When you're shopping for piercing jewelry, "surgical steel" sounds safe. It sounds medical. It sounds like someone has tested it and given it a pass.
But the truth is that "Surgical steel" is a marketing term. understanding what it actually means (versus what implant-grade means) is the difference between jewelry that heals cleanly and jewelry that irritates you for months.
What Does "Surgical Steel" Actually Mean?
There is no regulatory definition for "surgical steel" in the context of piercing jewelry. The term is used loosely to describe stainless steel alloys—most commonly 316L or 316LVM—that are also used in some surgical instruments. But surgical instruments are temporary. They go into your body and come right back out. Piercing jewelry stays in your tissue, sometimes for months at a time.
Surgical steel typically contains 8–12% nickel by composition. Nickel is one of the most common contact allergens in the world. Even with low migration rates, prolonged contact, especially in a healing piercing, can trigger irritation, prolonged healing, or allergic reactions. The EU regulates nickel release in jewelry sold to consumers (the EU Nickel Directive), but in the US, there are no federal limits. What's sold as "surgical steel" piercing jewelry varies widely.
The bottom line: surgical steel isn't bad, but it also isn't a safety standard.
What Does "Implant-Grade" Actually Mean?
Implant-grade is a real standard.
Materials labeled implant-grade must meet specific ASTM (American Society for Testing and Materials) or ISO standards developed for materials that live inside the human body long-term—think orthopedic implants, joint replacements, and bone screws. These standards govern:
-
Alloy composition: what's in it, in precise percentages
-
Surface finish: how smooth it must be at a microscopic level (rougher surfaces trap bacteria and increase ion migration)
-
Nickel content and release rates: how much nickel can leach out over time
-
Biocompatibility: testing that confirms the material doesn't cause adverse tissue reactions
The most common implant-grade materials you'll see in quality piercing jewelry:
Implant-grade titanium (ASTM F136): this is what we use at Oh Kira! It is the gold standard. Grade 23 titanium alloy. Contains no nickel. Lightweight, extremely biocompatible, and uniquely, it can be anodized to produce vivid colors without dyes or coatings. Recommended by the Association of Professional Piercers (APP) as the first-choice material for new piercings.
Implant-grade steel (ASTM F138 / 316LVM): the vacuum-melt version of 316L steel. More controlled manufacturing process, lower nickel content, and a higher surface polish standard than regular surgical steel. Generally safe for healed piercings; some people with nickel sensitivity may still react.
Implant-grade niobium: nickel-free, hypoallergenic, and can be anodized like titanium. Less common but works for sensitive skin.
Solid gold: nickel-free and biocompatible for most people. The key is solid gold, not gold-filled or gold-plated, and verifying there's no nickel in the alloy.
So Is Surgical Steel Safe?
For a healed piercing in someone without a nickel allergy, it is probably fine. For a fresh piercing, a healing piercing, or anyone with sensitive skin or a known nickel sensitivity, it is not ideal.
The APP's position is clear—for initial piercings, implant-grade titanium or implant-grade steel (316LVM) should be the minimum standard. Many professional piercers now default to implant-grade titanium exclusively for new piercings because it eliminates the nickel variable entirely.
Why Most Cheap Piercing Jewelry Skips This
Implant-grade materials cost more. ASTM F136 titanium costs more to source and produce than generic stainless steel. A brand that markets on price will almost always use lower-grade steel and rely on the words "surgical" or "hypoallergenic" to imply safety without committing to a standard.
"Hypoallergenic" is also unregulated, by the way. It means whatever the brand wants it to mean.
What This Means When You're Shopping
When evaluating piercing jewelry, ask:
-
What material, specifically? "Stainless steel" or "surgical steel" isn't enough. You want the alloy designation—ASTM F136, 316LVM, solid 14k/18k gold.
-
What grade? Implant-grade means something. "Surgical" doesn't.
-
Is it internally threaded or threadless? Externally threaded jewelry (where the screw threads touch healing tissue) can cause micro-abrasions. Implant-grade jewelry is almost always internally threaded or threadless.
Frequently Asked Questions
Is implant-grade titanium the safest metal for piercings?
Yes, for most people. ASTM F136 implant-grade titanium is nickel-free, extremely lightweight, and passes the highest biocompatibility standards used for permanent implants. It's the material professional piercers most commonly recommend for new piercings.
Can I wear surgical steel if I have a nickel allergy?
Not recommended. Surgical steel contains nickel. Even with low migration rates, a nickel allergy can react to prolonged contact during healing. Implant-grade titanium or niobium are the better options.
What does ASTM F136 mean?
ASTM F136 is the American standard for titanium alloy used in surgical implants. It specifies the exact composition (Ti-6Al-4V ELI), surface finish requirements, and mechanical properties. When you see ASTM F136 on jewelry, it means the material was manufactured to implant-grade specification — not just marketed that way.
Is gold better than titanium for piercings?
Both can be excellent — with caveats. Solid 14k or 18k gold in a nickel-free alloy is biocompatible and beautiful. The risks with gold are plated jewelry (the plating wears off, exposing base metal) and alloys that contain nickel as a hardener. Titanium has the advantage of being verifiably nickel-free by composition.
Why do my piercings always get irritated?
Irritation bumps and prolonged healing are often caused by one of three things: movement/trauma, improper aftercare, or material reaction. If aftercare is solid and you're not bumping the jewelry, the material is worth looking at. Switching to implant-grade titanium resolves material-related irritation for most people.
At Oh Kira!, every piece is made from implant-grade materials, because your piercings deserve the same standard as a permanent implant, not a marketing term.
