Astm a36 steel plate is a structural quality mild carbon steel used in general construction applications including bolted or welded construction of buildings bridges and common machine parts. 253 330 333 304 309 316 321 347 410 446 2205 2507 2101 17 4 17 5 800 tolerances listed were taken from astm a480 reference only cold rolled coil. 1 1 this specification covers the general requirements for steel sheet in coils and cut lengths. The following charts give typical astm and ansi steel sheet mechanical tolerance ranges.

The tolerances in the table and attachments reflect current manufacturing practices and commercial standards and are not representative of the manufacturer s standard gauge which has no inherent tolerances.
