For chrome steel as a rarely used historical or alternative name, see stainless steel.
Chrome steel is the name for any one of a class of non-stainless steels such as AISI 52100, SUJ2, 100Cr6,[1] En31, 100C6, and DIN 5401 which are used for applications such as bearings, tools, drills and utensils. Like stainless steel, chrome steels contain chromium, but do not have the corrosion-resistant properties of stainless steel.[2] It has historically been known as ferro-chrome.[3]
