Ndeupi musiyano uripo pakati pe304 ne316 simbi isina tsvina:

304 ndiro yesimbi isina tsvina inopesana nekuora ne sulfuric acid, phosphoric acid, formic acid, urea, nezvimwewo, uye inokodzera mvura yakawanda, kutonga gasi, waini, mukaka, CIP yekuchenesa mvura uye dzimwe nguva dzine kuderera kwakaderera kana kusasangana nezvinhu. 316L simbi yegiredhi yakawedzera molybdenum element pahwaro hwe304, iyo inogona zvakanyanya kuvandudza kupikisa kwayo kune intergranular corrosion uye oxide stress corrosion uye kuderedza tsika yekupisa kupisa panguva yewelding. Iyo inewo kurwisa kwakanaka kune chloride corrosion. Inowanzoshandiswa mumvura yakachena, mvura yakasvibiswa, mishonga, sosi, vhiniga uye zvimwe zviitiko zvine hutsanana hunodiwa uye yakasimba media corrosion properties. Mutengo we316L unosvika kaviri kune 304. Michina ye 304 iri nani pane iyo ye316L. Nekuda kwekushomeka kwekuora uye kushomeka kwe304 ne316, anoshandiswa zvakanyanya sesimbi isingadziviriri kupisa. Simba uye kuoma kwe304 uye 316 zvakafanana. Misiyano pakati pezviviri ndeyokuti kushorwa kwe 316 kuri nani kupfuura ye 304. Chinhu chinonyanya kukosha ndechokuti molybdenum metal inowedzerwa ku316, iyo inovandudza kupisa kupisa.

Zvimiro uye mashandisirwo anoshanda-304 ndiro yesimbi isina tsvina :

Simbi giredhi 321 maitiro-kushandisa mukurodza renji (450 ℃ ~ 850 ℃) -Boiler heat exchangers, pombi, majoini ekuwedzera uye mamwe mawelding, zvikamu / midziyo isingakwanise kupisa kupisa mushure mekusangana Kemikari yakagadzirwa: (yuniti: wt%)
