How to permanently mark stainless steel?

Question

Accepted Answer

To mark stainless steel for life, you can try several methods. One effective moreover advised method is laser annealing. This method uses a laser to alter the material&#x27;s chemicals below the surface while keeping its chromium oxide barrier. This way the mark stays fixed and the metal keeps its rust resistance. Laser engraving moreover acid etching do not work well on stainless steel because they might harm the protective layer moreover cause rust. Laser annealing creates marks with clear contrast that stand up to corrosion and harsh conditions. This approach finds use in areas such as aerospace, vehicles as well as medical tools where keeping track and long life matter. Other approaches such as electrochemical marking serve sectors that require food safety. This method produces lasting marks without harming the metal surface; it suits tasks where the metal must stay intact. Laser annealing remains preferred when marking stainless steel because it yields precise marks while keeping the metal intact.
