Mechanical properties of angle steel
(1) Inspection method:
① Tensile test method. Common standard inspection methods include GB/T228-87, JISZ2201, JISZ2241, ASTM A370 ГОСТ 1497, BS18, DIN50145, etc;
② Bend test method. Common standard inspection methods include GB/T232-88, JISZ2204, JISZ2248, ASTM E290 ГОСТ 14,019, DIN50,111, etc.
(2) Performance index: the inspection items for evaluating the performance of angle steel are mainly tensile test and bending test. The indicators include yield point, tensile strength, elongation and bending qualification.
