Black Oxide Stainless Steel

I like 316 or 316l over the 304 alloy.

Black oxide stainless steel.

As an alternative to the bright shiny aesthetic of polished raw stainless these. Black oxide like other coatings is used to provide protection to the part achieve a required appearance or achieve other desired properties. Black oxide coatings on stainless steel are common. If a dry to touch finish is needed it is important to specify either oil spin dry to touch wax or lacquer.

Use a room temperature blackening process to give steel parts satiny grey black finishes. Black oxide stainless steel nuts bolts and washers are the most common form of black oxide fastener available. A black oxide finish on plain steel has virtually zero corrosion resistance. Black oxide or blackening is a conversion coating for ferrous materials stainless steel copper and copper based alloys zinc powdered metals and silver solder.

Black oxide cable hardware. It is used to add mild corrosion resistance for appearance and to minimize light reflection. Black oxide is a form of coating used as a finish for ferrous metals stainless steel and copper and its alloys. This means that the black oxide is not deposited on the surface of the substrate like nickel or zinc electroplating.

One of its advantages over other coatings is its minimal buildup. Superior black oxide finishes for stainless steel room temperature 65 85 f room temperature black oxide processes are best for quick safe and convenient in house and even at home blackening. These terms all refer to the process of forming a black iron oxide on the surface of ferrous metals. Strip the oil off and the part will often flash rust in hours.

The black oxide process is a chemical conversion coating. The after finish is usually determined by the part configuration and the end use. It is usually waxed or oiled and sometimes lovingly maintained with light oil in some cases such as with hunting rifles. Black oxides on stainless steel and or brass alloys will yield excellent corrosion protection primarily due to their inherent properties.

Our black oxide cable and fittings are made using the same marine grade 316 stainless steel material as our traditional infill but with a chemically achieved outer coating that boosts corrosion resistance and changes the appearance. Type 303 has a high sulfur content that seems to interfere with the black iron oxide fe3o4 formation but the rest of the 300 series can be coated to mil dtl 13924 link is to free spec at defense logistics agency dla mil class 4. Black oxide chemical black oxidizing. Black oxide rohs compliant.
