l Ke kū'ē maikaʻi loa i ke koʻikoʻi ʻana o ka corrosion ma muli o ka nui o ka nui o ka nickel content.
l Pitting and crevice corrosion, intergranular corrosion resistance.
l ʻAʻole kūʻē ka papa 904L i ka waikawa nitric.
l Ka hoʻokumu maikaʻi, paʻakikī a me ka weldability, ma muli o ka haʻahaʻa haʻahaʻa carbon, hiki ke welded me ka hoʻohana ʻana i kekahi ʻano maʻamau, ʻaʻole hiki ke paʻakikī ʻo 904L e ka mālama wela.
l Non-magnetic, 904L he kila kila Austenitic, no laila, loaʻa iā 904L nā waiwai hoʻolālā Austenitic.
l Heat Resistance, Grade 904L stainless steels e hāʻawi i ka pale oxidation maikaʻi.Eia nō naʻe, hāʻule ka paʻa o kēia papa i nā wela kiʻekiʻe, ʻoi aku ma luna o 400°C.
