Uhlobo lwe-630, olubizwa ngokuba yi-17-4, yeyona PH ixhaphakileyo. Uhlobo lwe-630 yintsimbi ye-martensitic engenasici enika ukuxhathisa okuphezulu kwe-corrosion. Inemagnethi, iwelded ngokulula, kwaye ineempawu ezilungileyo zokuyila, nangona iya kuphulukana nokuqina okuthile kumaqondo obushushu aphezulu. Iyaziwa ngokuchasana noxinzelelo lwe-corrosion cracking, kwaye isetyenziswa kwiintlobo ngeentlobo zamashishini kunye nokusetyenziswa okubandakanya:
- Iivalvu kunye nezixhobo
- Izixhobo zentsimi yeoli
- Iintsimbi zepropeller
- Iimpompo zeempompo
- Iintambo zevalvu
- Iinqwelomoya kunye nee turbines zegesi
- Izixhobo zenyukliya
- Amaphepha okusila
- Izixhobo zokulungisa imichiza
Ukuze ithengiswe njenge-Type 630 Stainless Steel, kufuneka iqulathe ukwakheka kweekhemikhali ezizodwa ezibandakanya:
- Cr 15-17.5%
- Ni 3-5%
- Mn 1%
- Si 1%
- P 0.040%
- S 0.03%
- Cu 3-5%
- Nb+Ta 0.15-0.45%
