AM/NS ROCKSTAR 400 Plates & Sheets
Rockstar is the range of high hardness, low alloyed martensitic steels. This abrasion resistant steel obtains hardness through intense water quenching and tempering process. Rockstar plates are available in three nominal hardness levels: 400, 450 and 500 BHN. Rockstar plates are optimised to provide high hardness, toughness, good formability.
We M/s New Arise Metal have wide range of ready stock in Rockstar 400, Rockstar 450 & Rockstar 500 Plates & Sheets from AM/NS India (ArcelorMittal Nippon Steel India)
For any requirment you can contact us.
