Hello, Group. Here's the micro-structure photograph of the A286 special locknut we manufacture. You can see that the grain sizes are all over the place; what could be the cause? Contaminants inthe material? Improper heat treating? These parts were solution treated and then aged per customer specs. The material came from Carpenter Technology. TIA, Dave Griffith Monterey Machine Products For micro-structure photo please go to:
