Metal material testing
Metal material testing
It mainly involves the mechanical properties of ferrous metals, non-ferrous metals, mechanical equipment and parts. Tests and tests involving chemical composition analysis, metallographic analysis, hardness, corrosion performance, coating performance, microanalysis, fastener performance, pipe process performance, welding process evaluation and skill evaluation.
Service category
Kapoklog WSCT's excellent metal material testing laboratory provides you with a series of testing services for the material performance, process performance and safety performance of metal material products.
The testing scope of metal materials involves mechanical performance testing, chemical composition analysis, metallographic analysis, precision dimension measurement, nondestructive testing, corrosion resistance test and environmental simulation test of ferrous metals, non-ferrous metals, mechanical equipment and parts, etc.
Content of metal material test:
Test items Test introduction
Chemical composition analysis Determine the content of each element in the material to verify whether it meets the content requirements specified by the standard or the customer.
Mechanical property test Determine the mechanical characteristics of materials under various external loads (tension, compression, bending, torsion, impact, alternating stress, etc.) under different environments (temperature, medium, humidity).
Metallographic analysis Study the internal structure and defects of metals and their alloys, determine the microstructure of various alloy materials after different processing and heat treatment, and judge the quality of metal materials. Such as the quantity and distribution of various non-metallic inclusions in the structure, average grain size, etc.
Corrosion resistance test Measure the ability of the material to resist the corrosion of surrounding media, such as salt spray corrosion, intergranular corrosion, stress corrosion, etc.
Coating performance test Determine whether the quality characteristics (such as composition, thickness, firmness, etc.) of the protective layer on the surface of metal materials meet the design and use requirements of the product.
Welding performance test Determine the condition of metal materials after welding under certain process conditions, such as the possibility of cracks in the welded joint, that is, whether the crack resistance is good or bad; The reliability of welded joints in use includes the mechanical properties of joints and other special properties (heat resistance, corrosion resistance, low temperature resistance, fatigue resistance, aging resistance), etc.
Fatigue and life analysis Simulate the fatigue characteristics of materials or components under alternating load, and evaluate the life of materials.
failure analysis According to the failure mode and phenomenon, through analysis and verification, find out the cause of failure and excavate the failure mechanism. Generally, it includes background information collection, field investigation, laboratory testing, result analysis and conclusion.
Nondestructive testing On the premise of not damaging the working state of the workpiece or raw materials, check the surface and internal quality of the inspected parts, such as rt/ut/mt/pt/ct, etc.
Precise dimension measurement
Use precision measuring equipment to test and analyze the size, shape and trajectory of parts or components.
