Why heat treatment of stainless steel wire mesh?
Stainless steel wire mesh has always been loved by people, and its corrosion resistance is particularly valued. The stainless steel wire mesh surface is smooth and bright, will not rust, and can withstand the weather. Therefore, such a good product must be specially treated, and the stainless steel wire mesh has its characteristics after heat treatment.
Stainless steel wire mesh heat treatment technology is also a key link in the entire production process of stainless steel mesh. After the explosion welding, the strength and hardness of the stainless steel mesh increase. The plasticity is reduced, which is not conducive to subsequent straightening and application requirements.
The actual process of heat treatment of stainless steel wire mesh is to eliminate the internal stress after the explosion composite. Improve plasticity. However, since ordinary stainless steel has its own solution treatment system, it is inevitable to conflict with the heat treatment system of carbon steel, such as ultra-low carbon dual phase 00Cr18Ni5M. Fe-Cr intermetallic brittle phases such as 3512 and 00Cr22Ni5M03N tend to precipitate after a long period of time below 950Y, which will seriously deteriorate the plasticity and intergranular corrosion resistance of stainless steel. The standardized temperature of carbon structural steel is about 890Y. Overheating over a long period of time can result in coarse particles and reduced toughness.
This combination is particularly important in selecting heat treatment temperatures, holding times and cooling systems. In addition, the heat treatment method also has a great influence on the shear strength of the stainless steel mesh. Taking the 1Cr18Ni8T1 + 16Mn stainless steel mesh as an example, when the heat treatment temperature is higher than 400 degrees, the shear strength of the matrix is significantly reduced due to the coarse particles in the matrix, but the impact toughness, bending properties and elongation with impact toughness, bending properties and elongation The rate of increase increases. Heat treatment temperature. Great progress.
What are the common causes of damage to stainless steel wire mesh?
Stainless steel wire mesh, like its name, can be interpreted as stainless steel that does not rust. In fact, this is just a consensus in everyone's life. Strictly speaking, this material of stainless steel will be destroyed and rusted to some extent. As a derivative, the stainless steel wire mesh will also rust. So what are the common types of stainless steel screen damage? Let's understand together.
Stainless steel wire mesh wear is a common damage to stainless steel wire mesh, which is half the problem and can still be used.
The deformation of the stainless steel wire mesh is deformed, which will greatly affect the causal relationship. Because the deformation changes the length and pattern of the stainless steel screen.
Stainless steel wire mesh broken wire is usually the result of deformation of the stainless steel wire mesh to a certain extent. This is an early appearance of broken wires when the stainless steel mesh is deformed with rust. This time we should replace the damaged stainless steel screen as soon as possible.
Stainless steel wire mesh multi-layer wound stainless steel wire mesh is usually made by winding on the top of the drum. Sometimes, due to improper operation, the stainless steel wire mesh may be wound on the top of the drum. This time, the winding wire will be seriously deformed and cannot be used.
These are the common types of damage to stainless steel screens. If you are careful, we must find that these common damaged stainless steel screens can be avoided. For example, we can use stainless steel wire mesh to lubricate and prevent it from rusting. In the production process, be careful not to entangle the layers on the drum to avoid deformation of the stainless steel mesh.
The above is the relevant content of stainless steel wire mesh, I hope to be helpful to everyone.
