w shape structural steel w16x89 w16x100 beam
W16x89 h section steel: the section height is about 406mm, the flange width is 254mm, the web thickness is 12.7mm, the flange thickness is 20.6mm, and the weight per meter is about 132.5kg.
W16x100 h beam: According to the American standard H-beam size rule, the section height is about 410mm, the flange width is about 260mm, the web thickness is about 14mm, the flange thickness is about 23mm, and the weight per meter is about 149kg.
W16x89 W16x100 h beam steel structure is often used in building structures with high requirements for strength and stability, such as key supporting structures of large commercial buildings, industrial plants, and high-rise buildings; in bridge construction, it can be used to build beams, piers and other structural components of large-span bridges; it is also suitable for the brackets and foundation structures of some large mechanical equipment, as well as the structures of lifting and transportation equipment that need to bear large loads.
What are the changes in the mechanical properties of American standard H-beam W16x89 and W16x100 at different temperatures?
The material of American standard H-beam W16x89 and W16x100 h beam is usually A572GR50.
Low temperature environment
Strength: At low temperature, the yield strength and tensile strength of A572GR50 h section steel will be improved.
Toughness: A572GR50 has good low temperature toughness. In the temperature range from room temperature to - 20℃ or even lower, it can usually still maintain good toughness and can withstand a certain degree of impact load without brittle failure.
High temperature environment
Strength: As the temperature increases, the yield strength and tensile strength of A572GR50 structural steel h beam will gradually decrease.
Toughness: At high temperature, the toughness of the steel will usually increase, the material will become softer, and the elongation will increase.
Normal temperature environment
At normal temperature, W16x89 and W16x100 h type beams made of A572GR50 have good comprehensive mechanical properties, with a yield strength of no less than 345MPa, a tensile strength between 490 and 600MPa, and an elongation of ≥22% to 35%. They can withstand large loads and a certain degree of deformation without breaking, and have good impact toughness, which can meet the use requirements of most conventional engineering structures.
