☆☆☆☆☆A "strong" acid (or base) is one that dissociates completely in dilute aqueous solution. One which does not is a "weak" acid (or base). An acid with a pKa (or a base with a pKb) lower than about -2 is considered to be a "strong" acid.
Weak acids and bases can still be quite corrosive. HF is a "weak" acid with a pKa of around 3.2 (which corresponds to only about one molecule out of every 38 or so being dissociated), but it's pretty terrible stuff and will dissolve even glass.
