Test method for Angle steel quality

Angle steel quality inspection method

1. Angle steel appearance quality inspection: The surface quality of Angle steel is specified in the Angle steel use standard, and there are generally no delamination, cracks, cracks and obvious problems in the steel. In the steel use standard also specifies the allowable range of Angle steel geometric shape deviation, generally including bending degree, side width, side thickness, top Angle, weight and other requirements, and stipulates that the Angle steel must not have obvious torsion.

2. Mechanical properties test: the use of tensile test method and bending test method, mainly to test the properties of Angle steel, the use of tensile test and bending test. The index includes the weakness of the Angle steel, tensile strength, elongation and qualified bending.
