This is not to say that stainless steel cannot be heat treated. The heat treatment process actually causes the bolt to undergo phase transformation under solid high temperature conditions, and promotes the austenitization of the bolt surface, thereby increasing the hardness. However, 304 stainless steel itself has an austenitic structure. This stainless steel does not undergo phase transformation in the solid state, but it will be "sensitized" after heat treatment and quenching, and its strength and corrosion resistance will be reduced. The ability to imitate rust will also be reduced. becomes relatively easy to damage. This is unwise. Therefore, austenitic stainless steel is not recommended as a heat treatment process, and ferritic stainless steel is the same.
Moreover, the strength of stainless steel bolts is not low, so it is not suitable for heat treatment. But if there are other conditions, you can also choose solution treatment and immobilization treatment to discuss the corrosion resistance of high stainless steel bolts. In general, the editor of the manufacturer of eye bolts recommends that the surface of stainless steel bolts should not be heat treated, so specific problems should be analyzed in detail.
