304 / 304L I-Stainless Steel Seamless Tubing
Isingeniso Somkhiqizo
Ama-alloys 304 (S30400) kanye nama-304L (S30403) ama-stainless steels ayizinhlobonhlobo ze-chromium engu-18% - 8% ye-nickel austenitic alloy, ingxubevange eyaziwa kakhulu nesetshenziswa kakhulu emndenini wensimbi engagqwali. 304/L insimbi engagqwali inezakhiwo ezinhle kakhulu zokwakha. Ukonakala kwayo kuvumela ukuthi yakheke kalula ukuvutha, ukugoba nokugoqa. Ukusebenza kahle kanye nokuqukethwe kwesibabule esincane kukhuthaza ukushisela okuhle kakhulu ezinhlelweni ezidinga lokho.
Amandla aphezulu, ukumelana nokugqwala okuhle kakhulu kanye nokuqukethwe kwekhabhoni encishisiwe kwenza i-Alloy 304 kanye ne-304L Stainless Steels lusebenziseke ezinhlelweni lapho kudingeka khona ukushisela. Okusetshenziswayo kufaka phakathi ukubunjwa kwezakhiwo kanye nokunquma, izingxenye ezishiselwe zamakhemikhali, izindwangu, iphepha, imishini yokucubungula imithi kanye nemboni yamakhemikhali.
Ezinye izinzuzo ukumelana kwayo ne-oxidation, ukwakheka okuhle kakhulu, ukulula kokwenziwa nokuhlanza, amandla amahle kakhulu esilinganisweni sesisindo kanye nokuqina okuhle emazingeni okushisa e-cryogenic Ezindaweni ezigqwala kakhulu, okuqukethwe okuphansi kohlobo lwe-304L kukhethwa ngenxa yokuzivikela okukhulu kokubola kwe-intergranular corrosion.
Uhlobo lwensimbi engu-304L inguqulo yekhabhoni ephansi kakhulu yensimbi engu-304ingxubevange. Okuqukethwe kwekhabhoni ephansi ku-304L kunciphisa imvula eyingozi noma eyingozi ye-carbide ngenxa yokushisela. Ngakho-ke, i-304L ingasetshenziswa "njengeshiselwe" endaweni enokugqwala okukhulu, futhi iqeda isidingo sokuhushula.
Leli banga linezakhiwo eziphansi kancane kunezinga le-304 elijwayelekile, kodwa lisasetshenziswa kabanzi ngenxa yokuguquguquka kwalo. Njengensimbi engagqwali ye-Type 304, ivamise ukusetshenziselwa ekwenzeni ubhiya nasekukhiqizeni iwayini, kodwa futhi ngezinjongo ezingaphezu kwemboni yokudla njengeziqukathi zamakhemikhali, izimayini, nezokwakha. Ilungele ukusetshenziswa ezingxenyeni zensimbi ezifana namantongomane namabhawodi avezwa emanzini anosawoti.
