I am not sure about it but recently some manufacturing companies started to emboss identification marks on steel to identify the factory unit where it is manufactured.

i had some issues with received steel, so i called a manufacturer representative, he checked that identification mark and identified its source of manufacturing.

This helps brands to identify which units works correctly and which units get issues / rejection and not qualifying minimum stated requirement as per the grade of steel.
