Thanks for the link, Rich.
"surgical steel" is somewhat of a misnomer. There are three general classifications of stainless steel: Ferritic, Austinetic, and Martinsetic. There are more than 30 specific alloys of stainless steel listed the the hand book: "Metals And How To Weld Them
". At least two could be used during surgery. 440C Martinsetic for the scalpel,which is very hard and also used in pocket knives, and Austinetic Stainless, likely used in the bendable staples used frequently instead of stitches. There are also pins, ball joints and other possible uses of stainless steel in surgery. Which then, is "surgical stainless"?
The only way to know what steel a manufacturer uses is if
they will tell you. I once wrote to Kershaw and pointed out that their advertisement stated that they used, "an AUS series high carbon
steel", which, if they used an Austenitic stainless, it would be a low carbon
steel. I knew that Austenitic stainless steel get their hardness from the Chrome and Nickle, not carbon. However, Kershaw uses a sub-zero quench to get the properties they want.
Of course, they never answered my letter. Do not interpret this post as being anti-Kershaw, l like their knife steel very much.
