Heavy Pitting Corrosion on a Type 304 Stainless Steel Screw
Heavy pitting corrosion on type 304 stainless steel bone screw was studied. A screw head that exhibited heavy pitting corrosion attack was observed. Deep tunnels that penetrated the screw head and followed the inclusion lines were revealed. The screw was inserted in a plate made of type 316LR stainless steel and some mechanical fretting and very few corrosion pits were revealed. Type 304 stainless steel was deemed not to be satisfactory as an implant material.
