CarTech EnduraMet 304LN stainless is a nitrogen-strengthened version of Carpenter Stainless Type 304L. By means of solid solution strengthening, the nitrogen provides significantly higher yield and tensile strength as annealed than Type 304L without adversely affecting ductility, corrosion resistance or non-magnetic properties. In the hot rolled unannealed condition, yield strengths of 75 ksi (518 MPa) or higher can be achieved for bar diameters up to 1.375 in. (34.925 mm).

Applications:
Rebar has been a primary application for CarTech EnduraMet 304LN stainless. Specific rebar applications have included bridge decks, barrier and retaining walls, anchoring systems, chemical plant infrastructure, coastal piers and wharves, bridge parapets, sidewalks, and bridge pilings. For improved chloride corrosion resistance in these applications, CarTech EnduraMet 2205 stainless and CarTech EnduraMet 316LN may be considered.

Because of its low magnetic permeability, CarTech EnduraMet 304LN has been used in concrete rebar applications in close proximity to sensitive electronic devices and magnetic resonance medical equipment. The higher strength capability, 75 ksi (518 MPa) minimum yield strength, of CarTech EnduraMet 304LN is an added economical advantage.
