I just received 2 bars(1-1/2 x 36” x 3/16”) CPM-154 and 2 bars of CPM-S35VN from Admiral Steel and there is nothing written on them to indicate this. 2 bars have pink on the ends and the other 2 bars have 416 SS on them. Anybody know how to identify and did they send me 416 stainless steel by mistake?
