022Cr11Ti — stainless Steel: Composition, Properties & Applications
Also known as: 022Cr11Ti
Automotive exhaust ferritic stainless. (GB/T 20878; equiv ASTM 409 / EN 1.4512 / JIS SUS409). Nominal values—confirm mill certificate.
CHEMICAL COMPOSITION
C:≤0.08;Cr:10.5-11.7;Ti:≥6×C
MECHANICAL PROPERTIES
Tensile:≥380 MPa;Yield:≥170 MPa
TYPICAL APPLICATIONS
汽车排气用铁素体。,"Sheet
AVAILABLE FORMS
Tube"
STANDARDS & EQUIVALENT GRADES
T 20878 022Cr11Ti; ASTM 409; EN 1.4512 / JIS SUS409
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.
