 Njengensimbi engenasici kunye nobushushu obungangeni bushushu, umbhobho wentsimbi we-304 sesona sixhobo sisetyenziswa kakhulu kukutya, izixhobo zeekhemikhali ngokubanzi kunye neshishini lamandla e-athomu.

Ipayipi yensimbi ye-304 luhlobo lombhobho we-universal steel stainless, osetyenziswa ngokubanzi ukwenza izixhobo kunye neengxenye ezifuna ukusebenza kakuhle okubanzi (ukumelana nokubola kunye nokubumba).

Umbhobho wentsimbi we-304 unomhlwa ogqwesileyo kunye nokumelana nokugqwala kunye nokuchasana okuhle kwe-intergranular corrosion.

Isixhobo sombhobho wentsimbi engama-304 sinokuxhathisa okuqinileyo kwi-nitric acid engaphantsi kobushushu obubilayo kunye noxinzelelo≤65%.Ikwanayo nokumelana ne-corrosion efanelekileyo kwisisombululo se-alkali kunye neninzi ye-organic and inorganic acids.Uhlobo lwentsimbi ephezulu ye-alloy enokumelana nokubola emoyeni okanye kwimichiza ye-corrosion medium.Insimbi engagqwali luhlobo lwentsimbi enomgangatho omhle kunye nokumelana nokugqwala okuhle.Akuyomfuneko ukuba ingene kunyango lomphezulu olufana nokufakwa kombala, kodwa inika umdlalo opheleleyo kwiipropathi zendalo zomphezulu wentsimbi engatyiwayo.Isetyenziswa kwiinkalo ezininzi zentsimbi, ngokuqhelekileyo ibizwa ngokuba yintsimbi engenasici.Iintsimbi eziphezulu ze-alloy ezifana ne-13 chromium steel kunye ne-18-8 chromium-nickel steel zimele iipropati.

Njengensimbi engenasici kunye nobushushu obungangeni bushushu, umbhobho wentsimbi we-304 sesona sixhobo sisetyenziswa kakhulu kukutya, izixhobo zeekhemikhali ngokubanzi kunye neshishini lamandla e-athomu.
