The Applied Technical Services Family of Companies (ATS FoC) provides comprehensive testing aligned with ISO 3651‑2, helping clients verify material performance and compliance with global quality requirements.
ISO 3651‑2 defines international standards for determining the resistance of metallic materials to intergranular corrosion. This specification ensures that stainless steels and related alloys maintain structural integrity under demanding conditions.
How Does ISO 3651-2 Support Material Reliability?
ATS delivers ISO 3651‑2 testing with precision and consistency. Our metallurgical laboratories operate under strict quality management systems, ensuring every test meets international standards. ATS and SGS employ experienced technicians and engineers, applying advanced equipment to evaluate corrosion resistance accurately. Our professional approach includes:
- ISO 17025:2017-accredited, ISO 9001:2015-registered testing laboratories
- Detailed reporting with clear data interpretation and compliance documentation
- Efficient turnaround times
- Technical consultation to help clients understand results and corrective actions
Our team’s expertise ensures that clients receive reliable, actionable insights rather than raw data alone. This helps clients by identifying any possible issues with material reliability early on.
Who Requires ISO 3651‑2 Testing
This service is essential for industries where corrosion resistance directly affects safety, durability, and regulatory compliance. Our clients include:
- Stainless steel component manufacturers operating in the automotive, aerospace, and energy sectors
- Fabricators and welders producing pressure vessels, pipelines, and structural assemblies
- Quality assurance departments verifying material certifications before production
- Engineering firms designing systems exposed to corrosive environments
By confirming that materials meet ISO 3651‑2 criteria, our clients reduce risk and maintain product reliability.
The Importance of ISO 3651‑2 Compliance
Intergranular corrosion can compromise the mechanical strength of stainless steels, leading to premature failure. Testing under ISO 3651‑2 identifies susceptibility early, preventing costly downtime and safety hazards.
Benefits of compliance include improved product longevity through corrosion resistance verification, regulatory assurance for international trade and certification requirements, improved confidence in the quality and performance of materials, and reduced liability through demonstrated adherence to ISO 3651-2.
