The surface treatment of VAN’s bicycle parking racks are powder coating,stainless steel and galavnized. Powder coating as a rust prevention measure, it also has a beautiful appearance and protects the bike rack to be used outdoors for more than 5 years. Through galvanizing as an anti-rust measure, the outdoor bike racks can be protected from normal use for more than 5 years. Stainless steel materials can effectively prevent corrosion and rust. Through polishing and brushing, the surface of the bike rack is smoother and more beautiful.
Stainless Steel (Stainless Steel) according to GB/T20878-2007 definition is Stainless, corrosion resistance as the main characteristics, and chromium content is at least 10.5%, the maximum carbon content is not more than 1.2% of Steel.
Stainless steel processing technology refers to the performance of stainless steel shear, folding, bending, welding and other mechanical processing of the final industrial production required stainless steel products, in the process of stainless steel processing with the help of a large number of machine tools, instruments, stainless steel processing equipment.
In general, the hardness of stainless steel is higher than aluminum alloy, the cost of stainless steel is higher than aluminum alloy.
Main properties are:
The requirements for welding performance are also different for different product uses. A class of tableware on welding performance generally do not require, even including some pot enterprises. But the vast majority of products require good welding performance of raw materials, such as second-class tableware, thermos cups, steel pipes, water heaters, drinking machines and so on.
The vast majority of stainless steel products for corrosion resistant performance is good, like a, 2 kinds of tableware, kitchen utensils and appliances, water heaters, water dispensers, etc., some foreign businessmen on corrosion resistance of products also do experiment: in NACL aqueous solution heated to boiling, after a period of time out solution, wash and drying, weight loss, to determine the degree of corrosion (note: When the product is polished, Fe content in the emery cloth or sandpaper will lead to rust spots on the surface of the test.)
Stainless steel products in today's society are generally polished when the production of this process, only a few products such as water heater, water dispener liner, do not need to be polished. So this requires that the polishing performance of raw materials is very good.
Heat resistance refers to the high temperature stainless steel can still maintain its excellent physical and mechanical properties.
When the amount of chromium atom in steel is not less than 12.5%, the electrode potential of steel will change from negative potential to positive electrode potential. Prevent electrochemical corrosion.
