Chrome 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 been made from ferrochrome[3] since it was developed around 1877 by J.

B. Boussingault and Henri Aimé Brustlein [fr] of Jacob Holtzer steelworks in Unieux, France.
