Which code specifies rolling margin of reinforcement steel?
Is 1786-1985
Is hot-rolled steel magnetic?
Yes, hot-rolled steel is magnetic. A few types of steel have limited magnetic properties, but hot rolling is a process by which steel is prepared in a shape for marketing. The hot rolling does not affect the ability of the steel to be attracted to a magnet.
What is JIS SUS304?
Japanese standard for stainless steel grade 304.
What is meant by CS STD Wt?

What is csa w59 in welding?
Canadian Standard Association, Standard W59, covers welding requirements for carbon and low-alloy welded steel construction
Rolling margin of steel rod which is used for construction?
Rolling Margin is the deviation of actual unit weight to that of Standard unit weight as per IS Standards. Rolling Margin is calculated as : Sectional weight = Weight of Steel Bars dia wise / length of the bars. As per IS Standards unit weight of the Bars is calculated as dia x dia / 162 Rolling Margin is deviation of actual sectional weight to that of IS Standard unit weight. Standard Rolling Margin for different dia reinforcement bars used for construction purposes: 8mm to 10mm +- 7% 12mm to 16mm +- 5% 20mm & Above +- 3%

What is rolling margin for reinforced steel and how it is calculated?
Rolling margin is percentage of diviation in Sectional weight of Reinforcement steel allowable as per IS codes.Reinforcement steel is extruded from a mould which is made for a particular size e.g 8mm Dia.When the mould is brand new,the sectional weight of 8mm steel extruded through mould would exact as per IS standard of lower than that.i.e. 0.395Kg per Metre or lessor.Mould gets little bigger after certain period of time or after certain quantity of production is taken from a particular mould.Now same 8mm dia bars extruded from the same mould will have more weight per Metre say 0.400Kg per Metre insted of 0.395 as per IS. That is more mass per Metre/Length is required for same length.This diviation in weight is defined in IS codes for different dia which is as under :- 8mm to 10mm +_ 7% 12mm to 16mm+- 5%. 20mm and above+ -3%. Rolling Margin is calculated as under :- Total Weight of Bars (Dia wise ) / Total Running Metre of Bars = Actual Sectional Weight of bars. Compare sectional weight with Standard IS Weight. Weight as per IS Standard.= Dia X Dia / 162. ----
What are Changes takes place in grains of steel during rolling and annealing?
Prior to the rolling of steel, the grains of the steel are oriented in long strands of caribides in the billet form. When this billet goes through the rolling process, these strands are compressed and broken up into shorter bands. This rolling process densifies the steel and thereby work hardens the steel. These work hardened grains become too hard for any further rolling to take place and they must be annealed. The annealing process entails heating the bar or billet to about 1600 degrees F and holding for a long period of time. Through annealing, the steel grains are softened so that additional rolling can be performed. For additional information on the rolling and annealing of steel, terminology or the properties of steel, see the related link.
