Q355GNH weathering steel is a kind of atmospheric corrosion resistant steel, which has better corrosion resistance than SMA490CP corrosion resistant container steel, ordinary carbon steel by adding less alloy elements. Q355GNH weathering steel has been widely used in container, railway vehicle, bridge, building and air preheater which need to be resistant to atmospheric corrosion. Q355GNH weathering steel is characterized by the addition of less Cu, P, Cr, Ni and other alloy elements in the steel, so that a dense amorphous spinel type oxide layer with a thickness of about 50-100μm is formed between the rust layer and the base metal, which can prevent oxygen and water from penetrating into the steel matrix, slow down the development of corrosion to steel materials, and improve the atmospheric corrosion resistance.
In Nov, 2018, our Mozambique customer purchased from BBN company 500 tons carbon steel Q235B steel structure for building 10 units of gas station. We have been cooperate more than 5 years for providing plate and pipes and SMA490CP corrosion resistant container steel profile as beginning, and they are very satisfied with all the received Cargo. We extend in-house cutting, welding, grinding, bending and certification and testing of our products, on client demand. If you are interested in our steel structures or steel plate price, welcome to contact us.
Ordinary carbon steel killed steel plate deoxidizes the liquid steel before making. When the liquid steel is poured into the ingot, its reaction is relatively calm and there is no boiling state. Advantages: this kind of steel plate SMA490CP corrosion resistant container steel has no gas, less impurities, uniform stress and good welding performance. Widely used in demanding parts
As leading EN10025-6 S460QL structural steel plates supplier in China, our company has supplied hundreds of thousands tons S460QL steel plates to clients to assist them finish one after another SMA490CP corrosion resistant container steel magnificent projects.
