Galvanic/Dissimilar Metal Corrosion (Version 2 - May 2009)

Contact between dissimilar metals occurs frequently but is often not a problem. The aluminum head on a cast iron block, the solder on a copper pipe, galvanising on a steel purling are common examples. The Galvanic/Dissimilar Metal Corrosion Technical FAQ provides some answers to the problem and steps on how to avoid it.

Magnetic Effects of Stainless Steel

The magnetic properties of materials are affected by their composition, metallic structure, processing methods and physical condition. Ferromagnetic materials are strongly attracted to a permanent magnet and may also be magnetised to act as a permanent magnet.

Testing for Grade Confirmation

Raw material price fluctuations and increasing demand for stainless steels have driven demand for lower cost alloys as alternatives to the traditional “300” series steels. This has been met through a range of existing and new, innovative steels with different properties, performance and availability. But as with the traditional stainless steels you can't tell what they are by looking at them. This article describes a range of test methods available for grade confirmation.

Galling and its Control

Austenitic stainless steels are widely used for corrosion resistant bolting. One of the major problems in use is that disassembly is difficult because nuts and bolts seize. This phenomenon is known as galling and it is most prevalent with intermittently operated, slowly sliding surfaces.
