Q1: Maximum permissible sulphur content in steel is __________ percent.

ANS:A - 0.015

The maximum permissible sulfur content in steel is typically around 0.055 percent. Excessive sulfur content in steel can lead to a variety of issues including reduced ductility, increased brittleness, and poor weldability. Therefore, to ensure the quality and performance of steel, specifications often limit the sulfur content to levels typically around 0.055 percent or lower.
