Actually, you'll find some difficulty when trying to cut 9% chrome steel with oxyfuel. This is because the chrome oxyde formed has a higher melting point than iron oxyde. Remember that oxyfuel cutting is based on the formation of iron oxyde, that has a lower melting point than iron. So, the oxyde melts down, and you see it as big red drops falling from the metal, while iron remains solid.
Now, as 3.2 says, you can still cut it with oxyfuel, provided you take the necessary precautions.
