What is the difference between ut and x-ray pipe examination
The use of ultrasonic testing methods is to detect instrument called the ultrasonic flaw detector. Its principle is: the ultrasonic wave propagation in the material is detected, the acoustic properties of the material and the internal organization changes have some impact on the propagation of ul...Read more -
Zinc coating
Zinc is a metallurgical reaction process. From the microscopic point of view, the process of hot dip galvanizing is two dynamic balance, heat balance and zinc iron exchange equilibrium. When the steel workpiece immersed in about 450 ℃ molten zinc liquid, room temperature liquid zinc absorption he...Read more -
Advantages and disadvantages of hot rolled steel
Hot rolled is relative to the terms of the cold-rolled, cold-rolled is in the recrystallization temperature below the rolling, and the hot rolling is carried out at above the recrystallization temperature rolling. Advantages: hot rolled can damage the cast microstructure of the steel ingot, refin...Read more -
