Abantu abaningi kulula ukudida ipayipi lensimbi engu-316 kanye nepayipi lensimbi engu-316L, becabanga ukuthi bawuhlobo olufanayo lwepayipi lensimbi, kodwa empeleni akunjalo.
Umehluko othize phakathi kuka-316 no-316L wezinsimbi ezingenasici umi kanje:
1. Ukwakheka kwamakhemikhali
Okuqukethwe kwekhabhoni yensimbi engagqwali engu-316L kungaphansi kwalokho kwensimbi engagqwali engu-316.Kungashiwo ukuthi "316L" iyi-ultra-low carbon 316 insimbi engagqwali.Insimbi engagqwali engu-316L inokuqukethwe okuphezulu kwe-molybdenum kuno-316.
2. Ukumelana nokugqwala
Insimbi engagqwali engu-316L inokumelana nokugqwala okungcono.
3. Amandla
I-316 inezakhiwo eziqinile zemishini.Amandla aqinile wepayipi lensimbi engagqwali angu-316 aphakeme kunalawo wepayipi lensimbi engu-316L.Amandla ensimbi engagqwali angu-316 adingeka ukuthi abe mkhulu kuno-520MPa, kuyilapho lawo ensimbi engu-316L edingeka kuphela ukuze abe mkhulu kuno-480MPa.Lokhu kungenxa yokuthi i-carbon (C) iyisici esiqinile esakha i-austenitic, engathuthukisa kakhulu amandla ensimbi.
4. Ukumelana nokushisa okuphezulu
I-316L insimbi engagqwali ingasetshenziswa ngokuqhubekayo ekushiseni okuphezulu, kuyilapho i-316 ingakwazi.Ebangeni lama-800 ~ 1575 degrees, kungcono ukungaqhubeki ngokuqhubekayo ku-316 insimbi engagqwali.I-carbide precipitation resistance ye-316L yensimbi engagqwali ingcono kune-316 yensimbi engagqwali, futhi ingasetshenziswa ngokuqhubekayo ebangeni lama-800 ~ 1575 degrees.
5. Ukushisela
I-316 insimbi engagqwali inokushisela okuhle, okungashiselwa ngezindlela ezijwayelekile zokushisela.Ingxenye yokushisela yensimbi engagqwali engu-316 idinga ukushiselwa kwe-post welding ukuze kuthuthukiswe ukumelana nokugqwala.Nokho, uma 316L insimbi engagqwali kusetshenziswa, post weld annealing akudingekile.
