I-AISI 316/316L ENGAGAMA

Umehluko Phakathi kuka-316 no-316L Insimbi Engagqwali

Umehluko phakathi kuka-316 no-316L wensimbi engagqwali ukuthi 316L ine-.03 max carbon futhi ilungele ukushisela kanti i-316 inezinga eliphakathi lebanga le-carbon.316 kanye no-316L ama-alloys e-austenitic, okusho ukuthi le mikhiqizo yensimbi engagqwali ithola ukumelana nokugqwala ngokusetshenziswa. yesisombululo esiqinile esingenazibuthe se-ferric carbide noma ikhabhoni esensimbi ekukhiqizeni.

Ngaphezu kwe-chromium ne-nickel, lawa ma-alloys aqukethe i-molybdenum, ewenza amelane nokugqwala. Ukumelana nokugqwala okukhulu nakakhulu kulethwa ngu-317L, lapho okuqukethwe kwe-molybdenum kukhuphuka kuya ku-3 kuya ku-4% kusukela ku-2 kuya ku-3% etholakala ku-316 naku-316L.

Izakhiwo kanye nokusetshenziswa kwe-316 kanye ne-316L yensimbi engagqwali

Lawa ma-alloys aziwa ngezakhiwo zawo ezinhle kakhulu zokushisela, ezihlanganiswe yizinqubo zombili zokuhlanganisa kanye nokumelana. Inguqulo ye-316L yekhabhoni ephansi ikhethwa ezindaweni ezigqwalile. Kubalulekile ukwenza isiqiniseko sokuthi ithusi ne-zinc akubi ukungcola endaweni yokushisela, njengoba lokhu kungadala ukuqhekeka.Kujwayelekile ukwenza u-316 no-316L abe yizimo eziningi ezahlukene. Angase akheke ezintweni ezifana nensimbi ye-carbon, futhi ambozwe kalula futhi abhoboze. Ukonakala okuhle kakhulu kusho ukuthi basebenza kahle ekudwebeni okujulile, ukuphotha, ukwelula nokugoba.

Izakhiwo zemishini

Phakathi kwazo zonke izinsimbi, i-austenitic insimbi engagqwali inephuzu eliphansi lesivuno.Ngakho-ke, uma kucatshangelwa izakhiwo zemishini, insimbi engagqwali ye-austenitic ayiyona into engcono kakhulu yesiqu, ngoba ukuqinisekisa amandla athile, ububanzi besiqu buzokhula. Iphuzu lesivuno alikwazi ukuthuthukiswa ngokwelashwa kokushisa, kodwa lingathuthukiswa ngokwakhiwa okubandayo.
