Ibigize imiti 304 ibyuma bitagira umwanda C ≤ 0.08 Si ≤ 1.00 Mn ≤ 2.00 P ≤ 0.05 S ≤ 0.03 Cr 18.00-20.00 Ni (nikel) 8.00 ~ 10.50 -;
Ibigize imiti ya 304L ibyuma bidafite ingese ni% C: ≤ 0.03, Si: ≤ 1.0, Mn: ≤ 2.0, Cr: 17.0 ～ 19.0, Ni: 8.0 ～ 11.0, S: ≤ 0.03, P: ≤ 0.035.
Birashobora kugaragara ko ibice byingenzi bigize 304 ibyuma bitagira umwanda na 304L ibyuma bitagira umuyonga ni chromium 18% (Cr) na nikel 8% (Ni);Itandukaniro nyamukuru hagati yabo nuko 304L ibyuma bidafite ingese nicyuma gike-karubone 304.Muri rusange, kurwanya ruswa ya 304L ibyuma bitagira umwanda bisa na 304 ibyuma bitagira umwanda, ariko nyuma yo gusudira cyangwa kugabanya imihangayiko, imbibi z’imbibi zirwanya 304L ibyuma bitagira umwanda ni byiza
Kubijyanye nigiciro, 304L ibyuma bitagira umuyonga birenze 304 ibyuma bitagira umwanda, naho 304L ibyuma bitagira umuyonga ni ibyuma bya karuboni nkeya, cyane cyane bikoreshwa muburyo bwo gusudira.Iyo gusudira, ibyuma 304L bidafite ingese birashobora kugabanya neza kwangirika.
Ukurikije uburinganire bukomeye, 304 ibyuma bidafite ingese biruta 304L ibyuma bitagira umwanda, kubera ko ibirimo karubone bigira ingaruka ku buryo butaziguye ubukana bwibyuma.Mubyongeyeho, hari 304H ibyuma bitagira umwanda.H yerekana ibintu byinshi bya karubone.
Kubyerekeranye no kubishyira mu bikorwa, 304: 0Cr18Ni9, nkicyuma gifite uburyo bwinshi bwo gukoresha, gifite imbaraga zo kurwanya ruswa, kurwanya ubushyuhe, imbaraga zubushyuhe buke hamwe nubukanishi;Kashe, kunama nibindi bikorwa bishyushye nibyiza, kandi ntaburyo bwo kuvura ubushyuhe bukomeye (butari magnetique, koresha ubushyuhe bwa - 196 ℃ ~ 800 ℃).Ibikoresho byo murugo (Icyiciro cya 1 nicya 2 ibikoresho byo kumeza, akabati, imiyoboro yo murugo, ubushyuhe bwamazi, amashyiga, ubwogero), ibice byimodoka (guhanagura ibirahuri byumuyaga, muffler, ibicuruzwa bibumbabumbwe), ibikoresho byubuvuzi, ibikoresho byubaka, imiti, inganda zibiribwa, ubuhinzi, nibice byubwato .
304L: 00Cr19Ni10 nicyuma C 304 gito.Muri rusange, kurwanya kwangirika kwayo bisa n’ibyuma 304, ariko nyuma yo gusudira cyangwa kugabanya imihangayiko, kurwanya imbibi z’imbibi ni byiza;Irashobora kandi gukomeza kurwanya ruswa idashobora kuvura ubushyuhe, kandi ubushyuhe bwa serivisi ni - 196 ℃ ～ 800 ℃.
Ikoreshwa kumashini yo hanze mubikorwa bya chimique, amakara na peteroli hamwe nibisabwa cyane mukurwanya imbibi zangirika kwangirika, ibice birwanya ubushyuhe bwibikoresho byubwubatsi nibice bya zeru bifite ikibazo cyo kuvura ubushyuhe
