Surgical steel was the term used for stainless steel prior to 1920.
The first “stainless steel” was developed around 1870 and was used for bone screws and cutlery.
It was actually developed to replace silver for knives, spoons and forks, but its corosion resistance lead to its use for implants. This was roughly what the AISI now classify as 302.
In 1920, a new grade of stainless was developed and quickly took over in prominance. This was 18-8 or more commonly known as 304.
Since its use was becoming more wide spread, the term surgical steel was changed to stainless steel.
In 1950 we saw 316L being produced… at this time all implants switched over to 316L.
Depending on which metals are used and which quantity of those are mixed, different characteristics are obtained. The steel most commonly used to make body piercing jewelry is the one classified by the AISI as 316L(VM),where 316 is the ‘family’ of steel, L stands for Low Carbon Content and VM for Vacuum Melted. This last process is not always done for the steel used for Body Jewelry.
About 30 years ago the increasing popularity for this application, pushed both the ASTM and the ISO to study and define the structural characteristics necessary for the 316L(VM) steel to have an optimized performance when used for implants in the human body, and to create standard sets of tests necessary to determine if a stock of stainless steel meets those characteristics.
ASTM made the F138 designation and the ISO the 5832-1: both very similar.
- The code 316L(VM) only describes a stainless steel with a high corrosion resistance.
- The term often heard ‘Surgical Steel’ it is only a marketing tool.
- ONLY Stainless steel certified to meet the ASTM F138 or the ISO 5832-1 designations can be called implant grade.
If the metals composing the 316L(VM) stainless steel (like Chromium and Nickel) leach outside the alloy bond into the body, they could lead, in time, to sensitivity and dermatitis.
To minimize risks of skin complications, paying attention to the implant grade certification is necessary when buying Stainless Steel body jewelry, as much as to its smooth, flawless and high polished surface finish.
Unfortunately, most of the body piercing jewelry on the market today does not meet those safety requirements.
Not to worry. All of Anatometals Stainless Jewelry are ASTM F138 certified Implant Grade Surgical Stainless. They also all have a mirror finish making it safe to use on the human body.
Implant grade surgical stainless is a very hard, durable and insoluble in water, therefore rarely causes any allergic reaction.（※There are although some people who have suffered an allergic to stainless steel. If you are worried, please take an allergy test at the doctor to be safe. Most of the time, the allergic reaction is caused not by the stainless steel but from other materials that have been blended.）

How to care for your Stainless Jewelry
You must autoclave your jewelry when used in your initial piercing.
When using it in a healed piercing, wash your jewerly with soap and warm water and wipe it down with Propanol or other alcohol.
After wearing it for awhile, remember to wash it often in the shower. Please don’t leave soap or shampoo on the piercing, which can cause irritation and problems. Take off your jewelry at times and wash your piercing and your jewelry with warm water.
Please note that disinfectant, cleaner or chlorine can corrode stainless steel.
