430F ba wonn pur (ASTM A276; GB 10Cr17Mose) se yon gratis - Variant machining nan 430, ak pwopriyete pwepare pou machining presizyon:
Fòs rupture: 450-600 MPa (menm jan ak 430), men ak te ajoute souf (0.15-0.30%) amelyore rupture chip pandan koupe.
Dite: 180-220 HB (yon ti kras pi wo pase 430 la 170-200 Hb) akòz enklizyon souf, men yo toujou machinabl ak zouti estanda.
Rezistans korozyon: yon ti kras pi ba pase 430 (akòz souf), men ase pou anviwònman sèk tankou aparèy nan kay la.
Machinability: 30-40% pi bon pase 430, diminye mete zouti ak tan machining pou pati konplèks.
430F yo itilize nan konpozan aparèy kwizin (egzanp, lam blenndè), otomobil Fastener taye, ak tij valv - aplikasyon kote machinabilite se priyorite sou rezistans korozyon ekstrèm. Li se pi bon mache pase austenitik gratis - klas machining tankou 303, fè li yon pri - Chwa efikas pou ki pa - pati kritik.
