Hence the keywords in critical and sterile processing are: productivity and compliance with regulatory standards. One of the often overlooked but critical problems is ferrous contamination in sterile process manufacturing from steel hand tools. Most hand tools are either Chrome Vanadium or Black Phosphate. Chrome Vanadium tools have a coating that prevents oxidation and corrosion. This makes chrome vanadium suitable for an autoclave and can be sterilized for acceptable use in critical environments. However, each successive autoclave cycle deteriorates the coating, causing it to chip, flake, and peel.
