STEELMAX Steel Story

Alloy P900, A289 는, 전자 산업용에 사용되는
Chromium, Manganese, 1 : 1 합금입니다.

Chromium 17.5~20.0%,
Manganese 17.5~20.0% 합금입니다.

ASTM A289 Standard Specification for Alloy Steel forgings for
Non-magnetic Retaining Rings for Generators 규정입니다.

Alloy P900, ASTM A289 은,
DIN-EN 1.3816, X8CrMnN18-18 과 대응 가능합니다.

※ 비자성강 (Non-magnetic steels : 非磁性鋼)
탄소, 망간, 니켈, 크롬, 질소 등을 주된 합금 성분으로 하고, 오스테나이트계 조직을
나타내는 비자성의 합금강. 조직적으로는 고망간강계, 고니켈계 및 이들의
중간형의 3종으로 대별 됩니다.
비자성강은 발전기, 계전기 등의 전자기 부재, 핵융합 설비 등으로 사용됩니다.

Non-magnetic alloy steels with austenitic structure, in which carbon,
manganese, nickel, chromium, nitrogen, etc. as main alloy elements
are contained.
They are classified into 3 types, which are high manganese series,
high nickel series and intermediate type, according to composition.
For example, they are used for electromagnetic components of
generators, relays, etc., and components of nuclear fusion reactors
and linear motor cars.
