 Njengensimbi engagqwali futhi ekwazi ukumelana nokushisa, ipayipi lensimbi elingu-304 liwumshini osetshenziswa kakhulu ukudla, okokusebenza kwamakhemikhali jikelele kanye nemboni yamandla e-athomu.

Ipayipi lensimbi engu-304 iwuhlobo lwepayipi lensimbi engagqwali yendawo yonke, elisetshenziswa kabanzi ukwenza imishini nezingxenye ezidinga ukusebenza okuhle okuphelele (ukumelana nokugqwala nokubumbeka).

Ipayipi lensimbi engu-304 linokumelana nokugqwala okuhle kakhulu kanye nokumelana nokugqwala okuhle kwe-intergranular.

I-304 steel pipe impahla inokumelana nokugqwala okuqinile ku-nitric acid ngaphansi kwezinga lokushisa elibilayo nokugxila≤65%.Futhi inokumelana nokugqwala okuhle kwesisombululo se-alkali kanye nama-acid amaningi e-organic kanye ne-inorganic.Uhlobo lwensimbi ephezulu ye-alloy engamelana nokugqwala emoyeni noma endaweni yokugqwala kwamakhemikhali.Insimbi engagqwali iwuhlobo lwensimbi enobuso obuhle nokumelana nokugqwala okuhle.Ayidingi ukwelashwa okungaphezulu okufana nokufakwa kombala, kodwa inikeza ukudlala okugcwele ezindaweni ezikhona zensimbi engagqwali.Isetshenziswa ezicini eziningi zensimbi, ngokuvamile ebizwa ngokuthi insimbi engagqwali.Izinsimbi eziphezulu ze-alloy ezifana ne-13 chromium steel kanye ne-18-8 chromium-nickel steel zimelela izakhiwo.

Njengensimbi engagqwali futhi ekwazi ukumelana nokushisa, ipayipi lensimbi elingu-304 liwumshini osetshenziswa kakhulu ukudla, okokusebenza kwamakhemikhali jikelele kanye nemboni yamandla e-athomu.
