Low S&P Levels
Sulphur and phosphorus (S&P) are harmful impurities in Steel. With high levels of phosphorus steel gets very brittle and there is the risk of cracking at very low temperatures. High levels of sulphur lower the melting point of steel greatly reducing its strength under high temperature conditions. Lower levels of S&P can be achieved only through advanced steel making technology. Such low S&P levels, as specified in the 500D specifications of BIS, are almost impossible to be achieved through normal scrap and induction furnace route. Beekay has state-of-the-art infrastructure and stringent quality control procedures in place to enable it to manufacture high grade TMT bars that comply with grade specifications.
