Metal Failure Analysis Services
GRG Test has accumulated many years of experience in the field of metal failure analysis and is familiar with the testing of various metal performance. Through comprehensive analysis and detection methods, we can analyze the failure causes of metal materials, which can provide scientific basis for improper design, material defects, casting defects, welding defects, heat treatment defects, etc. in scientific research and production; besides, we can also test the microstructure, mechanical properties and analyze the compositions of materials, and predict and monitor the use effect of products for you, thus providing basic basis for material selection and use.
Service Introduction
With the rapid development of industrial production, the requirements for the quality of metal components have got higher and higher, but early failure of products still occurs. Therefore, enterprises need to carry out failure analysis to find out the causes of failure, and put forward effective improvement measures to ensure the safe operation of projects. 
 

Test Cycle: 

10 to 15 working days, emergency services are available 
 

Product Scope: 

Metal-related products such as auto parts, precision components, mold manufacturing, casting, forging and welding, heat treatment and surface protection.
