Abstract

A vacuum solid solution method for nickel-free high manganese and nitrogen is provided and relates to the technical field of metal material heat treatment. By vacuumizing, heat homogenizing, keeping the temperature in the final temperature range, deoxidation, and rapid cooling treatment, the present method forms a single austenitic structure from the raw materials, and promotes full and uniform dispersion of nitrogen carbide, providing a nickel-free high nitrogen stainless steel with more stable comprehensive performance and wider range of application.
