Stainless Steel Has a Unique Strength, High Wear Resistance

Stainless steel has a unique strength, high wear resistance, excellent anti-corrosion properties, not easy to rust and other properties. It is widely used in chemical industry, food machinery, mechanical and electrical industry, environmental protection industry, household electrical appliances industry and family decoration. It gives people a feeling of luxuriant nobility. The application prospects of stainless steel will be more and more widely, but this determined by stainless steel surface treatment technology. Commonly used stainless steel pipe surface treatment technology has the following methods: 1. Surface color bleaching treatment; 2. Mirror-bright surface treatment; 3. Surface shading. Surface color bleaching treatment: Stainless steel in the process, after the coil, bar-side, welding or heat treatment, it will generate a black oxide. This hard gray-black oxide is make up with NiCr2O4 and NiF, it general remove by hydrofluoric acid and nitric acid in the past. This method cost is large, polluting the environment, harmful to human and strong corrosive, so it is eliminated gradually. Mirror-bright surface treatment: According to the complexity of stainless steel product and user requirements, it can apply mechanical polishing, chemical polishing, electrochemical polishing and other methods to achieve the mirror surface gloss. Surface shading: Stainless steel coloration not only gives stainless steel products all sorts of color and increase product varieties, but also improves the product wear resistance and corrosion resistance. Stainless steel coloration methods are summarized as follows: 1. Chemical oxidation coloring method; 2. Electrochemical oxidation coloring method; 3. Ion deposition oxide coloring method; 4. Oxidation coloring method; 5. Gas cracker coloring method. Selecting a suitable for processing to treat stainless steel surface should according to the product structure, material, and the different requirements of surface. Source: al-metal.org
