Ụdị 630, nke a maara nke ọma dị ka 17-4, bụ igwe anaghị agba nchara PH. Ụdị 630 bụ igwe anaghị agba nchara martensitic nke na-enye nguzogide corrosion ka elu. Ọ bụ magnetik, na-agbado ngwa ngwa, ma nwee ezigbo njiri mara, n'agbanyeghị na ọ ga-efunahụ isi ike na okpomọkụ dị elu. A maara ya maka iguzogide nrụgide-corrosion cracking, a na-ejikwa ya n'ọtụtụ ụlọ ọrụ na ngwa dị iche iche gụnyere:
- Valves na gia
- Ngwá ọrụ ubi mmanụ
- Ogwe ihe eji eme ihe
- Osisi mgbapụta
- Mkpụrụ osisi Valve
- Ụgbọ elu na gas turbin
- Ihe nrụpụta nuklia
- Igwe igwe akwụkwọ
- Ngwa nhazi kemịkalụ
Ka e wee ree ya dị ka Ụdị 630 igwe anaghị agba nchara, ọ ga-enwerịrị ihe mejupụtara kemịkalụ pụrụ iche nke gụnyere:
- 15-17.5%
- Nke 3-5%
