(1) Inspection Method:
The tensile test is one of the most commonly used methods for evaluating material properties. Standard procedures include GB/T 228-87, JIS Z2201, JIS Z2241, ASTM A370, GOST 1497, BS 18, and DIN 50145. These standards define the process for measuring mechanical properties under tension. Another important method is the bending test, which is widely applied to assess the ductility and flexibility of materials. Commonly accepted standards for this test are GB/T 232-88, JIS Z2204, JIS Z2248, ASTM E290, GOST 14019, and DIN 50111. Each standard provides guidelines on how to perform the test and interpret the results.
(2) Performance Index:
When evaluating the performance of angle steel, key tests include tensile and bending tests. The main indicators measured during these tests are yield strength, tensile strength, elongation, and the ability to withstand bending without cracking. These parameters help determine the material’s suitability for different structural applications. Proper testing ensures that the steel meets required quality and safety standards before being used in construction or manufacturing.
