S355J0 686x254x140 686x254x152 Structural Steel Universal Beam
Material characteristics of S355J0 h steel profile
Chemical composition: C≤0.22%, Si≤0.55%, Mn≤1.60%, P≤0.025%, S≤0.025%. Carbon can enhance the strength and NMness of steel, silicon and manganese can improve strength and toughness, phosphorus and sulfur are impurity elements that need to be strictly controlled, and it also contains a small amount of alloy elements such as chromium, nickel, copper, etc., which can improve corrosion resistance, fatigue resistance and other properties.
Mechanical properties: yield strength is 355MPa, tensile strength is between 470-630MPa, and elongation reaches 22%. At the same time, it has good impact toughness, processing performance and fatigue resistance, and can adapt to various complex working conditions.
Specifications of UB H-shaped steel
UB 686x254x140 steel h profile: height is 686mm, flange width is 254mm, and theoretical weight per meter is 140kg.
UB 686x254x152 h beam section: 686mm in height, 254mm in flange width, 152kg in theoretical weight per meter.
Usually produced by hot rolling process, the steel is heated at high temperature and subjected to strong plastic deformation in the rolling mill to obtain the required cross-sectional shape and size. In some cases, normalizing treatment may be performed, and after heating to a certain temperature, it is naturally cooled in the air to eliminate internal stress and improve organizational properties.
Application areas of S355J0 UB 686x254x140/152 h steel profile
Construction engineering: It can be used to build frame structures, support structures and roof structures of high-rise buildings, commercial buildings, industrial plants and residential buildings, and can withstand large loads.
Bridge construction: It can be used to manufacture structural components such as main beams, secondary beams, piers and abutments of bridges, which can withstand the weight of the bridge itself, vehicle loads, and natural forces such as wind and earthquakes.
Mechanical manufacturing: It can be used to manufacture large equipment frames, mechanical workbenches, etc., to provide solid support for the equipment and ensure that the equipment can withstand various forces during operation.
Power engineering: It is a common material for structures such as transmission towers and substation frames. It can withstand the weight of wires, wind loads, and ice loads, etc., to ensure the safe and stable operation of transmission lines and substations.
