Can x-ray machine penetrate 60mm iron?

There are more types of X-ray machines, penetration also varies, respectively, 14mm steel plate, 38mm steel plate, 40mm steel plate and 43mm steel plate, of which the penetration of 40mm steel plate is the most common. X-ray machine penetration of iron is generally not more than 32mm (except for individual large-scale machine), so less than 60mm, so the current X-ray machine can not penetrate 60mm iron.
