"Coloring 316 stainless steel"
We manufacture an industrial type of lock and key that is machined from 316 stainless steel and then the items are electroplolished. The key is a bulkier style key than your standard house or car key. We are trying to figure out a way to color code the keys. Since the lock is comprised of 316 stainelees steel, is there a chemeical process to color coat the steel? Plastic slip-ons or dipping is not an option since the key can be placed in high heat areas. We need red, yelow, green, and blue.Sean T McGuinness
