Spring steel refers to the special alloy steel used to manufacture all kinds of springs and other elastic elements. hot sale 09CuPCrNi-A steel, Spring steel has excellent comprehensive performance, good surface quality, accurate shape and size. Spring steel has hot rolled steel, cold drawn steel, cold rolled steel strip and so on. How much a ton of spring steel is related to the grade of spring steel, the market situation and the manufacturer.

Fatigue wear often occurs on the rolling or rolling and sliding friction surface of the wear-resistant plate, hot sale 09CuPCrNi-A steel. Under the action of alternating stress, the soft area of the surface will produce plastic deformation. When the stress exceeds the tensile strength of the material, cracks will appear in the weak places, and the cracks will continue to expand under the effect of stress. When the crack length reaches a certain value, it will cause fracture and cause the phenomenon of pitting and spalling.
