Commonly used materials for square steel tubing end caps, because end caps have to withstand impact loads during work, in order to enhance strength and impact toughness, and obtain fiber structure, cast iron casting is often used.
Castings are used for the blanks. The material is mostly gray cast iron ht200, which has the advantages of easy deformation, good vibration absorption, strong wear resistance and good machinability. And then after machining the final
Obtain the finished end cap. In addition, after casting, in order to eliminate residual stress, personnel should be arranged.
Time efficiency treatment. If a single piece is produced in small batches, the blank type of section steel should be used for blanking.
