好的抗腐蝕性（高於VG10）
易於研磨
比許多粉末冶金鋼材更具韌性、較不易脆裂
鋒利保持度中等（低於SG2／R2）
