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. PM / 粉末鋼 粉末冶金（PM）

PM stands for powder metallurgy. Fine steel powder is consolidated under heat and pressure. This can produce a fine, even carbide structure, but performance still depends on the steel and its heat treatment. The PM label alone does not guarantee a harder, tougher or more chip-resistant knife. 不二越，日本

SRS-13 成分分析

SRS-13 含有什麼？

每種元素對刀鋼性能的貢獻。

SRS-13 元素成分與規格範圍
元素	規格範圍	對刀的作用
Cr鉻	13.0%	Raises corrosion resistance; at roughly 13%+ free chromium the steel qualifies as stainless. Also improves hardenability and wear.
Mo鉬	2.75%	Improves hardenability and toughness, boosts corrosion resistance, and helps the steel hold hardness under heat.
V釩	1.5%	Forms extremely hard vanadium carbides for superior edge retention, and refines the grain for a finer, tougher edge.
C碳	1.3%	The primary hardening element. More carbon means a harder edge that holds longer — but past a point it trades away toughness and rust resistance.
W鎢	1.25%	Forms hard carbides for wear resistance and edge stability, and keeps the steel hard even at elevated temperatures.
Si矽	0.3%	Strengthens the steel matrix and acts as a deoxidiser, improving hardness and resistance to oxidation.
Mn錳	0.3%	Aids hardenability and strength and acts as a deoxidiser in smelting. Too much can reduce toughness.
