Our martensitic stainless steels are the perfect choice when a combination of corrosion resistance, high hardness, and high ductility are required. 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.
Martensitically hardenable or hardened and tempered precision steel strip with high hardness and ductility
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.
