Why is the stainless steel water divider subjected to brazing heat treatment

The main purpose of conducting brazing heat treatment on the stainless steel water divider is to optimize the joint performance, eliminate residual stress, improve the microstructure, and enhance the overall strength and corrosion resistance, thereby ensuring its safety and reliability during use. The following is a detailed explanation of these reasons:

Optimizing joint performance: During brazing, the brazing filler material melts and fills the gap between the joint, forming a strong connection. However, the performance of brazed joints may be affected by various factors such as the selection of brazing filler material, brazing temperature, and holding time. Through brazing heat treatment, the microstructure of the joint can be further adjusted, eliminating brittle phases and improving the strength and toughness of the joint.

Eliminating residual stress: During brazing, due to the non-uniformity of heating and cooling, the joint area may generate residual stress. These residual stresses may cause cracks or failures in the joint during use. Brazing heat treatment can eliminate or reduce residual stress through heating, holding, and cooling steps.

Improving microstructure: Brazing heat treatment can change the microstructure of the joint area, making it more dense and uniform. This helps improve the corrosion resistance and oxidation resistance of the joint, thereby extending the service life of the stainless steel water divider.

Enhancing overall strength: Through brazing heat treatment, the overall structure of the stainless steel water divider can be further optimized, improving its load-bearing capacity and resistance to deformation. This is crucial for ensuring the safe operation of the water divider in high-pressure or high-temperature environments.
