HOT ROLLED STEEL

Hot rolled (HR) steel is a type of steel that is produced through a process of heating the steel above its recrystallisation temperature and then rolling it into the desired shape. The high temperature of the process makes the HR steel more malleable and easier to shape. This process also results in a rough surface texture on the steel.

Hot Rolled, Pickled and Oiled (HRPO): The HRPO sheets and coils are produced through a similar hot rolling process to a hot rolled sheet, but they undergo an additional pickling and oiling step. During the pickling process, the steel is passed through an acid bath to remove the black layer of iron oxides which forms during the hot rolling process, and to protect the surface from any moisture. The steel is then coated with oil to prevent rusting. This process improves the surface finish of the steel, making it more suitable for painting or other surface treatments.

Categorisation based on different IS standards:

IS 2062:2011 and IS 3502:2009

According to the Bureau of Indian Standards (BIS), sub-qualities A and BR stand for:

A: Impact test not required; semi-killed/killed
BR: Impact test optional; if required at room temperature; semi-killed/killed

Semi-killed steel is a metal alloy compound of iron and carbon partially deoxidised with minimal gas release during solidification. Killed steel is treated with a powerful deoxidising agent to prevent carbon-oxygen reaction during solidification.

The IS 2062 is a standard laid out by BIS, and 2011 signifies the year this standard was last revised. The IS 2062:2011 standard is for hot rolled medium and high tensile structural steel. E350 is the grade, with E standing for Engineering steel. The chequered plates of IS 3502:2009 conform to the requirements of IS 2062.

IS 1079:2017

The IS 1079:2017 standard has hot rolled carbon steel sheets, and strips. These steel products are supplied within semi-killed or killed conditions.

Hot Rolled Steel Applications

Automotive and Manufacturing Industry:

JSW Steel Hot Rolled Sheets IS 2062:2011 E250A: These sheets are commonly used in the automotive and manufacturing industries due to their versatility and strength.
