Hardox 450 isn't intended to be heat treated. These tooth bars are cut with a laser and since they're custom in terms of overall length, edge thickness, number of holes, diameter of holes, distance between holes, center of hole to outside edge, center of holes to leading edge and inside width of the bucket, it stands to reason that each tooth bar is a custom addition to the cutting program. They're making tooth bars for numerous models and manufacturers.
Add in the time and effort to load a sheet into the laser cutter, along with all the other patterns that they need to cut for other products, they probably wait until they have enough sheets to run before they do it. Then the bar has to be cleaned up, brackets welded on, cleaned again and painted. Is 9 weeks a big deal for me ... heck no.
Yet again I'm shaking my head at the same three or four members who time and time again want to bring EA down complaining about every possible aspect of the company that is employing American workers. None of this affects you in any way since you don't own their products, haven't placed any orders, aren't waiting on any orders, and don't intend to buy from EA. You really are the most bitter, miserable, "know-it-all" individuals I've ever encountered on a forum. EA has been around a long time and have proven to be a successful company making good products that are in demand. Rather than congratulate them on that you all seem intent on convincing everyone else that you could do it all so much better. Yep, ego is a bitch!
