022Cr19Ni5Mo3Si2N — stainless Steel: Composition, Properties & Applications
Also known as: 022Cr19Ni5Mo3Si2N
Specialty steel grade. /T 20878; equiv ASTM 444 / EN 1.4521). Nominal values—confirm mill certificate.
CHEMICAL COMPOSITION
C:≤0.025;Cr:17.5-19.5;Mo:1.75-2.50;Nb:0.20-0.60
MECHANICAL PROPERTIES
Tensile:≥430 MPa;Yield:≥250 MPa
TYPICAL APPLICATIONS
高耐蚀铁素体，抗氯。,"Sheet
AVAILABLE FORMS
Tube"
STANDARDS & EQUIVALENT GRADES
T 20878 022Cr19Ni5Mo3Si2N; ASTM 444; EN 1.4521
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.
