Stainless Stainless Steel

"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 / Powder Steel 분말야금(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. 나치 후지코시, 일본

SRS-13 강은 경도, 인성 및 내식성의 뛰어난 균형으로 유명한 고급 분말야금 스테인리스강입니다. 고탄소강과 스테인리스강의 장점을 결합하여 주방용 칼에 다재다능한 선택지가 됩니다. SRS-13은 녹 방지 기능을 위한 상당량의 크롬과 함께 날붙이 유지력 및 내마모성을 높이는 탄소, 몰리브덴, 바나듐을 함유하고 있습니다. 이 강은 높은 수준까지 경화될 수 있어, SRS-13으로 제작된 칼은 오래 지속되는 예리하고 내구성 있는 날을 구현할 수 있습니다. 분말야금 공정은 균일한 입자 구조를 만들어 미세한 날을 세우고 장기간 사용 중에도 이를 유지하는 능력에 기여합니다. SRS-13 강은 성능, 관리 용이성 및 수명의 조화를 추구하는 전문 셰프와 요리 애호가들에게 어필하며 프리미엄 주방용 칼에 선호됩니다.

What's in SRS-13

What each element does in your knife.

SRS-13 element composition
Element	Composition	What it does in your knife
CrChromium	13.0%	Raises corrosion resistance; at roughly 13%+ free chromium the steel qualifies as stainless. Also improves hardenability and wear.
MoMolybdenum	2.75%	Improves hardenability and toughness, boosts corrosion resistance, and helps the steel hold hardness under heat.
VVanadium	1.5%	Forms extremely hard vanadium carbides for superior edge retention, and refines the grain for a finer, tougher edge.
CCarbon	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.
WTungsten	1.25%	Forms hard carbides for wear resistance and edge stability, and keeps the steel hard even at elevated temperatures.
SiSilicon	0.3%	Strengthens the steel matrix and acts as a deoxidiser, improving hardness and resistance to oxidation.
MnManganese	0.3%	Aids hardenability and strength and acts as a deoxidiser in smelting. Too much can reduce toughness.
