Bluing steel strap is to heat treatment the steels at about 200 degree centigrade and make the steel surface to form a layer of dense ferroferric oxide film. Its main ingredient is ferroferric oxide.
The layer of protective film can prevent iron rusts, before packing, you also can paint a layer of anti-rust oil to prolong the store time.(Dense ferroferric oxide film can film the steel body isolated from air and water, and have the effect of anti rust) In general, they are 3-4 layer of packaging, or we can according to customer requirements for packaging.
