In India, the 1600-year-old iron pillar at Mehrauli, New Delhi, is one of the world’s foremost metallurgical curiosities. Since then, steel has been used in different parts of the world for various purposes. However, there was no control on the quality of steel till the end of the 18th century when in 1885 British Steel manufacturers formed an association and laid down limits of sulphur and phosphorus in steel. It was unknowingly the first step towards control of fatigue resistance in structural steel.
