Hot-rolled steel, such as JSW Steel Hot Rolled coil IS 2062:2011 E250A steel, is produced at high temperatures, typically above 1650 degrees Celsius. Silicon is often added to steel as an alloying element to improve strength and toughness. However, low silicon content is desirable in specific applications, mainly where weldability is a concern. Low-silicon steel is often easier to weld because it produces less slag and spatter during welding.
Hot Rolled Low Silicon Steel is a specialised steel category with low silicon content. The hot-rolled steel must demonstrate excellent impact resistance to effectively absorb and dissipate kinetic energy upon impact and be used for crash barriers. This property is crucial for preventing vehicle intrusion and minimising the risk of injury to occupants.
JSW Steel Hot Rolled coil IS 2062:2011 E250A steel grade typically exhibits good ductility, allowing it to deform plastically without fracturing under stress. These coils are passed through a slitting machine. The slitting process is normally precise, and you can create strips of various widths according to your requirements.
E250A steel complies with the requirements specified in the IS 2062:2011 standard set by the Bureau of Indian Standards (BIS). Carbon (C) is present at 0.23%, manganese (Mn) at 1.5%, sulphur (S) at 0.045%, phosphorus (P) at 0.045%, and traces of other elements.
