ʻO Type 630, ʻoi aku ka maikaʻi o ka 17-4, ʻo ia ka PH maʻamau maʻamau. ʻO ke ʻano 630 kahi kila stainless martensitic e hāʻawi ana i ke kūpaʻa corrosion maikaʻi. He magnetic, hiki ke wiliwili ʻia, a he mau hiʻohiʻona hana maikaʻi, ʻoiai e nalowale ana ka paʻakikī i nā wela kiʻekiʻe. Ua ʻike ʻia no kona kūpaʻa ʻana i ke koʻikoʻi-corrosion cracking, a hoʻohana ʻia i nā ʻano hana like ʻole a me nā noi e like me:
- ʻO nā kiwi a me nā mea hana
- Mea lako kahua aila
- ʻO nā lāʻau propeller
- Pum shafts
- ʻO nā wili pahu
- Nā mokulele mokulele a me ke kinoea
- Nukelea reactors
- Hale wili pepa
- Mea hana kemika
No ke kūʻai ʻia ʻana e like me Type 630 Stainless Steel, pono e loaʻa i kahi ʻano kemika kūʻokoʻa e komo pū ana:
- Cr 15-17.5%
- Ni 3-5%
- Mn 1%
- ʻO 1%
- P 0.040%
- S 0.03%
- Cu 3-5%
- Nb+Ta 0.15-0.45%
