Do you know of any disastrous mistakes that occurred due to the incorrect usage of stainless steel alloys?
5 answers
We buy several different grades of stainless steel and we go to great lengths to mark up our stock so that the exact grade is known. We know of instances where grades have been stored together without identification resulting in the wrong grade of stainless being used on an application.
~Chris Carmody, Special Products Manager, Rotherham, UK
There have been countless accidents due to material failure, but no disastrous mistakes that I am aware of due to incorrect selection/usage.
