316 kanye no-440 bangabasebukhosini be- insimbi engagqwali amabhola, Ngokumelana nokugqwala okuhle nokumelana nokugqwala okuqinile, futhi intengo iyenyuka ngenani. Ibhola le-Condar Steel elilandelayo lethula lokhu ngokuningiliziwe:
1.Amabhola wensimbi engagqwali angama-316—Ngemuva kuka-304, kuyibanga lensimbi lesibili elisetshenziswa kakhulu. Kusetshenziswa kakhulu embonini yokudla nemishini yokuhlinza. Ukwengezwa kwe-molybdenum kwenza kube isakhiwo esikhethekile sokumelana nokugqwala. Ngoba inokumelana okungcono ne-chloride corrosion kune-304, isetshenziswa futhi njenge "ship steel". I-SS316 ivame ukusetshenziselwa amadivayisi wokuvuselela amafutha enuzi, imishini yezokwelapha, imishini yokuntywila, njll.
2.Amabhola wensimbi engagqwali angama-440—Ithuluzi lensimbi lokusika eliphakeme elinokuqukethwe okungaphezulu kwekhabhoni. Ngemuva kokwelashwa okufanele kokushisa, amandla aphezulu wesivuno angatholakala. Ubulukhuni bungafinyelela ku-58HRC, okungenye yezinsimbi ezinzima kakhulu ezingenasici. Ukuhlanganisa izinzuzo zensimbi engagqwali nensimbi ethwele, ibizwa ngokuthi insimbi ekhethekile. Isibonelo esivame kakhulu sohlelo lokusebenza yi- “razor blades”. Kunamamodeli amathathu asetshenziswa kakhulu: i-440A, i-440B, i-440C, ne-440F (i-easy processing type).
