Ama-alloys 304 (S30400) kanye ne-304L (S30403) ayinsimbi engagqwali ahlukahluka kweyi-alloy ye-austenitic ene-chromium engamaphesenti angu-18 – ne-nickel engamaphesenti angu-8, okuyi-alloy ejwayeleke kakhulu futhi esetshenziswa kakhulu emndenini wensimbi engagqwali. I-304/L stainless steel inezimfanelo ezinhle kakhulu zokukhiqiza. Ukuthambeka kwayo kuyenza ikwazi ukubunjwa kalula ukuze igobe, igobe futhi isongwe. Ukusebenza kahle emishinini kanye nezinga eliphansi le-sulfur kukhuthaza ukushiswa okuhle kakhulu ezinhlelweni ezikudingayo.

Amandla aphezulu, ukumelana nokugqwala okuhle kanye nokuqukethwe kwekhabhoni okuncishisiwe kwenza i-Alloy 304 ne-304L Stainless Steels zibe usizo ezinhlelweni lapho ukushisela kudingeka khona. Ukusetshenziswa kufaka phakathi ukubunjwa kwezakhiwo nokuhlobisa, izingxenye ezishiselwe zemishini yokucubungula yamakhemikhali, eyindwangu, yephepha, yemithi kanye nezimboni zamakhemikhali.

Okunye okuhle ukumelana nokugqwala nge-oxidation, ukubunjwa kahle kakhulu, ukwenza kalula nokuhlanzeka, ukumelana namandla okuhle uma kuqhathaniswa nesisindo kanye nokuqina okuhle emazingeni okushisa aphansi kakhulu. Ezindaweni ezigqwala kakhulu, uhlobo 304L olunokuqukethwe okuphansi lukhethwa ngenxa yokungagqwali kahle phakathi kwezinhlamvu zensimbi.

Insimbi engagqwali yohlobo 304L inguqulo enekhabhoni ephansi kakhulu yensimbi engu-304ingxubevange. Okuqukethwe kwekhabhoni ephansi ku-304L kunciphisa ukuncipha kwe-carbide eyingozi noma elimazayo ngenxa yokushisela. Ngakho-ke, i-304L ingasetshenziswa "njengoba ishiselwe" ezindaweni ezinokugqwala okubi, futhi iqeda isidingo sokufudunyezwa.

Leli banga linamandla aphansi kancane kunezinga elijwayelekile lika-304, kodwa lisasetshenziswa kabanzi ngenxa yokuthi lisebenza ezimweni eziningi. Njenge-Type 304 stainless steel, livame ukusetshenziswa ekwenzeni ubhiya newayini, kodwa futhi nangezinye izinjongo ezingaphandle komkhakha wokudla njengezitsha zamakhemikhali, ezimayini, nasekwakheni. Lifanelekele ukusetshenziswa ezingxenyeni zensimbi ezinjengamantongomane nezikulufo ezivezwa emanzini anosawoti.
