Insimbi engagqwali 316,316L,316H

I-316 iyibanga elijwayelekile lokuthwala i-molybdenum, isibili ngokubaluleka kuya ku-304 phakathi kwezinsimbi ezingenasici ze-austenitic. I-molybdenum inika izakhiwo ezingcono kakhulu ezingu-316 ezimelana nokugqwala kunezingu-304, ikakhulukazi ukumelana nokugqwala nokugqwala kwemigodi ezindaweni ze-chloride. Inezici ezinhle kakhulu zokwakha kanye ne-welding. Ibhuleki kalula noma igoqeke yaba izingxenye ezihlukahlukene zokusetshenziswa ezimbonini, ezokwakha, nezokuthutha. I-316 nayo inezici zokushisela ezivelele. I-post-weld annealing ayidingeki lapho ushisela izingxenye ezincane.

316L, inguqulo yekhabhoni ephansi engu-316 futhi ivikelekile ekuzwaneni (imvula ye-carbide ye-grain boundary). Ngakho-ke isetshenziswa kakhulu ku-gauge esindayo izingxenye ezishiselwe (ngaphezu kuka-6mm).
I-316H, enokuqukethwe kwayo kwekhabhoni ephezulu iyasebenza emazingeni okushisa aphakeme, njengoba kwenza ibanga elingu-316Ti elizinzile.
Isakhiwo se-austenitic sinikeza lawa mabanga ukuqina okuhle kakhulu, ngisho naphansi kwamazinga okushisa e-cryogenic.

Amanye Amabanga Angenzeka

Ibanga	Kungani kungase kukhethwe esikhundleni sika-316?
316Ti	Kudingeka ukumelana kangcono namazinga okushisa acishe abe ngu-600-900 °C.
316N	Amandla aphezulu kune-standard 316.
317L	Ukumelana okuphakeme nama-chloride kuno-316L, kodwa ngokumelana okufanayo nokuqhekeka kokugqwala kwengcindezi.
904L	Ukumelana okuphezulu kakhulu nama-chloride emazingeni okushisa aphakeme, nokubukeka okuhle
