PRODUCT DETAILS

Other names of stainless steel head: stainless steel head without straight edge, barrel swivel edge, elliptical head, disk-shaped head, shallow-shaped head, all kinds of head swivel edge, stainless steel head swivel edge, flat bottom, hemispherical swivel edge, spherical head and so on.

The size of the organization stress of stainless steel head is related to the cooling speed of workpiece in martensitic phase change area, shape, chemical composition of material and other factors. Stainless steel head organization stress change is the result of the surface layer by tensile stress, the heart by compressive stress, just the opposite of thermal stress. Practice has proved that any workpiece in the heat treatment process, as long as there is a phase change, thermal stress and tissue stress will occur. Only thermal stress in the tissue transformation has been produced before the stainless steel head, and tissue stress is produced in the process of tissue transformation, in the entire cooling process, thermal stress and tissue stress combined effect of the results, is the actual existence of stress in the workpiece.
