Phakathi kweentlobo ezahlukeneyo zentsimbi engenasibala, amaBanga 304, 304L, kunye ne-304h zihlala zisetyenziswa. Ngelixa banokujonga okufanayo, ibakala ngalinye linepropathi yayo eyahlukileyo kunye nezicelo.
IbangaIntsimbi engama-304zezona zisetyenziswa kakhulu kwaye ziguquguqukayo kwizinto ezingama-300 ze-300. Iqulethe i-18 ukuya kwi-20% ye-chromium kunye ne-8-10.5% nickel, kunye ne-carbon encinci, in Manganese, naseSilicon. Eli nqanaba lingamelana nokunganyangeki kakuhle kunye nokuqina okuhle. Ihlala isetyenziswa kwizicelo ezinje ngesixhobo sekhitshi, ukulungiswa kokutya, kunye nokuhonjiswa kwendalo.
I-304l yentsimbi engenasitayileNgaba ngumbhobho we-carbon ye-carbon yentsimbi yeBanga lama-304, kunye nomxholo wekhabhoni ephezulu ye-0.03%. Lo mxholo wekhabhoni ophantsi unceda ukunciphisa ukuqhuma kwe-carbide ngexesha le-welding, eyenza ilungele izicelo ze-welding. Umxholo wekhabhoni esezantsi uyawunciphisa umngcipheko wemvakalelo, oko kukwenziwa kwe-chromium carbide kwimida yokudla okuziinkozo, enokukhokelela kwi-insosion engaphakathi. I-304l ihlala isetyenziswa kwizicelo ze-wels, kunye neendawo apho umngcipheko wokolula yinkxalabo, njengokuqhubela phambili kwemichiza kunye nezixhobo zamayeza.
304h intsimbi engenasitayileNgaba yinguqulelo yekharbon ephezulu yeBanga lama-304, ngomxholo wekhabhoni osusela kwi-0.04-0.10%. Umxholo wekhabhoni ephezulu ubonelela ngamaqondo obushushu angcono kunye nokunganyangeki. Oku kwenza ukuba i-304H ilungele ukuba amaqondo obushushu amaqondo obushushu, anjengeenqanawa zoxinzelelo, abatshintshisa-bushushu, kunye nabaphathi bemizi-mveliso. Nangona kunjalo, umxholo wekhabhoni ephezulu wenza i-304h engachaphazelekanga kwimvakalelo yokuziva unesifo sengqondo kunye nosulelo longenelelo, ngakumbi kwizicelo ze-wels.
Kwisishwankathelo, umahluko omkhulu phakathi kwala manqanaba ngumxholo wekhabhoni wawo kunye nefuthe kwizicelo ze-welding kunye nezicelo zeqondo lobushushu. Ibanga lama-304 lelona njongo isetyenziswa kakhulu kunye nenjongo ngokubanzi, ngelixa i-304l yoluhlobo olukhethiweyo kwizicelo ze-welding kunye neemeko apho ingcolo iyo inkxalabo. 304h inomxholo wekhabhoni ephezulu kwaye ilungele ukusetyenziswa kobushushu obuphezulu, kodwa ukusingelwa kwayo kwimvakalelo yokuziva unesifo semvakalelo kunye nokungaxhaphaza phakathi komntu kufuna ukuqwalaselwa ngononophelo. Xa ukhetha phakathi kwamabakala, kubalulekile ukuqwalasela iimfuno ezithile zesicelo, kubandakanya nendawo yokusebenza, ubushushu, kunye neemfuno ze-welding.
