The cold rolling precision bright pipe system produced by our factory has smooth appearance, uniform wall thickness, no oxide layer and high precision. The inner hole of EN10025-4 S460ML steel plate steel pipe can be divided into round, spline and plum blossom, which is widely used in automobile, motorcycle, electric power, petrochemical, ship, aerospace, bearing, pneumatic components, oil cylinder, boiler equipment, medical equipment, fitness equipment and other industries. Materials can be divided into: 10#, 20#, 35#, 45#, 40Cr, 16Mn, etc. According to the needs of users, we can make all kinds of national standard non-standard precision pipes. Special EN10025-4 S460ML steel plate materials and specifications can be ordered in advance.
Q345qC steel plate is the steel plate of bridge structure, the implementation standard is GB / T 714-2015 standard. EN10025-4 S460ML steel plate, Q345qC-Z25 steel: Q represents the yield strength, 345 represents the small yield strength, the unit is MPa, q is short for the bridge, C quality grade, corresponding to the corresponding impact temperature and impact work value, Z is the Z-direction performance that is the performance of the steel plate thickness direction, Z25 is the Z-direction Performance level requirements.
The yield point of the steel structure determines the stress that the structure can withstand without permanent deformation. The minimum yield point of typical carbon structural steel is 235MPa. The minimum yield point of typical low-alloy high-strength steel is 345MPa. Therefore, according to the proportional relationship of its yield point, the use of low-alloy high-strength steel allows the stress to be 1.4 times higher than that of carbon structural steel. Compared with EN10025-4 S460ML steel plate, carbon structural steel, the use of low-alloy high-strength steel can reduce the size of structural parts and reduce weight.
The alloying principle of low alloy high strength steel is mainly to improve the strength of steel by solid volume strengthening, fine grain strengthening and precipitation strengthening produced by alloy elements. At the same time, the effect of reducing the ductile brittle transition temperature of steel by fine grain strengthening is used to counteract the adverse effect of carbon nitride precipitation strengthening on the rise of ductile brittle transition temperature of steel, so that the EN10025-4 S460ML steel plate, low alloy high strength steel can obtain high strength while maintaining good low temperature performance.
DIN 17102 TStE285 steel plate/sheet, DIN 17102 TStE285 steel plate/sheet, under DIN standard, we can regard TStE285 steel plate/sheet as fine-grain structural steels, normalised rolled steels. EN10025-4 S460ML steel plate, DIN 17102 TStE285 is mainly used as ine-grain structural steels, normalised rolled steels. EN10025-4 S460ML steel plate, TStE285 steel plate/sheet is a hot rolled structural steels, which technical delivery conditions for normalized or normalized rolled in weldable fine grain structural steel grade. It is also regarded asEN10025:S275NL.UNE36081:AE285KT
