    21: Austenitic stainless steels may be magnetized by cold working.2: Depending on what materials they are made of, some precipitation hardening stainless steels are not magnetized by solution heat treatment.

    High corrosion resistance and good cold workability due to high ductility and toughnessSuperior weldability and excellent properties at both low and high temperatures

    Various mechanical properties due to quench hardening Relatively inexpensive due to lower Ni content

    Household products, building materials, automobile parts, and various industrial plants
