Detection Purpose: Check whether the chemical elements of steel valves meet the requirements

Detection range: Steel valve and its accessories

Chemical composition analysis is the metallographic analysis of chemical element composition of materials to determine the content of its constituent elements, and then analyze the performance of materials in the process of processing and use.

It is very important to analyze the chemical composition of the valve materials, and correctly sample and prepare the samples. The samples should be able to represent the batch of products they adhere to. The physical properties (structure, density, surface, etc.) and chemical composition of the samples should be relatively uniform, without oxidation, pollution, and inclusion. For different purpose valves, select the corresponding materials to ensure the quality of the valve and the performance of the long-term use process, which is not easy to crack, leak, failure and other hazards.

Steel valve has forgings and castings, and its accessories include steel plate, steel strip, steel pipe, valve rod, bolt and nut, spring material and other products.
