Galvanic Compatibility of Metals – Anodic Index

Galvanic  Designs sometimes cause dissimilar metals to be in contact within an assembly.  Increased variance of the two metals’ anodic index cause accelerated corrosion of the more anodic metal.  The variance in anodic index can be controlled somewhat through coatings (paint, epoxy, powder coat, etc) and plating (zinc, chrome, etc). The table below provides a … Continue reading Galvanic Compatibility of Metals – Anodic Index

AISI / SAE STEEL NUMBERING SYSTEM

The first two numbers indicate the alloy according the the chart below. The last two numbers indicate the amount of carbon in the alloy, where the digits “10”, for example, represent 0.10% carbon. Example AISI/SAE 1020 the first two digits indicate this is plain carbon steel. the last two digits indicates that the steel contains … Continue reading AISI / SAE STEEL NUMBERING SYSTEM
