Q355GNH weathering steel is a kind of atmospheric corrosion resistant steel, which has better corrosion resistance than A283 Gr D mild steel coil, 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.
DC53 mold steel has better machinability and abrasiveness than SKD11. DC53 cold work die steel A283 Gr D mild steel coil is widely used in punching die, cold work forming die, cold drawing die; forming roll, punch; precision stamping die; precision cutting die for wire cutting and punching die for various purposes; difficult to process materials Tools for plastic deformation; cold forging, deep drawing and thread rolling dies; high-speed punching punches, stainless steel punches.
Nickel element is mainly used to form and stabilize the austenite structure, so that the A283 Gr D mild steel coil steel has good mechanical properties, corrosion resistance and process performance. Molybdenum can quickly passivate stainless acid-resistant steel, and improve the corrosion resistance to solutions containing chloride ions and other non-oxidizing media. Titanium and niobium are usually used to fix the carbon in alloy steel and make it generate stable carbides to reduce the harmful effect of carbon on the corrosion resistance of alloy steel.
