Otherwise known as 'Type 316 Stainless Steel', A4 stainless steel contains carbon, silicon, manganese, phosphorous, sulphur, chromium, molybdenum, and nickel. These elements make fixings manufactured from A4 steel very resistant to corrosion and less reactive to other materials. Marine environments (by the sea), photographic chemicals, surgical implants as well as solutions of sulfuric acid, chlorides, bromides and iodides, most notably resistance to pitting corrosion in chloride environments where traditional A2 stainless steel falls short.
