Lifting tongs are small tools that use the clamping force of the jaws to clamp the steel plate and lift it up and down. Because it needs to be in frequent contact with the steel plate, it has high quality requirements. Therefore, special attention should be paid to its processing results in the production and processing link.

Heat treatment is an inevitable process for all steel materials. The purpose is to enhance the hardness of lifting tongs, improve its plasticity, and enhance its wear resistance. Generally, after heat treatment, the hardness of a lifting tong can reach HRC60 or above. Although heat treatment has greatly improved its hardness, strength, and wear resistance, in the actual industrial production process, the hoisting tongs that have undergone heat treatment will be oxidized and decarburized, which is caused by high temperature heating, which is generally unavoidable. It will also become thinner, invisible to the naked eye, and likely to degrade the performance quality of the lifting tongs.

As a manufacturer of steel plate lifting tongs, we pay great attention to product quality. In view of this situation, we will consider the steel plate in advance and make corresponding thickness compensation to ensure that the thickness of the steel plate meets the specified standard, and we will leave enough processing allowance or Applying anti-oxidation coating can prolong its service life to a great extent.
