Titanium Plate Stainless Steel Caps are a type of stainless steel caps, primarily used for sealing stainless steel pipes. During their manufacturing process, there is a critical procedure that requires utmost caution: the heat treatment process. When heat treating titanium plate stainless steel caps, it is easy to encounter thermal stress, as the cooling speed and time of the surface and core are inconsistent during the heating and cooling process, resulting in temperature differences.
Additionally, it is more prone to organizational stress, primarily due to the change in structure, i.e., the transformation from austenite to martensite, where an increase in specific volume leads to the expansion of the workpiece. This results in a sequential phase change across different parts of the workpiece, causing inconsistent growth in volume.
During the heat treatment of titanium plate stainless steel caps, both thermal stresses and structural stresses are generated. Regardless of whether they cancel each other out or add up, one will dominate. When thermal stress prevails, the result is tensile forces in the core of the workpiece and compressive forces on the surface. When structural stress prevails, the result is compressive forces in the core and tensile forces on the surface.
The general production process for titanium plate stainless steel hemispheres includes material feeding, physical and chemical treatment, material cutting, hot forging of the product, and heat treatment of the product. The typical inspection steps are product inspection, product finishing, inspection of finished hemispheres, labeling, re-inspection of semi-finished products, and re-labeling. The packaging steps involve printing before packaging and then shipping.
