hardox 450 specification ERW pipe OD rand(21.3,660 mm

Good Hardox 450 specification welding performance: Linepipe assemble is usually in the wild environment with fierce conditions, welding performance is one basic requirement for wild welding work. Corrosion resistant: gas or fluid transmitted in Hardox 450 specification pipelines may contain corrosive elements-S. Good moldability: for cold roll forming process is taken place before welding, good moldablity is the key to good ductility and toughness of final product.As to the Chemical composition, the different content is a main on carbon content, while the carbon content of Hardox 450 specification, A283Gr. D is no more than 0.27% and it is higher than Grade C (≤0.24%) ; as to the mechanical property, the differences are tensile strength and yield strength, while the tensile strength of ASTM A283 Gr.D is 415-550MPa (60-80 ksi) and yield strength of ASTM A283 Grade D is 230MPa (33 ksi).In the process of Hardox 450 specification steel transportation, enterprises often use railway transportation, highway transportation, water transportation and other ways to transport.
