"Surgical steel" sounds reassuringly medical. "Hypoallergenic" is plastered across half the body jewellery for sale online. So why do professional piercers consistently recommend titanium instead — and warn clients away from steel for fresh piercings?
The answer comes down to one element: nickel.
Implant-grade titanium ASTM F-136 contains no biologically reactive nickel and is recommended by the Association of Professional Piercers for fresh piercings. Surgical stainless steel 316L contains 10–14% nickel, which is bound in the alloy but can still leach in small amounts and trigger reactions in nickel-sensitive individuals. For new piercings, titanium is the safer choice.
What Surgical Steel Actually Is
"Surgical steel" is not a single regulated material. The most common variant in body jewellery is 316L stainless steel — sometimes upgraded to 316LVM. Its composition is roughly:
• Iron — base metal, around 65%
• Chromium — 16–18% (gives corrosion resistance)
• Nickel — 10–14%
• Molybdenum — 2–3%
• Carbon, manganese, silicon — small amounts
The nickel is part of the alloy structure. In healed skin, contact for short periods, and dry conditions, the nickel release stays below the EU REACH limit of 0.5 µg per square centimetre per week. In a fresh piercing — wet, warm, full of inflammatory fluid, in continuous 24/7 contact — the conditions are very different.
Why Nickel Matters
Nickel allergy is the most common contact allergy in Europe. Roughly 12–17% of women and 5% of men have a documented sensitivity.

What Implant-Grade Titanium Is
Implant-grade titanium for body jewellery comes in two standards: ASTM F-136 (Ti-6Al-4V ELI) and ASTM F-1295 (Ti-6Al-7Nb). Both contain no nickel as an intentional alloying element.

| Property | Titanium F-136 | Surgical Steel 316L |
|---|---|---|
| Nickel content | Effectively zero | 10–14% |
| APP-approved for fresh piercings | Yes | No (only F-138 implant steel) |
| Weight | ~45% lighter | Heavier |
| Corrosion resistance | Exceptional | Good (pitting possible) |
| Cost | Higher | Lower |
"But My Steel Earrings Have Never Bothered Me"
This is the most common pushback we hear, and it is fair. Many people wear steel earrings in long-healed lobes for years with no issue. The problem is not steel jewellery in healed piercings — it is steel jewellery in fresh ones, where the wound environment dramatically increases nickel release.
There is also the matter of latent sensitisation. Repeated low-level nickel exposure can build up over years until one day the body crosses the threshold and reacts.
When Steel is Actually Fine
Implant-grade ASTM F-138 surgical steel — not ordinary 316L — is APP-approved for fresh piercings. The differences are tighter purity requirements and lower interstitial elements. F-138 jewellery is rare and usually as expensive as titanium.
For healed piercings, especially earlobes, well-made steel jewellery is generally tolerated. Just do not start a new piercing with it.
Frequently Asked Questions
Is 316L surgical steel hypoallergenic?
Hypoallergenic is a marketing term with no regulated definition. 316L contains 10–14% nickel and can cause reactions in nickel-sensitive individuals, especially in healing piercings.
Will I definitely react to surgical steel?
Not necessarily. Most people tolerate steel without obvious reaction. The risk depends on your nickel sensitivity, the wound state, the alloy quality, and exposure time.
Is titanium worth the extra cost?
For a fresh or healing piercing, yes. Faster healing, lower complication risk and a longer wearable lifespan more than offset the typical 20–40% price difference.
Can I switch from steel to titanium during healing?
Once your piercing has settled (usually after the initial inflammation subsides — often 2–6 weeks depending on placement), a professional piercer can swap your jewellery to titanium.
