This guide explains what F136 actually means, how it compares to the labels you&#8217;ll see elsewhere, and how a wholesale buyer should verify material before committing to an order.<\/p>\n<h2>Why F136 Is the Standard for Piercing Jewelry<\/h2>\n<ul>\n<li><strong>Biocompatible composition<\/strong> \u2014 Ti6Al4V ELI with tightly controlled interstitial elements (oxygen, nitrogen, carbon, iron), produced for surgical implants.<\/li>\n<li><strong>Nickel-free<\/strong> \u2014 no nickel release, which matters for clients with metal sensitivities and for EU nickel-directive compliance.<\/li>\n<li><strong>Corrosion resistance<\/strong> \u2014 the passive oxide layer re-forms instantly, surviving autoclave cycles and years of skin contact.<\/li>\n<li><strong>Strength with low weight<\/strong> \u2014 about 40% lighter than 316L steel at the same volume, comfortable for cartilage and navel jewelry.<\/li>\n<li><strong>Anodizable<\/strong> \u2014 the oxide layer thickness creates the color range (no plating, no coating to chip off).<\/li>\n<\/ul>\n<h2>F136 vs. G23 vs. 316L \u2014 What the Labels Mean<\/h2>\n<table>\n<thead>\n<tr>\n<th>Label<\/th>\n<th>What it actually is<\/th>\n<th>For piercing jewelry<\/th>\n<\/tr>\n<\/thead>\n<tbody>\n<tr>\n<td>ASTM F136<\/td>\n<td>A material <em>standard<\/em>: certified Ti6Al4V ELI bar stock with documented chemistry and mechanical properties<\/td>\n<td>The benchmark. Mill certificates trace the alloy to spec.<\/td>\n<\/tr>\n<tr>\n<td>&#8220;G23 titanium&#8221;<\/td>\n<td>An industry shorthand (Grade 23 = the ELI alloy), <em>not<\/em> a certification by itself<\/td>\n<td>Meaningful only when backed by F136-standard mill certs. &#8220;G23&#8221; alone proves nothing.<\/td>\n<\/tr>\n<tr>\n<td>&#8220;Implant grade&#8221; (unqualified)<\/td>\n<td>Marketing language with no defined chemistry<\/td>\n<td>Ask what standard is behind the claim.<\/td>\n<\/tr>\n<tr>\n<td>316L surgical steel<\/td>\n<td>Marine-grade stainless, austenitic chromium-nickel alloy<\/td>\n<td>Contains 10\u201314% nickel; acceptable for healed piercings in many markets but a common sensitization source, and heavier than titanium.<\/td>\n<\/tr>\n<tr>\n<td>&#8220;Titanium plated&#8221; \/ &#8220;titanium color&#8221;<\/td>\n<td>A coating over an unknown base metal<\/td>\n<td>Not implant grade. Coating wears; base metal contacts skin.<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<p>The commonest trap in wholesale buying is <strong>&#8220;G23&#8221; stamped on jewelry made from unknown bar stock<\/strong>. Grade 23 describes the alloy \u2014 if the mill that produced the bar didn&#8217;t certify to F136 chemistry, the stamp is decoration. That is why our material claim is always the full standard: <strong>ASTM F136<\/strong>, and we treat every batch against it with pre-shipment inspection.<\/p>\n<h2>How Wholesale Buyers Should Verify Material<\/h2>\n<ol>\n<li><strong>Ask for the standard, not the grade<\/strong> \u2014 a supplier who answers &#8220;F136&#8221; with mill certificates available is in a different category from one who answers &#8220;G23, trust us.&#8221;<\/li>\n<li><strong>Check the construction<\/strong> \u2014 implant-grade pieces are internally threaded: the thread is on the bar, the receiving disc is smooth. Externally threaded posts scratch tissue on insertion.<\/li>\n<li><strong>Order a sample before the bulk buy<\/strong> \u2014 weigh it (titanium is light), check polish and thread fit, run it through your autoclave. See our <a href=\"https:\/\/titanpierce.com\/es\/sample-pack\/\">sample pack<\/a>.<\/li>\n<li><strong>Ask about the anodizing<\/strong> \u2014 F136 colors come from oxide thickness, not plating. A &#8220;color&#8221; that chips or scratches off is a coating on base metal.<\/li>\n<li><strong>Match the paperwork to the claim<\/strong> \u2014 for regulated markets (EU, and clients who ask), request material documentation with your order; we supply it on request.<\/li>\n<\/ol>\n<h2>Does F136 Cost More?<\/h2>\n<p>Certified F136 bar stock costs more than mystery alloy \u2014 but in wholesale quantities the gap is small. TitanPierce list prices run <strong>$3.90\u2013$18.00 per piece<\/strong> before tier discounts, with automatic discounts from 10% (orders $199+) to 50% ($3,199+), on a <a href=\"https:\/\/titanpierce.com\/es\/wholesale\/\">10-piece-per-style minimum<\/a>. Compared with the cost of one bad review from a reaction, the material decision pays for itself.<\/p>\n<h2>Shop F136 Titanium by Category<\/h2>\n<ul>\n<li><a href=\"https:\/\/titanpierce.com\/es\/categoria-producto\/labret-studs\/\">Labret studs<\/a><\/li>\n<li><a href=\"https:\/\/titanpierce.com\/es\/categoria-producto\/nose-rings-septum\/\">Nose rings &amp; septum<\/a><\/li>\n<li><a href=\"https:\/\/titanpierce.com\/es\/categoria-producto\/navel-rings\/\">Navel rings<\/a><\/li>\n<li><a href=\"https:\/\/titanpierce.com\/es\/categoria-producto\/straight-curved-barbell-bases\/\">Straight &amp; curved barbells<\/a><\/li>\n<\/ul>\n<p>Not sure which gauge or length your clients need?

Many studios keep steel only for healed, low-risk placements.<\/p>\n<h3>Can F136 titanium jewelry go in an autoclave?<\/h3>\n<p>Yes. Implant-grade titanium is unaffected by standard steam sterilization cycles \u2014 the oxide layer that protects the metal is stable and self-repairing.<\/p>\n<h3>How do I know my wholesale jewelry is really F136?<\/h3>\n<p>Three checks: the supplier names the standard and can provide material documentation; the pieces are internally threaded with clean machining; and a sample weighs light and passes your autoclave test. Order a sample pack and test before the bulk order.<\/p>\n<h3>What colors does F136 titanium come in?<\/h3>\n<p>Anodizing the surface at controlled voltages produces gold, rose, blue, purple, rainbow and more \u2014 the color is the oxide layer itself, so nothing can chip or fade off.<\/p>\n<p><script type=\"application\/ld+json\">\n{\"@context\":\"https:\/\/schema.org\",\"@type\":\"FAQPage\",\"mainEntity\":[\n{\"@type\":\"Question\",\"name\":\"Is ASTM F136 the same as G23 titanium?\",\"acceptedAnswer\":{\"@type\":\"Answer\",\"text\":\"Grade 23 is the alloy designation for Ti6Al4V ELI; ASTM F136 is the standard defining certified chemistry and mechanical properties for implants.
