Mukufambira mberi kwakakosha,904L simbi isina ngurayave chinhu chinodiwa zvikuru mumaindasitiri anodziya zvakanyanya, zvichichinja nzira iyo masevhisi akasiyana-siyana anobata nayo kupisa kwakanyanya. Nekudzivirira kwayo kupisa kwakanyanya uye kutsungirira ngura, simbi isingatsvi ye904L yazvigadzira sarudzo yekushandisa zvakanyanya apo kupisa kwakanyanya kunonetsa.
Kukwezva kwesimbi isingatsvi ye904L kuri mukugadzirwa kwayo kwakasiyana uye hunhu hwayo. Iyi alloy ine huwandu hwakakwira hwe chromium ye23-28%, pamwe chete nekabhoni shoma uye huwandu hwakawanda hwe nickel (19-23%). Hunhu uhwu hunobatsira mukukwanisa kwayo kuchengetedza chimiro chayo uye kuramba oxidation kunyangwe mumamiriro ezvinhu anowanzo kukonzera kuora kwakanyanya mune zvimwe zvinhu.
