Component analysis is a technology that analyzes the components of products or samples through microscopic spectra and laser femtosecond detection of molecular structures, and conducts qualitative and quantitative analysis of each component. It is mainly used to analyze unknown substances, unknown components, etc. The component analysis technology can quickly determine what the various components in the target sample are, helping you conduct qualitative and quantitative analysis of the sample, identify the material of polymer materials such as rubber, etc. Raw materials, additives, specific ingredients and content, foreign matter, etc.
Stainless steel composition analysis and testing items:
1. Elemental analysis: Detect the main and trace elements in stainless steel, such as iron (Fe), chromium (Cr), carbon (C), nickel (Ni), molybdenum (Mo), niobium (Nb), titanium (Ti) ), nitrogen (N), phosphorus (P), sulfur (S), etc. The content of these elements has a significant impact on the performance and characteristics of stainless steel.
2. Stainless steel grade identification: By detecting the content and proportion of each element in stainless steel, determine its specific grade, such as 304, 316, etc. This helps to evaluate the quality of stainless steel materials and the environment in which they are used.
3. Physical performance testing: including magnetic properties, electrical properties, thermal properties, oxidation resistance, wear resistance, salt spray, corrosion, density, thermal expansion coefficient, elastic modulus, hardness, etc.
4. Chemical performance testing: including atmospheric corrosion, intergranular corrosion, stress corrosion, pitting corrosion, corrosion fatigue, artificial atmosphere corrosion and other performance testing. These tests evaluate the corrosion resistance of stainless steel in specific environments.
5. Mechanical property testing: including tensile, bending, yield strength test, fatigue, transfer, stress, stress relaxation, impact, wear, hardness, hydraulic pressure resistance, tensile creep, flaring, flattening, compression, front cutting Strength etc. These tests evaluate the mechanical properties and load-bearing capacity of stainless steel.
6. Process performance testing: including filament stretching, fracture testing, repeated bending, two-way torsion, hydraulic testing, flaring, bending, crimping, flattening, ring expansion, ring stretching, microstructure, and metallographic structure testing wait. These tests evaluate the processing properties and manufacturing processes of stainless steel.
7. Non-destructive testing: including X-ray non-destructive testing, electromagnetic ultrasound, ultrasonic testing, eddy current testing, magnetic flux leakage testing, penetrant testing, magnetic particle testing, etc. These non-destructive testing methods can detect internal defects and damage in stainless steel without damaging the material.
Component detection function:
1. Quality control and understanding of raw material ingredients;
2. Analyze product components and restore the basic formula;
3. Prove that the product does not contain certain ingredients;
4. Find the reasons for product performance degradation;
5. Understand the ingredient content and master product performance;
6. Solve problems that arise during the production process;
7. Compare products from different periods;
8. Quickly find the causes of unknown objects and eliminate hidden dangers;
9. Improve product formula and imitate production.
