SAIL TMT HCR Fe 550D combines the 550 MPa grade with the corrosion-resistance properties of the HCR range. It is intended for RCC construction exposed to coastal, marine, industrial corrosion or underground environments. For Cu-Cr grade HCR TMT the total Cu+Cr is 0.75 % minimum.

Key features

• Has all qualities of SAIL TMT EQR
• High corrosion resistance properties

Applications

• RCC construction exposed to coastal, marine, industrial corrosion or underground environments
