| Steel Grade | Applications |
|---|---|
| MR (Medium Residual) | MR steel contains low levels of residual elements, making it widely suitable for general container applications.(Common container material) |
| L (Low Metalloid Steel) | L steel features very low levels of residual elements such as Cu, Ni, Cr, and Mo, making it ideal for food containers that require high corrosion resistance. (Material for containers used with highly corrosive foods) |
| D (Drawing) | D steel is aluminum-killed and is used in containers that undergo deep drawing processes or are prone to stretcher strain (Luder's Lines). (Material for process-intensive containers) |
The hardness of cold-rolled steel sheets, processed through a single pass, is indicated by the Rockwell T hardness (HR30Tm) value.
