316L Tšepe e se nang Mokelikeli

Sebopeho, Litšobotsi le Lisebelisoa

Ho utloisisa tšepe e sa hloekang ea 316L, motho o tlameha ho qala ho utloisisa tšepe e sa hloekang ea 316.

316 ke austenitic chromium-nickel tšepe e sa jeleng paate e nang le molybdenum e pakeng tsa tse peli le 3%.Likahare tsa molybdenum li ntlafatsa ho hanyetsa kutu, li eketsa khanyetso ea ho kenella ka har'a litharollo tsa ion tsa chloride, 'me li ntlafatsa matla mochesong o phahameng.

316L Stainless Steel ke eng?

316L ke tekanyo e tlaase ea carbon ea 316. Sehlopha sena ha se sireletsehe ho sensitization (grain boundary carbide precipitation).E sebelisoa khafetsa ka likarolo tse boima tse cheselitsoeng (hoo e ka bang ho feta 6mm).Ha ho na phapang e hlokomelehang ea theko pakeng tsa 316 le 316L tšepe e sa hloekang.

316L tšepe e sa hloekang e fana ka likhahla tse phahameng, khatello ea maikutlo ho phatloha le matla a tsitsitseng mochesong o phahameng ho feta chromium-nickel austenitic stainless steels.

Likhetho tsa Alloy

Lentsoe "L" le bolela feela "khabone e nyane."316L e na le khabone e nyane ho feta 316.

Litlhaloso tse tloaelehileng ke L, F, N, le H. Sebopeho sa austenitic sa lihlopha tsena se fana ka matla a babatsehang, esita le mocheso oa cryogenic.

304 vs. 316 Stainless Steel

Ho fapana le tšepe ea 304 - tšepe e sa hloekang e tsebahalang ka ho fetesisa - 316 e na le khanyetso e ntlafalitsoeng ea kutu ho tsoa ho chloride le li-acid tse ling.Sena se etsa hore ho be molemo bakeng sa lits'ebetso tsa kantle tse tikolohong ea leoatle kapa lits'ebetso tse ka bang kotsing ea ho pepesetsoa chloride.

Ka bobeli 316 le 316L li bonts'a khanyetso e ntle ea kutu le matla ho mocheso o phahameng ho feta molekane oa tsona oa 304 - haholo-holo ha ho tluoa tabeng ea ho senya le ho bola ha mobu libakeng tsa chloride.

316 vs. 316L Stainless Steel

316 tšepe e sa hloekang e na le khabone e ngata ho feta 316L.316 tšepe e na le boemo bo bohareng ba khabone 'me e na le pakeng tsa 2% le 3% molybdenum, e fanang ka ho hanyetsa ho bola, likarolo tse nang le asiti le mocheso o phahameng.

E le hore u tšoanelehe ho ba 316L tšepe e sa hloekang, palo ea carbon e tlameha ho ba tlaase - ka ho khetheha, e ke ke ea feta 0.03%.Maemo a tlase a khabone a etsa hore 316L e be bonolo ho feta 316.

Leha ho na le phapang lipakeng tsa khabone, 316L e ts'oana haholo le 316 hoo e batlang e le ka litsela tsohle.

Litšepe ka bobeli li bonolo haholo, li na le thuso ha ho etsoa libopeho tse hlokahalang bakeng sa morero ofe kapa ofe ntle le ho pshatleha kapa ho petsoha, 'me li na le khanyetso e phahameng ea ho bola le matla a phahameng a tsitsipano.

Litšenyehelo lipakeng tsa mefuta ena e 'meli lia bapisoa.Ka bobeli li fana ka nako e telele, ho hanyetsa kutu, 'me ke likhetho tse ntle lits'ebetsong tse nang le khatello e phahameng ea maikutlo.

316L e nkoa e loketse morero o hlokang tjheseletso e ngata.316, ka lehlakoreng le leng, ha e khone ho bola ka har'a weld (weld decay) ho feta 316L.Ho boletse joalo, annealing 316 ke ts'ebetso ea ho hanela ho bola ha weld.

316L e ntle bakeng sa ts'ebeliso ea mocheso o phahameng, e nang le kutu e phahameng, e amahanngoang le botumo ba eona mererong ea kaho le ea leoatleng.

Ka bobeli 316 le 316L li na le ts'ebetso e ntle haholo, li sebetsa hantle ho kobeheng, ho otlolla, ho taka ka botebo le ho ohla.Leha ho le joalo, 316 ke tšepe e thata ho feta e nang le matla a holimo le ductility ha e bapisoa le 316L.
