Heat number. An example of a heat number on a plate. A heat number is an identification coupon number that is stamped on a material plate after it is removed from the ladle and rolled at a steel mill.

A heat number is a unique identifying code a technician stamps on a piece of metal to provide information about its origins. Metal plate and pipes are most likely to bear this number, and in some cases, the law requires its use on metal products. The heat number provides a method for tracing materials and is an important part of quality assurance and control. People can usually find it near the edge or end of a finished metal piece, and other information may be on the stamp as well. There are three segments in a heat number. The first digit indicates which furnace a technician used to prepare a batch of molten metal. The next digits indicate the year of the casting, and the last two or three digits describe the number of the casting.
