I roto i tētahi whanaketanga nui,Ngā pae kowiri tira 904Lkua puta ake hei rauemi tino pai i roto i ngā ahumahi pāmahana teitei, e huri ana i te huarahi e whakahaere ai ngā momo rāngai i ngā taiao wera nui. Nā tōna ātete wera me te pakari ki te waikura, kua whakatūria te maitai kore waikura 904L hei kōwhiringa matua mō ngā tono nui e wero ana i ngā pāmahana teitei.
Ko te āhua o te maitai kore waikura 904L kei roto i tōna hanganga ahurei me ōna āhuatanga. He nui ake te ihirangi chromium o tēnei koranu, arā, 23-28%, me te iti o te waro me te nui ake o te nikara (19-23%). Ka whai wāhi ēnei āhuatanga ki tōna kaha whakamiharo ki te pupuri i te hanganga pai me te ātete ki te waikura ahakoa i roto i ngā āhuatanga e tino kino ai ētahi atu rauemi.
