Performance and application:
High permeability and mechanical properties, good heat resistance and corrosion resistance, high fatigue strength and good heat resistance, no temper embrittlement, machinability is acceptable when the cold plastic deformation is low, welding poor, low hardenability, general conditioning and infiltration helium before use.
Uses:
Used in the manufacture of high fatigue strength, high wear resistance, precise dimensions after heat treatment, high strength helium permeability of various sizes small parts. |

Performance and application:
Can not be directly quenched after carburizing, quenching in a high-temperature tempering is necessary before to reduce the surface of a large number of retained austenite, plastic deformation of cold medium workability acceptable white point of sensitivity, and have a tendency to temper brittleness.
Uses:
Manufacturing requirements for performance than 12Cr2Ni4 large carburized parts can also be used in the manufacture strength, toughness of quenched and tempered high-pieces. | | |
