Steel Properties
1.4028 is a martensitic chromium grade group of stainless steels designed for hardening and tempering. Steel is on the list of related counterparts that are groups of materials without nickel, containing an average of 13% of chromium, which is mainly distinguished by the carbon content in the chemical composition and thus the higher endurance properties.
