Alloys 304 (S30400) le 304L (S30403) litšepe tse sa hloekang ke mefuta e sa tšoaneng ea karolo ea 18 lekholong ea chromium - karolo ea 8 lekholong ea nickel austenitic alloy, motsoako o tloaelehileng le o sebelisoang hangata ka ho fetisisa lelapeng la tšepe e sa hloekang. 304/L tšepe e sa hloekang e na le thepa e ntle haholo ea ho etsa. Ho se sebetse hantle ha eona ho e lumella hore e thehoe habonolo bakeng sa ho tuka, ho kobeha le ho khoaela. Tšebeliso e ntle ea machina le sebabole se tlase se khothaletsa ts'ebeliso e ntle haholo lits'ebetsong tse e hlokang.
Matla a phahameng, khanyetso e ntle ea kutu le khabone e fokotsehileng li etsa hore Alloy 304 le 304L Stainless Steel e be molemo bakeng sa lits'ebetso moo ho hlokahalang ho cheselletsa. Ts'ebeliso e kenyelletsa meaho ea meralo le meaho, likarolo tse cheselitsoeng tsa lik'hemik'hale, masela, pampiri, lisebelisoa tsa ho sebetsa tsa indasteri ea meriana le ea lik'hemik'hale.
Melemo e meng ke ho hanyetsa ha oxidation, sebopeho se setle haholo, bonolo ba ho etsoa le ho hloekisa, matla a babatsehang a boima ba 'mele le ho tiea ho hotle ha mocheso oa cryogenic Bakeng sa libaka tse senyang haholo, mefuta e tlaase ea Mofuta oa 304L e khethoa ka lebaka la ho itšireletsa ho matla ho feta intergranular corrosion.
Mofuta oa 304L tšepe e sa hloekang ke mofuta oa khabone e tlase haholo ea tšepe ea 304motsoako. Likahare tse tlase tsa khabone ho 304L li fokotsa pula e kotsi kapa e kotsi ea carbide ka lebaka la ho cheselletsa. Ka hona, 304L e ka sebelisoa "joalo ka welded" libakeng tse matla tsa kutu, 'me e felisa tlhoko ea ho anneal.
Sehlopha sena se na le thepa e tlase hanyane ho feta ea maemo a tloaelehileng a 304, empa e ntse e sebelisoa haholo ka lebaka la ho feto-fetoha ha eona. Joalo ka tšepe ea mofuta oa 304, hangata e sebelisoa ha ho riteloa biri le ha ho etsoa veine, empa hape e sebelisetsoa merero e fetang indasteri ea lijo joalo ka lijaneng tsa lik'hemik'hale, merafong le kahong. E loketse ho sebelisoa likarolong tsa tšepe tse kang linate le liboutu tse pepesehileng metsing a letsoai.
