                                Grade 7 titanium (UNS R52400) is commercially pure titanium alloyed with 0.12\u20130.25% palladium. That trace Pd addition dramatically improves corrosion resistance in reducing acids \u2014 delivering 40\u00d7 to over 1,000\u00d7 better performance than Grade 2 in hydrochloric and sulfuric acid environments. Grade 11 shares the same Pd content but builds on a lower-interstitial Grade 1 […]<\/p>\n","protected":false},"author":1,"featured_media":0,"comment_status":"closed","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[1],"tags":[],"class_list":["post-4069","post","type-post","status-publish","format-standard","hentry","category-blog"],"_links":{"self":[{"href":"https:\/\/hontitan.com\/ko\/wp-json\/wp\/v2\/posts\/4069","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/hontitan.com\/ko\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/hontitan.com\/ko\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/hontitan.com\/ko\/wp-json\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/hontitan.com\/ko\/wp-json\/wp\/v2\/comments?post=4069"}],"version-history":[{"count":2,"href":"https:\/\/hontitan.com\/ko\/wp-json\/wp\/v2\/posts\/4069\/revisions"}],"predecessor-version":[{"id":4081,"href":"https:\/\/hontitan.com\/ko\/wp-json\/wp\/v2\/posts\/4069\/revisions\/4081"}],"wp:attachment":[{"href":"https:\/\/hontitan.com\/ko\/wp-json\/wp\/v2\/media?parent=4069"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/hontitan.com\/ko\/wp-json\/wp\/v2\/categories?post=4069"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/hontitan.com\/ko\/wp-json\/wp\/v2\/tags?post=4069"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
