Selection and Application of Steel Plate Material

Material Classification Steel Characteristics Typical Use Grade Examples Pipeline steel Low carbon content, low carbon equivalent, high purity and low impurity content, fine all around mechanical properties, low temperature toughness and welding property. Spiral welded pipe for petroleum and natural gas long-distant transportation. X60,X70, S360 X60RL Cold Forming Steel Enough ductility to bend 180° in any directions, suitable for simple forming, bending and welding machining to manufacture parts do not require much on appearance Common machined parts such as gear, electric instrumentation box, hydraulic jack casing, etc. SPHC DD11(StW22) Cold Forming Steel A better ductility than common grade and thus fit for machined parts through drawing or relatively complicated deformation. Bicyclesâ�� collapsible, wheel rim and wheel disks, etc. SPHD DD12(StW23) Cold Forming Steel With better ductility than drawing grade and a better and even performance, this material can be used in manufacturing machined parts through deep drawing or complicated and drastic deformation. Automobileâ��s bumper, compressor unit, oil filter box, etc. SPHE DD13(StW24) Structural Steel Guaranteed mechanical properties (strength, elongation, impact tenacity, etc.) and process performance(bending),fine welding property, fit for simply machined welded or riveted structures Building structure, bridge, ships, railway vehicles, pipeline machines and other structure units SS400 St37-2 St52-3 Automobile Structure Steel Similar to structural steel in properties, and besides strength also requires a better elongation etc., to ensure fine machining-forming properties, more strict in surface quality and dimension accuracy. Automobiles girder, beam, wheel, chassis components APH370 QstE420TM B510L Corrosion Resistant Structure Steel Beside the strength properties of above-mentioned structural steel, it is also provided with fine atmosphere or sulphuric acid or seawater corrosion resistance property. Oil well platform, sea harbour buildings, oil extraction platforms, ships, vehicles, chemical and oil vessels for corrosive media B480GNQR NAW400 B490NQR S-TEN2 (S-ten2) MARILOYS490A (Mariloy S50A) Mechanical Structure Steel Similar to structural steel, and besides strength also with requirement on toughness and wear ability to fit for machinery and tool manufacturing. Chains, binder, gardening tools S20C C35 Welded gas vessel pressure vessel steel Apart from fine mechanical properties, weld ability and machining properties, there are strict requirements on plate material, thickness evenness, and steel quality to ensure a safe and reliable service under high pressure.
