This layer shields the metal from corrosion and enhances its durability.<\/p>\n\n<\/div>\n<\/div>\n<div id=\"faq-question-1714033684562\" class=\"rank-math-list-item\">\n<h3 class=\"rank-math-question\">Which metals can be passivated?<\/h3>\n<div class=\"rank-math-answer\">\n\n<p>Mainly stainless steel can be passivated. Its chromium content allows a stable oxide layer to form, protecting it from corrosion.<\/p>\n\n<\/div>\n<\/div>\n<div id=\"faq-question-1714033691418\" class=\"rank-math-list-item\">\n<h3 class=\"rank-math-question\">Why passivate?<\/h3>\n<div class=\"rank-math-answer\">\n\n<p>Passivation prevents corrosion \u2014 especially when stainless steel is exposed to moisture, salts, or acids. It also improves aesthetics by ensuring a uniform finish and enhances the material\u2019s resistance to harsh environmental factors.<\/p>\n\n<\/div>\n<\/div>\n<div id=\"faq-question-1714033700268\" class=\"rank-math-list-item\">\n<h3 class=\"rank-math-question\">What acid is used for passivation?<\/h3>\n<div class=\"rank-math-answer\">\n\n<p>Nitric acid (HNO3) is most commonly used for passivation. A mixture of chromic acid (H2CrO4) and sulfuric acid (H2SO4) can also be employed. These chemicals help establish a stable oxide layer that protects the steel from corrosion.<\/p>\n\n<\/div>\n<\/div>\n<\/div>\n<\/div>","protected":false},"excerpt":{"rendered":"","protected":false},"author":8,"featured_media":0,"parent":121,"menu_order":0,"comment_status":"closed","ping_status":"closed","template":"","meta":{"_acf_changed":false,"footnotes":""},"class_list":["post-1147","page","type-page","status-publish","hentry"],"acf":[],"_links":{"self":[{"href":"https:\/\/trawialnia.eu\/en\/wp-json\/wp\/v2\/pages\/1147","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/trawialnia.eu\/en\/wp-json\/wp\/v2\/pages"}],"about":[{"href":"https:\/\/trawialnia.eu\/en\/wp-json\/wp\/v2\/types\/page"}],"author":[{"embeddable":true,"href":"https:\/\/trawialnia.eu\/en\/wp-json\/wp\/v2\/users\/8"}],"replies":[{"embeddable":true,"href":"https:\/\/trawialnia.eu\/en\/wp-json\/wp\/v2\/comments?post=1147"}],"version-history":[{"count":2,"href":"https:\/\/trawialnia.eu\/en\/wp-json\/wp\/v2\/pages\/1147\/revisions"}],"predecessor-version":[{"id":1163,"href":"https:\/\/trawialnia.eu\/en\/wp-json\/wp\/v2\/pages\/1147\/revisions\/1163"}],"up":[{"embeddable":true,"href":"https:\/\/trawialnia.eu\/en\/wp-json\/wp\/v2\/pages\/121"}],"wp:attachment":[{"href":"https:\/\/trawialnia.eu\/en\/wp-json\/wp\/v2\/media?parent=1147"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
