What is a melt number?
The MTR document contains heat number which is also known as “melt number” and is similar to lot or batch number. When the steel plate is in its molten condition, a sample is drawn out from the batch for analysis of its chemical composition. This plate is given a particular identification number known as heat number.
What is a heat number in steel?
