Steel material has an irreplaceable role in many projects, especially in building construction, bridge cofferdams, road construction, foundation pit support, garden engineering, excavator paving, subgrade engineering and other projects. Therefore, the quality of A709 grade HPS100W bridge steel plate steel material can not be ignored, so how should customers identify the authenticity of steel when choosing steel materials? Today we would like to analyze it together. So that it can help you to purchase satisfied steel materials in the future.
The yield strength of Q690D steel plate is 690 Mpa and the impact temperature is - 20℃. A709 grade HPS100W bridge steel plate, Q690D steel plate has high strength, good plasticity and toughness, good weldability and good cold and hot performance. Q690D steel plate is mainly used to manufacture various large engineering structural components and construction machinery. Because of its high strength and good toughness, Q690D steel plate can reduce the self weight of components and meet the requirements of large-scale and lightweight engineering components and equipment under the condition of ensuring strength, stiffness and reliability.
Normalizing is to heat the steel parts to 30~80℃above the critical temperature for a period of time. Then the parts are taken out of the furnace and cooled in air. Since the cooling rate of normalizing is faster than that of annealing, the strength and hardness of normalized A709 grade HPS100W bridge steel plate are higher than that of annealed A709 grade HPS100W bridge steel plate, but the elimination of internal stress is not as good as annealing. The normalizing operation of A709 grade HPS100W bridge steel plate is simple, the cost is low, the productivity is high, and it is widely used in actual production.
