Ibyuma bitagira umwanda 304,304L, 304H

Ibyuma bitagira umwanda 304 hamwe nicyuma 304L bizwi kandi nka 1.4301 na 1.4307. 304 nicyuma kinini kandi gikoreshwa cyane ibyuma bidafite ingese. Biracyavuzwe rimwe na rimwe n'izina ryayo rya kera 18 / 8 rikomoka ku mazina ya 304 ari 18% chromium na 8% nikel. 304 ibyuma bidafite ingese nicyiciro cya austenitis gishobora gushushanywa cyane. Uyu mutungo watumye 304 iba urwego rwiganje rukoreshwa mubisabwa nka sink na sosi.

304L ni verisiyo ya karubone yo hasi ya 304. Ikoreshwa mubice biremereye byo gupima neza.

304H, ibintu byinshi birimo karubone, iraboneka no gukoreshwa mubushyuhe bwinshi.

Ibishoboka Ibindi Byiciro

Icyiciro	Impamvu ishobora guhitamo aho kuba 304
301L	Urwego rwohejuru rukomeye urwego rusabwa kurwego runaka rwakozwe cyangwa kurambura ibice.
302HQ	Igipimo cyo hasi cyumurimo kirakenewe mugukonjesha gukonje kwimigozi, bolts na rivets.
303	Imashini yo hejuru irakenewe, hamwe no kurwanya ruswa yo hasi, guhinduka no gusudira biremewe.
316	Birakenewe cyane guhangana na pitingi na crevice ruswa, mubidukikije bya chloride
321	Kurwanya neza ubushyuhe bwa dogere 600-900 ° C birakenewe… 321 ifite imbaraga zishyushye cyane.
3CR12	Igiciro gito kirakenewe, kandi kugabanuka kwangirika kwangirika no kuvamo amabara biremewe.
430	Igiciro gito kirakenewe, kandi kugabanuka kwangirika kwangirika nibiranga ibihimbano biremewe.
