ISO 17781 Duplex Stainless Steel Certification Testing
The ISO 17781 standard is a key specification for duplex stainless steel, used in various industries such as petrochemicals, marine engineering, and aerospace. This certification testing ensures that materials meet the stringent requirements of this standard, which guarantees high resistance to chloride stress corrosion cracking (SCC) and good mechanical properties.
Our laboratory uses advanced analytical techniques including optical emission spectroscopy (OES), scanning electron microscopy (SEM), and energy-dispersive X-ray spectroscopy (EDX). These methods provide precise chemical composition analysis essential for meeting ISO 17781's stringent requirements. We also employ mechanical testing such as tensile, impact, and hardness tests to evaluate the mechanical properties of materials.
The process begins with specimen preparation where we ensure that samples are representative of the material being tested. Specimens undergo chemical analysis to confirm compliance with ISO 17781's chemical composition requirements. Next comes mechanical testing which includes tensile strength measurements, impact toughness assessments, and hardness determinations. These tests help us determine whether the material possesses the necessary properties demanded by the standard.
Following these initial checks, we conduct more detailed analyses using advanced analytical techniques like SEM/EDX to examine grain structure and phase distribution. This information is crucial for identifying any potential issues related to composition or microstructure that could affect performance under specific operating conditions.
In addition to laboratory tests, our facility also offers field testing services where samples are taken directly from production environments or end-use applications. This approach ensures that the materials behave consistently across all stages of their lifecycle—from manufacturing through operation and maintenance phases.
Our team of experienced metallurgists and materials scientists interprets results based on international standards including ISO 17781, ASTM A240, EN 10306-5:2019, and others relevant to duplex stainless steels. They provide detailed reports outlining compliance findings along with recommendations for further action if necessary.
By adhering strictly to these standards during our certification testing process, we ensure that manufacturers can confidently meet customer expectations while complying with regulatory requirements worldwide.
