What are the characteristics of medium and thick plate, A709 grade 50W high strength steel? First, the performance of shock resistance and vibration is very good, so the application of medium and thick plates in buildings and bridges can greatly improve the safety. Second, the bearing capacity of medium and thick plate, A709 grade 50W high strength steel is good, the performance is excellent. The bridge, the automobile girder steel plate, and buildings have strict load-bearing requirements, and it is easy to cause accidents if the steel materials not meet the requirements, so the selection of steel is more stringent.
On March 19, 2020 the us international trade commission (ITC) vote on imports from China and India's carbon alloy A709 grade 50W high strength steel steel screw (Carbon and Alloy Steel Threaded Rod) to make a positive final anti-dumping and anti-subsidy industry damage. All five members of the international trade commission voted in favor of the ruling. The us department of commerce will issue anti-dumping and countervailing duty orders on imports of A709 grade 50W high strength steel carbon alloy steel screws from China and India, according to the itc's affirmative ruling.
Due to the rapid development of the epidemic globally, many nations have moved to a position of “social distancing” in an effort to delay the spread of the COVID-19 virus. Cases have now been detected in most countries worldwide and community spread is being detected in a growing number of countries. The World Steel Association (worldsteel) has cancelled or postponed all our upcoming membership committee meetings. In a few cases they may go ahead electronically but the majority will be reconvened at a later date.
