  • The entire steel surface is protected, and the melted zinc is easily coated evenly, whether in the interior of the pipe fitting in a depression, or in any other corner where the coating is difficult to access. The hardness of galvanized coating is greater than that of steel. The Eta layer of the upper layer of Z is only 70 DPN hardness, so it is easy to be dented by collisions. However, the hardness values of the lower layer of Zeta layer and delta layer are 179 and 211 DPN respectively, which are higher than that of the iron material of 159 DPN. Therefore, its impact resistance and wear resistance are quite good.

  • There is no adhesion test of powder spraying or fluorocarbon spraying on packaged galvanized wire, but there are two points for reference: first, in sealed or air-free environment, non-metallic volatiles can corrode zinc coating; Second, zinc at higher than 230 degrees (c) will cause the matrix metal brittle. And powder spraying and fluorocarbon spraying are to be baked at a higher temperature and in a sealed environment, causing rapid corrosion of zinc, resulting in loose corrosion film resulting in coating adhesion decline, and even lead to (matrix) steel wire brittle situation may exist.

  • A remarkable characteristic of stainless steel wire rope is its inherent corrosion resistance to concentrated nitric acid and dilute nitric acid, which makes it easy to be distinguished from most other metals or alloys. But high carbon 420 and 440 steel in the nitric acid point test is slightly corroded, non-ferrous metal encountered concentrated nitric acid is immediately corroded, and dilute nitric acid has strong corrosion on carbon steel.
