What is the treatment if the stainless steel flange is directly water-cooled after being heated and forged?
Thread Content
What kind of metallographic structure and mechanical properties will the stainless steel flange get after being forged and directly water-cooled? Will the mechanical properties become better?
The stainless steel flange is directly water-cooled after forging, and its metallographic structure will undergo microstructural changes. Specifically, water cooling treatment can refine the grains and reduce holes and oxide inclusions in the structure, thereby improving the strength, hardness and toughness of the material. In addition, water cooling treatment can also reduce residual stress in the organization and improve the tensile strength and corrosion resistance of the material. Therefore, the stainless steel flange can be directly water-cooled after forging to make its metallographic structure more uniform and dense, and its mechanical properties can be improved. .
Does this mean that solution heat treatment can be omitted?
The solid solution ruler written in the photo actually requires heating, insulation and cooling during heat treatment. This is heating, forging and water cooling. I don’t know if it can replace solid solution.
There are only two requirements for solid solution treatment, as long as they are satisfied. After completion, you can check whether the effect is achieved. Use magnetism and hardness comparison, and then metallographic inspection. Two are marked with red lines.
Can you tell me what standard this is based on?
It is solid solution treatment, and the pool next to it is the solid solution treatment pool.
