Ensuring stability and performance in extreme environments Haihao Group’s advanced heat treatment process for flanges
When it comes to operating in extreme temperatures ranging from -40 degrees Celsius to -120 degrees Celsius, Haihao Group understands the critical importance of ensuring the stability and performance of our flanges. To meet the demands of such challenging environments, we employ a meticulous heat treatment process that enhances the durability and resilience of our products.
At Haihao Group, our heat treatment process is specifically tailored to optimize the material properties of our flanges, allowing them to withstand extreme temperatures without compromising their structural integrity. Let’s delve into the details of this advanced process:
Annealing: The first step in our heat treatment process is annealing, where the flanges are heated to a specific temperature, typically around 850 to 900 degrees Celsius, and then slowly cooled. This process relieves internal stress and enhances the material’s ductility, making it more resistant to thermal expansion and contraction.
Normalizing: After annealing, the flanges undergo a normalizing treatment. This involves heating the material to a temperature between 900 and 950 degrees Celsius and then allowing it to cool in still air. Normalizing refines the microstructure of the flanges, promoting uniformity and improving their mechanical properties, including strength and toughness.

Quenching and Tempering: To further enhance the flanges’ ability to withstand extreme temperatures, we employ quenching and tempering techniques. Quenching involves rapidly cooling the flanges in a controlled manner, typically using water or oil, from a temperature of around 920 to 950 degrees Celsius. This ensures a hardened structure. Tempering follows this process, where the flanges are reheated to a specific temperature, typically between 600 and 700 degrees Celsius, and then cooled slowly. This combination of quenching and tempering optimizes the material’s hardness and toughness, enabling it to withstand the harshest temperature conditions.
Stress Relieving: As a final step, the flanges undergo stress relieving to minimize residual stresses that may have accumulated during the heat treatment process. This typically involves heating the flanges to a temperature around 600 to 650 degrees Celsius and then gradually cooling them. This ensures dimensional stability and helps prevent deformation or failure under extreme temperature fluctuations.
The use of our advanced heat treatment process provides several significant benefits for our flanges operating in extreme temperature environments:
Enhanced Strength and Durability: The carefully controlled heat treatment process optimizes the material’s mechanical properties, improving strength and durability. Our flanges can withstand thermal stresses and maintain their structural integrity even in the most challenging temperature ranges.
Reduced Risk of Brittle Fracture: By precisely controlling the heat treatment parameters, we minimize the risk of brittle fracture, which can occur under low-temperature conditions. This ensures the reliability and safety of our flanges in extreme environments.
