304 waja tahan karat minangka jinis umume, kalebu stainless steel austenit. Iki digunakake sacara umum ing industri pengecoran. Komposisi standar 304 stainless steel yaiku 18% kromium ditambah 8% nikel. Iki non-magnetik. Yen isi impure dhuwur, kadang-kadang bakal nuduhake magnetisme sing kurang sawise diproses. Daya tarik sing ringkih iki mung bisa diilangi kanthi perawatan panas. Kagolong saka stainless steel sing struktur metalografi ora bisa diganti karo perawatan panas.
Ing standar internasional, biji sing padha karo 304 stainless steel yaiku: 1,4301, X5CrNi18-10, S30400, CF8 lan 06Cr19Ni10. Minangka salah sawijining bahan stainless steel sing paling akeh digunakake, casting stainless steel 304 duwe peran penting kanggo ngawula para pelanggan.
