END USES

Deep drawn steel – giving the name 304 DD - is widely used in severe plastic deformation processes (e.g. non-welded deep tanks, saucepans, etc.). It is a sub-class of the more common 304 and is not a grade of steel defined by the nomenclature AISI, DIN, etc. 304 steel is usually considered 304 DD with high mechanical characteristics (elongation A50 over 56/57%, RP02 under 300, etc.).

The quality of the mechanical characteristics of the material can be achieved through the presence of a high quantity of Nickel, which can also be higher than 8, however within the interval that defines AISI 304, outlined above.
