Stainless steel products in our daily lives are more common, such as: stainless steel staircase handrail, which is that we are exposed to, stainless steel rails, a large shopping mall which is also very common, stainless steel door handles, etc., then what is stainless steel it, and what the advantages and disadvantages and properties of stainless steel, stainless steel classification is how to divide it? Read Shing Decoration Group of professional engineers to explain to you this question. As the name suggests, is not easy to rust stainless steel, some stainless steel, are both of a stainless steel, and also acid resistance (both corrosion resistance). Why stainless steel will have characteristics of it, which is derived from a film on stainless steel surfaces caused. On the surface of stainless steel chromium-rich oxide film (ie passivation film), completely isolated the oxygen in the air, thereby protecting the substrate from oxidation corrosion inside. But experiments show that stainless steel and corrosion resistance is relative, when the steel in the atmosphere, water and other weak medium and nitric acid oxidation medium, with the steel corrosion resistance of chromium in the water content increases increase, when the chromium content reaches a certain percentage, the steel corrosion resistance mutation, that is rusty from easy to rust, never corrosion resistant to corrosion. There are many classifications of stainless steel. If classified according to chemical composition, it can be divided into chromium stainless steel and chrome-nickel stainless steel and other two systems. If you press the corrosion type points, it can be divided into resistance to pitting corrosion of stainless steel, stress corrosion of stainless steel, resistance to intergranular corrosion of stainless steel. If you press the classification and organization structure at room temperature, but can be martensitic, austenitic, ferritic and duplex stainless steel type. Then by purpose to points, there are nitric acid-resistant stainless steel, acid-resistant stainless steel, water-resistant stainless steel and so on. By Features classification can be divided into non-magnetic stainless steel, free cutting steel, cold steel, high strength stainless steel and so on. Classified according to various characteristics of the product, you can easily distinguish each type of stainless steel applies range of products, which also makes us relevant in the selection of stainless steel products, with the reference point, more clearly, quickly pick a greater demand for my product. Because stainless steel has excellent corrosion resistance, good formability, compatibility and a wide temperature range, strength and toughness, and other characteristics, so make stainless steel in heavy industry, light industry, household goods industry and building decoration industry wide range of applications. Read Shing Decoration Group production of stainless steel staircase handrail, guardrail and other products, good quality stainless steel followed, making the company's products, but also has good resistance to corrosion, rust and other characteristics. We will be professional attitude, for new and old customers to provide the best quality service! Welcome customers to inquire negotiate!
