STEELMAX Steel Story

DIN EN 10028-3,규정은  Flat products made of steels for pressure purposes
Part 3 : Weldable fine grain steels, normalized 강재 규정입니다.

DIN EN 10028-3 강재는 모두  Normalized 열처리 된
압력용기용 용접 가능한 강재의 규정입니다.

P275NH, P275NL1, S355N, P355NH, P355NL1 — Non-alloy steels
P275NL2, P355LN2 — Non-alloy special steels

P460NH, P460NL, P460NL2 — Special steels 로,
DIN EN 10028-3,규정은, 합금 특수강과 탄소강이 같이 있습니다.

P×××N — room temperature quality steel
P×××NH — elevated temperature

P×××NL1 — low temperature
P×××NL2 — special low temperature 로 구분됩니다.

DIN EN 10028-3 는 지금 사용되고 있는 규정이고
이전 규격을 아래에 비교했습니다.

※ Fine grained steel (DIN-EN)
Steel with fine grain structure with an equivalent index of ferritic grain
size ≥ 6 determined in accordance with EN ISO 643

※Fine grained stee l(세립강 細粒鋼) : Steel with an austenitic grain size number is 5 or over…JIS

※ Fine grain steel
Steels which resist grain growth over a considerable temperature range,
when held at temperature for a reasonable length of time as is
customary in heat treatment of steel.

※ Steels for pressure vessels (압력용기용 강재 : 壓力容器用 鋼材)
Steel products manufactured pressure vessels and high pressure
equipment which require strength, weldability and principally
toughness at a ordinary temperature.
They are generally used for the principal portions of
pressure vessels.

압력용기 및 고압 설비용으로서 고온강도, 용접성 및 주로
상온에서의 인성을 중요시하여 제조 된 강재로
보통 압력용기의 주요 부분에 사용됩니다.
