2014 03 19 nbsp 0183 32 Hot Rolled Steel vs Cold Rolled Steel The first thing to remember is that the terms Hot Rolled and Cold Rolled do not refer to any grades or strengths but merely the process used to create the bar product at the mill Hot Rolled Steel is softer and more pliable than Cold Rolled Steel Hot Rolled Steel has a light grey rough finish and rounded edges
2018 09 07 nbsp 0183 32 Hot rolled steel involves rolling steel at high temperatures while cold rolled steel refers to processes done at or near room temperature Certain types of steel will work better with certain applications so understanding the differences between the hot rolling and cold rolling processes can help save time and money eliminating unnecessary processing steps and
As the metal is shaped at lower temperatures cold rolled steel offers an increased hardness of up to 20 as well as improved yield and tensile strength Furthermore parts made of cold rolled steel have a very smooth surface free of any rust and scale Hot amp cold rolling process and aluminum bronze
Hot rolling is the preferred technology for the mass production of long steel products par excellence as it is typically more economical than cold rolled steel Furthermore it allows the processed material to be formed and shaped with ease Another major benefit is that hot rolled steel is practically free from internal stresses as the steel is cooled down gradually Yet
