Key Specifications / Features

A351 CF3 is a lower carbon variant of Grade A351 CF8 – the steel can be welded without the resulting issue of carbon precipitation (precipitation of chromium carbide as heat is applied during the welding process which depletes the chromium element of the steel thus reducing its anti-corrosive/oxidation effectiveness). It’s corrosive and strength properties are similar to A351 CF8.
