Deformed steel bar/When using high-strength low-alloy steel, all want the advantages of high strength and use whichever is thinner cross-section , /Medium Heavy Plate /not only in order to save weight but also for the economy as much as possible . However , we must fully consider the factors of corrosion of steel cross-section should be noted that the thinner the more corrosion . /Hot Rolled CoilsAny corrosion of steel structures are generally achieved by the method of coating the coating on properly prepared surfaces and to protect against corrosion layer. Some high strength low alloy steel has good resistance to atmospheric corrosion , which can not only enhance the effect of anti-corrosion coating , and to take appropriate preventive measures and in some cases even be in the state without the coating is exposed to the atmosphere using . Without any kind of material equally resistant to corrosion resistance might imagine conditions , low alloy high strength steel atmospheric corrosion stations and content with the group played the largest role of corrosion-resistant alloy element is changed. Improved atmospheric corrosion resistance Elemental copper , phosphorus , silicon, chromium, nickel and molybdenum.

Excellent resistance to atmospheric corrosion of some low alloy high strength steel can lead to the formation of buildings, bridges and other structures designed a new concept , namely the proper selection of these structures exposed high strength low alloy steel components to build . In the case of normal exposure to the atmosphere , exposed to atmospheric corrosion of steel in the first few months of a tight protective oxide film. Sometimes architects chosen bare steel is because they want to get a uniform appearance of atmospheric oxidation of the steel surface , and sometimes it is coated with a protective layer in order to save the economy in order to achieve the purpose . Used in the bare state of these high strength low alloy steel, the design must be considered not long steel surface is wet, but should also pay particular attention to the special atmosphere to ensure that under these conditions the corrosion rate of the steel is allowed. E.g., to enhance learning in conditions of industrial flue gas is obviously undesirable. In order to verify that you can use bare steel under certain circumstances . Atmospheric environment needs to be measured , or even need to be exposed test .
