Metal composition analysis and testing standards are the key basis for ensuring the quality, performance and safety of metal materials. These standards usually cover the test methods and requirements for chemical composition, physical properties, mechanical properties and microstructure of metal materials. The following are some of the main aspects of metal composition analysis and testing standards:
1. Chemical composition analysis standards
Chemical composition analysis is the core part of metal composition analysis, which aims to determine the content of various elements in metal materials. Common chemical composition analysis standards include:
- GB/T 20066: Mainly for the sampling and analysis methods of chemical composition of metal materials.
- ASTM E34: The standard provides a unified method for the chemical analysis of general metal materials.
- ISO 14284: Specifies the determination methods of elements such as carbon, sulfur, and phosphorus in metal materials.
2. Physical property test standards
Physical property tests include tests on the hardness, density, conductivity and other physical properties of metal materials. Common physical property test standards include:
- ASTM E18: Specifies the Rockwell hardness test method for metal materials.
- ISO 6507: specifies the Vickers hardness test method for metal materials.
- GB/T 230.1: specifies the Rockwell hardness test method for metal materials.
3. Mechanical properties testing standards
Mechanical properties testing involves testing various mechanical properties of metal materials, such as tension, compression, shear, torsion, bending, impact, etc. Common mechanical properties testing standards include:
- ASTM E8/E8M: specifies the tensile test method for metal materials.
- ISO 6892-1: specifies the tensile test method for metal materials.
- GB/T 228.1: specifies the tensile test method for metal materials.
4. Microstructure analysis standards
Microstructure analysis mainly focuses on the microstructure and surface morphology of metal materials, including non-metallic inclusions, low-magnification structure, grain size, fracture inspection, etc. Common microstructure analysis standards include:
- ASTM E45: specifies the evaluation method of non-metallic inclusions in metal materials.
- ISO 4968: specifies the method for determining the grain size of metal materials.
- GB/T 10561: specifies the method for evaluating non-metallic inclusions in metal materials.
5. Environmental adaptability test standards
Environmental adaptability testing includes the performance of metal materials in different environments, such as heat resistance and corrosion resistance. Common environmental adaptability test standards include:
- ASTM G15: specifies the corrosion resistance test method for metal materials.
- ISO 9227: specifies the salt spray corrosion test method for metal materials.
- GB/T 10125: specifies the salt spray corrosion test method for metal materials.
6. Nondestructive testing standards
Nondestructive testing is a non-destructive testing method that uses advanced methods such as X-ray fluorescence spectroscopy, mass spectrometry, and ion chromatography to detect internal defects in metal materials. Common nondestructive testing standards include:
- ASTM E165: specifies the penetration test method for metal materials.
- ISO 17636: specifies the magnetic particle testing method for metal materials.
- GB/T 7233: specifies the ultrasonic testing method for metal materials.
7. Specialized analysis methods
Specialized analysis methods selected according to specific needs, such as conductivity measurement, thermogravimetric analysis, etc. These methods are usually used for specific metal materials or specific application scenarios.
Summary
Metal composition analysis test standards are an important basis for ensuring the quality and performance of metal materials. By selecting the correct test methods and test standards, and strictly implementing the test steps and requirements, the accuracy and reliability of the test results can be guaranteed.
