Cutting this material on a lathe is extremely difficult, welding it will result in cracking. The only proper method what I can think of, is annealing it to reduce hardness, machining/welding it and then heat treating it to proper hardness again. Without knowing the exact alloy it's not gonna be easy... let alone to find a machine shop who will do this for you, and then there's the cost.
Good point
Ok make sure its the revised full depth nut and use thread lock then?
What abut using a centre punch on the gap between the thread and nut to deform the thread slightly?
other idea use the original 9mm nut and machine up a second one to work as a lock nut?
