The tank will last a few years but will turn black on the inside particularly at the acid contact surface. This material will sluff off as a very fine particulate and discolor the acid. This behavior is seen at room temperature. I believe the situation get worse faster at elevated temperature. Surface fluorination can slow the process down slightly but you are better off just changing out tanks every few years.
