wwwwww..ssppeecciiaallmmeettaallss..ccoomm INCONEL® alloy 625LCF® (UNS N06626) is a fatigue-resistant bellows-quality version of INCONEL alloy 625. The chemical composition and microstructure of alloy 625LCF are closely controlled. Alloy 625LCF is specially melted and processed to provide exceptional resistance to thermal and mechanical fatigue. Alloy 625LCF offers the same reliable corrosion resistance for which alloy 625 is well known throughout the marine, aerospace, processing, and automotive industries. Alloy 625LCF products offer a high level of performance for critical applications that require maximum resistance to corrosion along with optimum mechanical properties. Potential applications are aircraft ducting, containment and exhaust components, automotive flexible exhaust couplings, bellows for marine service, and chemical and petrochemical expansion joints. ® SAE specification AMS 5879 has been issued to address the superior fatigue strength and special properties only F available with INCONEL alloy 625LCF. Those requiring material with these properties must reference this C specification to ensure that they receive the desired product. While alloy 625LCF meets all properties specified for the conventional grade of alloy 625 (e.g., ASTM B 443 and SAE AMS 5599), conventionally produced alloy 625 L will not meet the requirements of AMS 5879. INCONEL alloy 625LCF must be specifically referenced. 5 The limiting chemical composition of INCONEL alloy 625LCF i
