Description
It is generally accepted that H.R Rolled Steel which is more then 4mm thick is called as H.R Plates. Plates are normally available in different grades as per the end use like for general fabrication Mild steel is used, Where their is more of wear and tear their Carbon/ Alloy Steel is used as per the requirements. When there is flow of water or chemicals in the use then Stainless Steel is used.
There are different grades of plates available as per their Chemical and Mechanical properties and their use,
Some are like the Following:- GRADES;- IS1079grade, IS2062 Grade A/B/C, SAILMA250/300/350 HI GRADES, C-45, C-55, EN SERIES LIKE EN8/9/19/24 ETC, Boiler Qualities, Stainless Steel 200,300 and 400 Series and any special quality as per Customer requirements.
