Intangiriro

Icyiciro cya 304 ni cyo cyuma gisanzwe cya "stainless 18/8″; ni cyo cyuma gikoreshwa cyane kandi gikoreshwa cyane, kiboneka mu bicuruzwa bitandukanye, imiterere n'irangi kurusha ibindi byose. Gifite imiterere myiza yo gukora no gusudira. Imiterere iboneye ya Grade 304 ituma ikururwa cyane nta gukururwa hagati, byatumye iki cyiciro kiba ingenzi mu gukora ibice bya "stainless" nk'amasafuriya, ibikoresho bito n'amasafuriya. Kuri izi porogaramu, bikunze gukoreshwa ubwoko bwihariye bwa "304DDQ" (Deep Drawing Quality). Icyiciro cya 304 cyoroshye gufunga cyangwa kuzingira mu bice bitandukanye byo gukoreshwa mu nganda, mu bwubatsi, no mu gutwara abantu. Icyiciro cya 304 gifite imiterere idasanzwe yo gusudira. Gusudira nyuma yo gusudira ntibikenewe iyo usudira ibice bito.

Ingano ya 304L, verisiyo ya 304 ifite karubone nkeya, ntisaba gukurura nyuma yo gusudira, bityo ikoreshwa cyane mu bice by'icyuma biremereye (birenga mm 6). Ingano ya 304H ifite karubone nyinshi ikoreshwa mu bushyuhe bwinshi. Imiterere ya austenitic inaha izi ngeri gukomera cyane, ndetse no mu bushyuhe bukabije.

Imiterere y'ingenzi

Iyi miterere yagenwe ku gicuruzwa gipfundikiye (isahani, urupapuro n'uruziga) muri ASTM A240/A240M. Imiterere isa ariko ntabwo ari ngombwa ko isa yagenwe ku bindi bicuruzwa nk'umuyoboro n'inkingi mu buryo bwabyo.

Imiterere

Ingano zisanzwe z'ibikubiye mu byuma bitagira umugese byo mu rwego rwa 304 zigaragazwa mu mbonerahamwe ya 1.

Imiterere ya mekanike

Imiterere isanzwe ya mekanike ku byuma bita steel byo mu rwego rwa 304 igaragazwa mu mbonerahamwe ya 2.

Ubudahangarwa bw'inkongi

Ni nziza cyane mu bidukikije bitandukanye kandi bikoresha uburyo bwinshi bwo kwangiza. Ishobora kwangiza imyobo n'imyanya mu bidukikije bishyushye bya chloride, kandi ikagira ingaruka ku kwangiza hejuru ya dogere selisiyusi 60. Ifatwa nk'irwanya amazi meza hamwe na dogere selisiyusi zigera kuri 200mg/L ku bushyuhe bw'ikirere, ikagabanukaho dogere selisiyusi 150mg/L kuri dogere selisiyusi 60.

Ubudahangarwa bw'ubushyuhe

Ubudahangarwa bwiza bwo kugabanya ubushyuhe mu gihe bugera kuri 870°C no mu gihe bugera kuri 925°C. Ntabwo byemewe gukoresha 304 mu gihe gikurikiraho mu gihe cyo kurwanya ingese mu mazi. 304L yo mu rwego rwo hejuru irwanya cyane imvura ya karuboni kandi ishobora gushyushywa mu gihe cy’ubushyuhe bwavuzwe haruguru.

Ingano ya 304H ifite imbaraga nyinshi mu bushyuhe buri hejuru, bityo ikunze gukoreshwa mu bikorwa by’ubwubatsi n’ibijyanye n’umuvuduko ku bushyuhe buri hejuru ya 500°C no kugeza kuri 800°C. 304H izarushaho kuba ingenzi mu bushyuhe buri hagati ya 425-860°C; iki si ikibazo ku bushyuhe bwinshi, ariko kizagabanya ubudahangarwa bw’amazi mu kurwanya ingese.

Uburyo bwo kuvura ubushyuhe

Uburyo bwo Gutunganya Umuti (Annealing) – Shyushya kugeza kuri 1010-1120°C kandi ukonje vuba. Ubu bwoko ntibushobora gukomera hakoreshejwe uburyo bwo gushyushya.

Gusudira

Uburyo bwo gusudira bwiza cyane hakoreshejwe uburyo bwose busanzwe bwo guhuza ibyuma, haba hamwe n'ibidafite ibyuma. AS 1554.6 ibanza kwemerera gusudira 304 hamwe n'icyiciro cya 308 na 304L hamwe n'inkoni cyangwa electrodes za 308L (kandi zifite silicon nyinshi). Ibice biremereye byo gusudira muri Grade 304 bishobora gusaba gusudira nyuma yo gusudira kugira ngo birwanye ingese cyane. Ibi ntibisabwa kuri Grade 304L. Grade 321 ishobora kandi gukoreshwa nk'ubundi buryo bwo gusimbura 304 niba gusudira igice kinini bikenewe kandi ubushyuhe nyuma yo gusudira bidashoboka.

Porogaramu

Porogaramu zisanzwe zirimo:

Ibikoresho byo gutunganya ibiribwa, cyane cyane mu gukora inzoga, gutunganya amata no gukora divayi.

Intebe zo mu gikoni, sinki, imiyoboro, ibikoresho n'ibikoresho

Imiterere y'inyubako, inkingi z'amabuye n'imitako

Ibikoresho bya shimi, harimo n'ibyo gutwara

Imashini zihindura ubushyuhe

Ibikoresho biboshye cyangwa bisutsweho ubucukuzi bw'amabuye y'agaciro, ubucukuzi bw'amabuye y'agaciro n'amazi

Ibikoresho byo gufatanya bifite insinga
