We are seeking the assistance of a metallurgist or other professional to analyze samples taken from a cache of WTC steel wreckage.

I am updating this entry since accessing the steel cache on June 2, 2011 and obtaining 16 samples and 50 additional photos.

The samples include rust, SFRM fireproofing, steel shards, concrete, slag, dust and maybe some paint.

Some of the items have SAVE NIST or ASTANEH painted on them. Check out the weird evaporation of the top flange and discoloration on the web.

One of the pieces may be a match for a WTC7 girder seen in this 1985 construction photo. Compare the piece that the samples were taken from.
