Ding Testing Inspection: Sodium Hydroxide Corrosion Testing, Safeguarding the Corrosion Resistance of Duplex Stainless Steel
Sodium hydroxide corrosion testing is a metallographic analysis method used to detect harmful metallurgical structures in duplex stainless steel and their impact on the material's toughness and corrosion resistance. Ding Testing Inspection offers sodium hydroxide corrosion testing specifically designed to assess the corrosion resistance and metallurgical structure stability of duplex stainless steel materials, ensuring their performance and reliability in harsh environments.
Service Introduction
The purpose of sodium hydroxide corrosion testing is to detect intermetallic phases in duplex stainless steel that significantly affect the metal's toughness and corrosion resistance. If the reduction in toughness and corrosion resistance is due to other causes, this testing method may not necessarily detect them.
Sodium hydroxide corrosion testing can be used in material acceptance but should not be the sole basis for rejection. This testing method can be used in conjunction with other evaluation tests to quickly identify samples that do not exhibit harmful metallurgical structures in other tests.
These testing methods include:
- Method A: Sodium hydroxide corrosion testing for classifying the corrosion structure of duplex stainless steel
- Method B: Charpy impact testing for classifying the structure of duplex stainless steel
- Method C: Ferric chloride corrosion testing for classifying the structure of duplex stainless steel
Industry Pain Points
The industry pain point is that duplex stainless steel may form harmful intermetallic phases under specific environments, which can significantly reduce the material's toughness and corrosion resistance, leading to decreased material performance and potential failure risks.
Service Scope
Ding Testing Inspection's service scope is extensive, covering sodium hydroxide corrosion testing, including but not limited to:
