Black Oxide Steel Sheet

Mid temperature blackening processes offer dimensional stability smut free finishes and high quality results.

Black oxide steel sheet.

To achieve maximal corrosion resistance the black oxide must be impregnated with oil or wax. With a uniform 0 000030 inch 1 micron thickness the porous crystalline structure of the black finish makes it an excellent absorbent base for a rust preventive top coat. It is used to add mild corrosion resistance for appearance and to minimize light reflection. The type ab point has the conical tip of a type a point with the finer spaced threads of a type b point.

The black stainless steel is available in 304 and 316 stainless steel and offers an attractive finish for general 304 and harsh environments 316. Epi s mid temperature black oxide process kool blak 225 blackens steel in 30 45 minutes and converts it to black iron oxide magnetite which provides a glossy black finish as well as protection for the part. Black oxide or blackening is a conversion coating for ferrous materials stainless steel copper and copper based alloys zinc powdered metals and silver solder. The black oxide finish steel sheet metal screw with truss head and phillips drive has a type ab point for forming threads in thin metals between 0 015 and 0 050 thick and resin impregnated plywood.

The pvd physical vapor deposition surface treatment is quote durable and is actually harder than the stainless steel surface itself. This sounds great but don t misunderstand.
