Esigabeni esibalulekile,Amabha ensimbi engagqwali angu-904Lziye zavela njengezinto ezithandwa kakhulu ezimbonini ezishisa kakhulu, zaguqula indlela imikhakha eyahlukene ephatha ngayo izindawo ezishisa kakhulu. Ngokumelana kwayo nokushisa okumangalisayo kanye nokuqina kokugqwala, insimbi engagqwali engu-904L isizibekele inketho yokusetshenziswa okubalulekile lapho amazinga okushisa aphezulu eba yinselele.
Ukukhanga kwensimbi engagqwali engu-904L kusekubunjweni kwayo okuyingqayizivele kanye nezakhiwo zayo. Le alloy ine-chromium ephezulu engu-23-28%, kanye ne-carbon ephansi kanye nokuqukethwe okuphezulu kwe-nickel (19-23%). Lezi zimfanelo zinegalelo ekhonweni layo elimangalisayo lokugcina ubuqotho besakhiwo nokumelana ne-oxidation ngisho nasezimweni ezivame ukubangela ukuwohloka okukhulu kwezinye izinto.
