As far as I know, there is no max armor or reduction. How much your armor reduces incoming physical damage, is calucalted by dividing your total armor with your total armor + 100.

Let's say you have an armor value of 157. You would then calculate 157/157+100 = 157/257 = 0.6108 = 61.08% reduced physical damage. This does not include possible enemy armor reduction or penetration, of course.
