There seems to be some disconnect with our platers and ASTM. The platers feel that 3 hours minimum at 350 degrees F should be adequate for spring steel with a Rockwell of 43 C scale. ASTM B850 recommends a minimum of 16 hours at 374 degrees to 428 degrees F. That is a very LARGE difference. The more I am learning, the more I see that this could be a major problem. I would like to solve this once and for all because a lot of our business is steel springs that are plated. :mg:
