Andika 304 na 304L Icyuma

Buri bwoko bwibyuma bidafite ingero byashyizwe mu ntera, mubisanzwe murukurikirane. Uru rukurikirane rushyira muburyo butandukanye bwa stainless kuva 200 kugeza 600, hamwe nibyiciro byinshi hagati. Buriwese uza ufite imitungo itandukanye kandi ugwa mumiryango harimo:

• austenitike:itari magnetique
• ferritic: rukuruzi
• duplex
• martensitike n'imvura ikomera:imbaraga nyinshi no kurwanya ruswa

Hano, turasobanura itandukaniro riri hagati yubwoko bubiri busanzwe buboneka ku isoko - 304 na 304L.

Ubwoko 304 nuburyo bukoreshwa cyane austenitisidafite umwandaibyuma. Azwi kandi nka “18/8 ″ ibyuma bitagira umwanda kubera ibiyigize, birimo 18%chromiumna 8%nikel. Andika 304 ibyuma bidafite ingese bifite uburyo bwiza bwo gusudira no gusudira kimwe bikomeyeruswakurwanya n'imbaraga.

Ubu bwoko bwicyuma butagira umwanda nabwo bufite uburyo bwiza bwo gukurura. Irashobora kubumbwa muburyo butandukanye kandi, bitandukanye nubwoko 302 butagira umwanda, irashobora gukoreshwa nta annealing, kuvura ubushyuhe byoroshya ibyuma. Ibikoreshwa muburyo bwa 304 ibyuma bitagira umwanda tubisanga mubiribwa. Nibyiza byo guteka, gutunganya amata, no gukora vino. Irakwiriye kandi imiyoboro, amasafuriya yimisemburo, amavatiri ya fermentation, hamwe nibigega byo kubikamo.

Ubwoko bwa 304 ibyuma bitagira umwanda biboneka no mubibindi, ibisate, inkono ya kawa, firigo, amashyiga, ibikoresho, nibindi bikoresho byo guteka. Irashobora kwihanganira ruswa ishobora guterwa n'imiti itandukanye iboneka mu mbuto, inyama, n'amata. Ibindi bice bikoreshwa birimo ubwubatsi, ibikoresho bya shimi, guhanahana ubushyuhe, ibikoresho byubucukuzi, hamwe nimbuto zo mu nyanja, bolts, hamwe na screw. Ubwoko 304 bukoreshwa kandi muri sisitemu yo gucukura no kuyungurura amazi no mu nganda zo gusiga amarangi.

Andika 304L ibyuma bidafite ingese ni verisiyo ya-karubone ntoya ya 304 ibyumaalloy. Ibiri munsi ya karubone muri 304L bigabanya imvura ya karbide idasobanutse cyangwa yangiza bitewe no gusudira. 304L irashobora rero gukoreshwa "nkuko isudira" ahantu habi cyane, kandi ikuraho ibikenewe.

Uru rutonde rufite imiterere yubukanishi munsi yicyiciro cya 304, ariko iracyakoreshwa cyane bitewe nuburyo bwinshi. Kimwe n'ubwoko bwa 304 ibyuma bitagira umwanda, bikoreshwa cyane mu guteka inzoga no gukora divayi, ariko kandi no mu bikorwa birenze inganda z’ibiribwa nko mu bikoresho bya shimi, ubucukuzi bw'amabuye y'agaciro, n'ubwubatsi. Nibyiza gukoreshwa mubice byicyuma nkibinyomoro na bolts bihura namazi yumunyu.
