What does “critical humidity” mean?

In general, when relative humidity increases in proportion with corrosion. When Humidity increases, so does corrosion. BUT, the rate of this corrosion will increase rapidly when the humidity exceeds a certain threshold. This threshold refers to as critical humidity, which is basically more than 60 ~ 60%. However, this critical humidity varies with different metal materials.
