Uhlobo 630, olwaziwa kangcono ngokuthi 17-4, i-PH evame kakhulu engenasici. I-Type 630 iyinsimbi engagqwali ye-martensitic enikeza ukumelana nokugqwala okuphakeme. Ikazibuthe, ishiselwa kalula, futhi inezici ezinhle zokwakha, nakuba izolahlekelwa ukuqina okuthile emazingeni okushisa aphezulu. Yaziwa ngokumelana kwayo nokuqhekeka kwe-stress-corrosion, futhi isetshenziswa ezimbonini ezahlukahlukene nezinhlelo zokusebenza ezihlanganisa:
- Ama-valve namagiya
- Imishini yensimu kawoyela
- Ama-propeller shafts
- Imishini yepompo
- Ama-spindle ama-valve
- Izindiza kanye nezinjini zegesi
- Ama-reactors enuzi
- Izigayo zamaphepha
- Imishini yokucubungula amakhemikhali
Ukuze ithengiswe njenge-Type 630 Stainless Steel, kufanele iqukathe ukwakheka kwamakhemikhali okuhlukile okuhlanganisa:
- Cr 15-17.5%
- Kuze kube ngu-3-5%
- Mn 1%
- Si 1%
- P 0.040%
- S 0.03%
- Cu 3-5%
- Nb+Ta 0.15-0.45%
