Data bends parsteel

Parsteel is a metal alloy with a tensile strength of forty kilobars (roughly 10x as strong as regular steel).

A length of parsteel was bent by the android Lieutenant Commander Data in 2365, as a demonstration of his megastrength, during a formal hearing to determine his sentience. (TNG: "The Measure Of A Man")

In the script, this metal was referred to as "plasteel."
