Martensite
We supply martensitic stainless cold rolled steel strip in both a hardened and tempered state and as an annealed version with a ferritic microstructure for better formability and subsequent piece hardening. In addition, this material is also available in a version that has been rolled to increase its tensile strength.
Martensitic stainless steel plays an important role in applications where both a high degree of corrosion resistance and resistance to wear are required. This is particularly important for cutlery, tools, and structural housing components that are exposed to a corrosive environment.
Spheroidize-annealed (2R), cold rolled, or martensitically hardened and tempered
Our customers have the choice – our stainless steel versions for martensitic hardening and tempering are available in spheroidize-annealed or cold rolled versions. Alternatively, we can supply the desired material already martensitically hardened and tempered. In the latter case of hardening and tempering on our premises, we have a very special skill: thanks to a sophisticated hardening process, we have the ability to martensitically harden and temper steel strip up to 4 mm thick. As a result, we offer martensitic stainless steels in an exceptionally wide range of thicknesses.
