Intsimbi engagqwaliyo engama-316 kunye nentsimbi engagqwaliyo engama-316L zombini ziyi-austenitic, zinamanqanaba afanayo e-chromium (16–18%), i-nickel (10–14%), kunye ne-molybdenum ephezulu (2–3%). Umahluko ophambili ngumxholo wekhabhoni we-316L ongaphantsi kwe-0.03%, xa kuthelekiswa nobuninzi be-0.08% kwi-316. I-carbon ephantsi inciphisa kakhulu imvula ye-chromium carbide ngexesha lemisebenzi yokuwelda.
316 vs 316L
*
I-Chromium carbide ingena kwimida yeenkozo xa amaqondo obushushu aphezulu esenzeka, ingakumbi phakathi kwe-450°C kunye ne-850°C, njengakwiindawo ezichaphazeleka bubushushu. Olu "luvo" lunciphisa i-chromium kwindawo kwaye lubangela ukuba i-intergranular corrosion ivele, ingakumbi kwiindawo ezinoburhalarhume be-chloride.
Ukusebenza, Ukumelana Nokugqwala, kunye Nokuxinana
Izinto eziNqanda ukuGqwala
Intsimbi engagqwaliyo engama-316 kunye nentsimbi engagqwaliyo engama-316L zimelana kakhulu nokugqwala komoya kunye neekhemikhali ngenxa yomxholo wazo we-molybdenum oyi-2–3%. Umahluko phakathi kwentsimbi engagqwali engama-316 kunye ne-316L ukwindlela ezisebenza ngayo emva kokwenziwa: umxholo wekhabhoni we-316L yi-≤0.03%, xa kuthelekiswa ne-≤0.08% kwi-316, nto leyo enciphisa kakhulu ukuna kwe-carbide kwimida yeenkozo emva kokuwelda. Le propati yenza intsimbi engagqwali engama-316L ibe yeyona ifanelekileyo kwiindawo ezinokuvezwa rhoqo kwiikloridi kunye nee-asidi, ezifana nezixhobo zaselwandle, iipayipi zenkqubo, kunye neetanki zeekhemikhali, ukugcina ukumelana nokugqwala komngxuma kunye nemingxunya, nakwiindawo zokuwelda.
Izinto eziqwalaselwayo malunga nokuxinana
Intsimbi engagqwaliyo ye-316L inika ukuwelda okuphezulu kwizakhiwo eziweldayo kumashishini okwakha, ezonyango, kunye neekhemikhali. Umxholo wayo ophantsi wekhabhoni (u003c0.03%) uthintela ukwakheka kwe-chromium carbide ngexesha lokuvezwa kobushushu, ukuthintela ukugqwala phakathi kwegranular kunye nokulahleka kokumelana nokugqwala kumalungu. Olu phawu luthintela ukuwelda okubuthathaka, ukuveliswa komhlwa, kunye nokugcinwa okubiza kakhulu, okuyimingcipheko xa intsimbi engagqwali ye-316 isetyenziswa gwenxa kwizicelo ezinobunzima obukhulu be-weld okanye ukujikeleza kobushushu okuphindaphindwayo. Umzekelo, izixhobo zokufakelwa kwezonyango, imithambo yoxinzelelo, kunye nezixhobo zokulungisa ukutya zisebenzisa i-316L kuphela ukuphepha ukusilela kwendawo ye-weld.
Imingeni yokwahlulahlula i-316 vs 316L
Imida yoHlolo oluBonakalayo
