Test items:
1. Mechanical properties: The mechanical properties of steel bars are measured through experiments. The mechanical properties used to measure the quality standards of steel bars include yield point, tensile strength, elongation, cold bending performance, and other indicators
2. Process performance
(1) Bending performance: After bending 180 degrees according to the specified bending center diameter, the surface of the bending part of the steel bar shall not produce cracks.
(2) Reverse bending performance: According to the requirements of the purchaser, steel bars can undergo reverse bending performance tests The bending center diameter of the reverse bending test is correspondingly increased by one steel bar diameter compared to the bending test. Firstly, bend in the forward direction and then in the reverse direction. After the reverse bending test, there should be no cracks on the surface of the bending part of the steel barFunction of testing report:
