Ask Deep Processing Services

Gnee stainless steel can provide testing and the following third-party inspection services. These third-party testing services provide independent and objective verification of stainless steel’s compliance with relevant standards and regulations.

Mechanical Property Testing: Used to determine whether the strength, toughness, ductility and other mechanical properties of stainless steel meet the specified requirements.
Chemical Composition Analysis: Quantitative determination of elements on stainless steel samples through spectral analysis, atomic absorption spectroscopy, inductive coupling and other technologies.
Corrosion Performance Test: Common corrosion performance test methods include salt spray corrosion test, acid-base corrosion test and electrochemical corrosion test.
Tensile Strength Test: Through the tensile test, the parameters such as yield strength, tensile strength and breaking strength of stainless steel during the tensile process are measured.
Non-Destructive Testing: Non-destructive testing is used to evaluate hidden defects, cracks and looseness in stainless steel materials. Common methods include ultrasonic testing, magnetic particle testing, eddy current testing, and radiographic testing.
Pressure Test: By exposing stainless steel products to a specific pressure, it is tested whether there are problems such as leakage or deformation to ensure that its pressure resistance meets the requirements.
Surface Quality Test: Used to evaluate the surface flatness, smoothness and oxide layer of stainless steel products.
Welding Performance Test: Check the appearance, mechanical properties and metallographic microstructure of the weld to ensure that the quality of the stainless steel welded joint meets the requirements.
Metallographic Inspection: Through metallographic inspection, the structure, grain size, non-metallic inclusions, etc. of stainless steel are checked to evaluate its quality and performance.
