    ASTM A500/A500M-21a test method covers the structural tubing and the use of cold-formed welded carbon and alloy steel tubing in it. The process proceeds with the quality check, heat treatment, and the testing chemical composition of materials. The results obtained from this method help in quality control, research, and performance evaluation of structural tubing. The use of Carbon steel alloys for constructing bridges and buildings is specified.  


    The specimen is manufactured as per the specified measurements, and limits are selected for the chemical composition of the material. The electric furnace or elemental oxygen makes steel, whereas a seamless welding process makes tubing. The analysis is done following the agreement between the purchaser and the producer. Tensile strength is measured, and heat treatment is applied. Then, a stress-corrosion resistance test is performed, and various alloys’ cracking capabilities are tested. The flattening test and the tension test are performed. The method also covers the packaging and certification. 

    Specimen Size:

    Specimen size should be as per the requirements. In this case, the periphery of the specimen should be 88 inches or less, and thickness should be 1.0000 inches or less.


    The method covers the certification, sampling, testing, and specimen inspection within the set limits. The heat treatment is applied to grade D materials. 


    THE ASTM A500/500M-21a test method is specifically essential for structural tubing quality assurance and durability. In this regard, the top service provider is the Infinita Lab, which ensures efficient and reliable testing.
