022Cr23Ni4MoCuN — stainless Steel: Composition, Properties & Applications
Also known as: 022Cr23Ni4MoCuN
Lean duplex stainless steel. (GB/T 20878; equiv UNS S32304 / EN 1.4362). Nominal values—confirm mill certificate.
CHEMICAL COMPOSITION
C:≤0.030;Cr:21.0-23.0;Ni:3.0-5.5;N:0.05-0.20
MECHANICAL PROPERTIES
Tensile:≥600 MPa;Yield:≥400 MPa
TYPICAL APPLICATIONS
经济型双相。,"Plate
AVAILABLE FORMS
Tube"
STANDARDS & EQUIVALENT GRADES
T 20878 022Cr23Ni4MoCuN; UNS S32304 / EN 1.4362
HEAT TREATMENT
Annealed at 780–850 °C and air cooled; stabilize at 600–800 °C to avoid 475 °C embrittlement; not hardenable by heat treatment.
PROCESSING PRECAUTIONS
Avoid welding in the 475 °C embrittlement and sigma-phase ranges; use matched filler and minimize heat input. Good resistance to stress-corrosion cracking.
