Acid pickling, phosphating, passivation, and saponification of seamless steel pipes
The pickling and passivation of seamless steel pipes is a chemical reaction. Firstly, the oxide skin and rust on the steel surface can be removed through the pickling solution, while completing the passivation process. It can effectively prevent oxidation of seamless steel pipes and achieve the ...Read more -
Introduction to Steel Mechanical Properties
Yield point When the stress of a steel or specimen exceeds the elastic limit during stretching, even if the stress no longer increases, the steel or specimen continues to undergo significant plastic deformation, which is called yield. The minimum stress value at which yield occurs is the ...Read more -
