Novel fine grain stainless steels are a group of 300-series stainless steels. They are a stronger, yet formable alternative for general stainless steels such as EN 1.4307 (AISI 304L) and EN 1.4404 (AISI 316L). Their yield strength levels can be varied from 350 MPa up to 800 MPa and their elongation properties range from 50% to 20% respectively.
The phenomena behind the properties of these unique stainless steels is based on grain refining. Small grain size gives the steels excellent surface quality, which is especially prominent after cold forming.
The steels can be used in applications where extra strength is needed or where surface quality is important. The steels can be used as an alternative to existing 300-series steels in many applications as their composition complies with standard EN10088-2.
The product is supplied in cold rolled, annealed and pickled condition.
Possible thicknesses range from 0.05mm up to 3.5mm in coil and sheet forms.
