Why do 304 stainless steel screws need to undergo solid solution treatment?
Sometimes when customers customize stainless steel screws, they may ask about the surface treatment process of stainless steel screws. Among them, they may ask why stainless steel screws need to undergo solution treatment. Here, we will briefly introduce the solution treatment, which is a surface treatment method for screws. It refers to heating the alloy to a high-temperature single-phase zone to maintain a constant temperature, allowing the excess phase to fully dissolve in the solution and then quickly cool down, Heat treatment process to obtain supersaturated solid solution.

So what are the benefits of solid solution for stainless steel screws? The main purpose of solid solution treatment is to improve the performance of stainless steel screws, especially the corrosion resistance of stainless steel screws. By heating the solid solution treatment, carbides are dissolved in austenite and this state is kept at room temperature, thereby achieving an improvement in corrosion resistance. Unless otherwise specified, solid solution treatment is required for 304 stainless steel, which not only improves the plasticity and toughness of the steel and alloy, but also prepares for precipitation hardening treatment. Fully dissolve various phases in stainless steel alloys, strengthen the solid solution of stainless steel, improve toughness and corrosion resistance, eliminate stress and softening, and facilitate further processing or forming.
