I found your site while surfing the Web on corrosion and metallurgy topics. It appeared to me that some the inspection people may be interested in corrosion since corrosion damage and associated cracking are one of the things they are often asked to find.
This message is also to provide a link to CorrosionSource, which is the largest and most active corrosion resource site on the Internet. It has over 30,000 pages of technincal content and over 90 percent is free. This site will also have increasing e-commerce capabilties throughout the year.
If you have any need for an additional opinion on corrosion or where to inspect for it, please feel free to contact me directly by email.
