We have a very ASTM A283 grc steel plate extensive commodity information network, with partners all over the world, and have become the full authority of many European and American traders in China. Under the guidance of the business philosophy of "creating the best service" and through the unremitting efforts of all employees, we have achieved remarkable results.
ASTM A283 grc steel plate, S690Q plate is used to manufacture low-temperature resistant, high-strength key components, construction machinery, mining machinery structures, etc. It is a high-strength structural steel plate. S690Q mechanical performance analysis: The thickness of S690Q is 8mm-50mm, the yield strength is not less than 690, the tensile strength is 770-940, and the elongation is not less than 14. The thickness of S690Q is 50mm-100mm, the yield strength is not less than 650, the tensile strength is 760-930, and the elongation is not less than 14. S690Q thickness is 100mm-150mm, yield strength is not less than 630, tensile strength is 710-900, elongation is not less than 14.
First of all, the metallurgical quality of a good ASTM A283 grc steel plate is good, and its surface quality is also good. There can be no surface defects or decarburization. In addition, it also needs to have accurate overall dimensions, because it is related to the accuracy of the workpiece, so its data gap cannot be too large.
