→ISO15630-3 Steel for the reinforcement and prestressing of concrete-Test methods-Part 3: Prestressing steel
→Six steel specimens are used for stress corrosion tests to determine the time taken for steel to be immersed in a thiocyanate solution at a given constant temperature at a constant tension until fracture.HRJ Tester rigid rack Tester, load acting on the horizontal direction of the closed frame.The time measuring device has a resolution of 0.01h, which can automatically control, stop, keep and record the fracture time with an accuracy of ±0.1h.HRJ Tester;Cylindrical solution corrosion container, imported container material resistance to high temperature, corrosion resistance, closed at both ends, no leakage, ensure no air into.The diameter of the sample is ≤19mm, the inner diameter of the test vessel is > 70mm, the diameter of the test vessel is 19 < d≤50mm, and the inner diameter of the test vessel is > 100mm.
