X2CrNiN23-4
1.4362Lean duplex stainless steel (SAF 2304 / UNS S32304) with reduced Mo and Ni content compared to 2205. Cost-effective alternative to austenitic 316L with ~2× yield strength (400 MPa) and good stress corrosion cracking resistance. No Mo addition — relies on Cr+N for corrosion resistance (PREN ~25). Used for storage tanks, water heaters, transport tanks, structural applications in construction (e.g. reinforcing bar), and swimming pool structures. The budget-friendly duplex option.
