If the area of steel is greater than 4% than the bonding between concrete and steel can nog occur because it requires large dia bars that has less surface area and hence weaken the structure.

Minimum :It is. 85/yeild strength (%) of gross sectional area/
Maximum :6% and can be reduced to 4% under special consideration.

4 percent is too much.
According to IS 1978 AROUND 0.0162BD,

According to BS.8110, the maximum area of tension reinforcement of beams should not be more than %4. Because if more than that is used, it prevents the required compaction.

Ast/bd = 0.85/Fy ---------> for minimum reinforcement of beam.

According to ACI the minimum reinforcement should 18% for 60 grade steel and 0.2 for 40 grade steel.
