STEELMAX Steel Story

PH13-8Mo 는, 석출 경화 (Precipitation Hardening)로
높은 강도를 가지는, 마르텐자이트 스테인레스입니다.

PH13-8Mo 는, 응력 부식 (stress corrosion)과
높은 강도 (high strength) — 1000~1500MPa ,

경도 (high hardness) — 30~45 HRc
좋은 연성과 인성 (ductility and toughness) 특징입니다.

PH13-8Mo 는, 또한 Molybdenum 합금으로, 다른 PH 합금인
15-5PH, 17-4PH 보다, 공식(pitting corrosion)에서 뛰어납니다.

※ Precipitation Hardening Steels (석출 경화 : 析出硬化)
Steels with the property of being hardened by a method wherein
a small amount of elements such as aluminium, copper, etc.
is added and compounds of those elements or the like are
precipitated by heat treatment.

알루미늄, 구리 등의 원소를 소량 첨가하고, 열처리에 의해
이들 원소 화합물을 석출 시켜 경화 하는 성질을 지니게 한 강.
