ʻO 400 series stainless steel he mea hao, kalapona a me chromium. No ka mea, ʻaʻohe nickel i loko.
he kila nickel-hoving stainless steel, ʻike ʻia hoʻi ʻo ke kila kila. 400 moʻo kuhiliʻole kila maʻamau
nā waiwai magnetic ma muli o kona ʻano martensitic a me ka hao.
400 moʻo kuhiliʻole kila i ikaika kū'ē i kiʻekiʻe wela oxidation, a me kona kino a me ka mechanical
ʻoi aku ka maikaʻi o nā waiwai i ka hoʻohālikelike ʻia me ke kila kalapona. ʻO ka hapa nui o 400 series stainless steels hiki ke mālama ʻia i ka wela.
