    4: 431 steel mechanical properties

        The mechanical properties mainly include tensile strength, yield strength, elongation, area or reduction, hardness, impact value, non-metalic inclusion etc. Different heat treatment, the mechanical properties will be different, such as annealed, Solid Solution. If you want to know the properties, kindly contact the salesman.
