Ingredients stainless steel wire stainless steel wire oxide scales are contained in the multi-Cr2O3 and spinel FeO # Cr2O3 stainless steel wire, usually black, sometimes blue or green, as the axis, such as octahedral crystal, glass, shiny, shell-shaped cross-section the density of 350 ~ 5121t / m3, melting point up to 2435e, not soluble in H2SO4, Cl or HNO3 1H inorganic acids such as the hardness of 715 ~ 185,800e time. Using only a single hydrochloric acid or sulfuric acid is difficult to remove the scale. It is generally mixed acid wash, one of the strong acid from oxidation, and the other (usually HF) from activation. Stronger oxidant is, in its discharge while reducing the oxidation of the trivalent chromium high chromium; activation is the halogen ion as an activator is added to the pickling solution, such as F- ions, they can replace the oxygen in the oxide scale, change the structure of the scale, it soluble in acid. Two stainless steel wire coiled stainless steel wire process is processing a variety of standard parts, machinery shaft parts, cold-drawn steel and metal products in the main material. In the United States, Japan and other countries in the production of stainless steel wire about 8% to 9%. Stainless steel and heat treatment in the process of forming a soft stainless steel wire, the surface will produce a layer of black oxide of stainless steel wire, such a dense oxide structure, and the substrate adhesion That good stainless steel wire, comprising Fe, Cr, Ni, small amounts of C and Si, there may Mn, Ti, Mo and W and other elements, oxides structure: ferrous oxide (FeO), iron oxide (Fe2O3), iron oxide (Fe3O4), chromium oxide (Cr2O3), nickel oxide ( NiO), silica (SiO2), chromium spinel (Cr2O3 # FeO), and nickel spinel (Ni # Fe2O3) and the like. Stainless steel oxide destroys the appearance of the steel surface, will accelerate the electrochemical corrosion of metal surfaces, and the existence of surface stress will accelerate the stress corrosion steel surface. Therefore, the stainless steel surface oxide must be removed prior to subsequent processing and clean.
