Ukusetshenziswa kanye nezakhiwo ze-304 yensimbi engagqwali, ibha yensimbi engagqwali engu-304, ngokusho kwe-United States AISI standard, insimbi engagqwali enezinombolo ezintathu zesi-Arabhu. Izigaba zedijithi yokuqala, inombolo yedijithi yesibili ukuya kweyesithathu. Idijithi yokuqala engu-3 yokuvula insimbi engagqwali engu-300-chungechunge iyisakhiwo se-Cr-Ni se-austenitic stainless steel.
