69111 (0Cr12Mn5Ni4Mo3Al) is semi-austenitic precipitation hardening stainless steel. It has good corrosion resistance and high strength at medium and high temperature. Its tensile strength is ≥1570 MPa and its elongation is ≥3%. Its high strength, long life and non-deformation characteristics under strong external force are irreplaceable for general stainless steel materials.
