Introduction to 304 stainless steel head

A stainless steel head is a product used to block stainless steel pipelines. It is a product used when a pipeline reaches its end or when two heads are welded on both ends of a round pipe to form a container. Similar products include blind plates, pipe caps, plugs, etc. Other names for stainless steel heads include stainless steel non-straight edge heads, barrel body spun edges, elliptical heads, dished heads, shallow heads, various reducers spun edges, stainless steel reducers spun edges, flat bottoms, hemispherical spun edges, spherical heads, etc.

The magnitude of structural stress in stainless steel heads is related to factors such as the cooling rate, shape, and chemical composition of the material in the martensitic transformation zone. The ultimate result of changes in structural stress in stainless steel heads is tensile stress on the surface and compressive stress in the core, which is exactly the opposite of thermal stress. Practice has proven that during heat treatment, any workpiece will experience both thermal stress and structural stress as long as there is phase transformation. However, thermal stress is generated before structural transformation, while structural stress is generated during the structural transformation process. The combined effect of thermal stress and structural stress throughout the cooling process is the actual stress present in the workpiece.
