Application:304LN Stainless Steel is used for a wide variety of home and commercial applications.
Surface treatment:No.1,2B,BA,No.4,Mirror, HL,or as customers' requirements
304LN Stainless Steel Introduction
SDJS 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).
304LN Stainless Steel Usage
Magnetic resonance imaging (MRI) scanners, reinforcing bar for structures surrounding MRI scanners, pressure vessels, cryogenic applications.
