What are the advantages of forgings and why should forgings be selected?

What are the advantages of forgings and why should forgings be selected?

Dalian forgings are widely used in building materials industry. Conceptually, a forging is a metal that exerts pressure to create a desired shape or appropriate compression through plastic deformation.

Rescue measures for loose connection between stainless steel piston rod and piston

Rescue measures for loose connection between stainless steel piston rod and piston

Before the use of the hydraulic cylinder, the stainless steel piston rod and piston must be connected. During the use, due to some reasons, the stainless steel piston rod and piston may become loose.

What are the advantages of forging heat quenching of Dalian forgings?

What are the advantages of forging heat quenching of Dalian forgings?

Dalian forging heat quenching can improve the properties of forgings.

Forging heat quenching can significantly improve the strength and hardness on the premise of maintaining plasticity and toughness.

Four stages of tempering of forgings in Dalian

Four stages of tempering of forgings in Dalian

With the increase of tempering temperature, the quenching structure of Dalian forgings will change a series. According to the structure transformation, tempering is generally divided into four stages: martensite decomposition, residual austenite decomposition, carbide transformation, carbide aggregation and growth and ferrite recrystallization.

Problems needing attention in forging process

Problems needing attention in forging process

Forging is a very important step in steel manufacturing. A good steel worker must have a good forging skill. The forging process needs to be exposed to some high-temperature processes, so we should pay attention to some problems in forging and should not ignore these small details.

Rare causes and treatment of overheating of piston rod

Rare causes and treatment of overheating of piston rod

Rare reasons for overheating of piston rod:

1. The appearance of the piston rod is too detailed.

2. Sundries are mixed in the gas and oil in the filling and evaluation.
