Internal Corrosion of Aluminum Compressed Air Cylinders

Aluminum compressed air cylinder safety has been an important issue in recent years. Safety procedures regarding the use, care and maintenance of compressed air cylinders have been in placed to ensure the public safety. Many attentions have been paid especially so-called sustained-load cracking (SLC) failures. SLC is a metallurgical anomaly that occasionally develops in high-pressure cylinders made generally from aluminum alloys. 

The objective of investigation is to clarify the mechanisms of corrosion-induced pitting and cracking of the aluminum compressed air cylinder for the purpose of determining key factors.
