Q690D carbon steel material,Galvanized sheet refers to the steel plate with a layer of zinc on its surface. Galvanizing is an economic and effective anticorrosion method of steel plate. Galvanized sheet can be divided into hot galvanized sheet and electro galvanized sheet according to production process. The zinc layer of hot-dip galvanized sheet is thick, which is used for parts with strong corrosion resistance The thickness of zinc layer of galvanized sheet is thin and even, which is mostly used for painting or indoor products,Q690D carbon steel material.

In January, 2019, our South Africa customer purchased 669 tons S235J2+N carbon steel plates to use in their tank fabrication project . S235J2 steel, as a non-alloy structural steel grade, is mainly used in structural projects and tanks. J2 symbol -20 temperature impact test. The client required CEV 0.38%, S≤0.01%, 100% UT, Charpy V-notch impact test at-20℃, Z25 for S235J2+N plates. After they receiving the S235J2+N steel plates, the customer are very satisfied with the quality of this batch of products.

AR400 wear resistant steel is a special structural steel with high wear resistance. Generally speaking, the higher the hardness, the higher the wear resistance of the steel, . The average hardness of AR400 wear-resistant special structural steel is 400HB. After quenching, AR400 wear resistant steel has good martensite bainite microstructure. The addition of Molybdenum (Mo), Nickel (Ni) and Boron (B) alloys ensures uniform texture in the whole thickness direction of AR400 wear resistant steel.
