I just received some steel from admiral the other day and while I was down stairs cutting it up, I noticed something.
It has been written on indicating that it is 440C, which is what I ordered, however the ends of the bars are painted an orange color. In the past when I have ordered from other places it was painted yellow at the ends. Is this a color coding that is universal, or do different places do it different. I'd hate to send it in for heat treat and it be the wrong thing.

Thanks for the help in advance.
