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. Industry quality standards require materials to be tested at the manufacturer and the results of these tests be submitted through a report, also called a Mill Sheet, Mill Certificate or Mill Test Certificate (MTC).
Best Answer: The critical temperature for steel starts at 900Â°C for pure iron, then, as more carbon is added, the temperature falls to a minimum 724Â°C for eutectic steel (steel with only .83% by weight of carbon in it). As 2.1 % carbon (by mass) is approached, the critical temperature climbs back up, to 1130Â°C.
