"In hot water it springs back with forces of 55 TONS a square inch"... Hmmm. Is this possible?

  To express that quantity in more familiar units, That's 758 MPa From Wikipedia article on Nickel-Titanium: "A great deal of pressure can be produced by preventing the reversion of deformed martensite to austenite—from 35,000 psi (240 MPa) to, in many cases, more than 100,000 psi (690 MPa). One of the reasons that nitinol works so hard to return to its original shape is that it is not just an ordinary metal alloy, but what is known as an intermetallic compound." So yeah, there or thereabouts. https://en.m.wikipedia.org/wiki/Nickel_titanium#Mechanism https://en.m.wikipedia.org/wiki/Nickel_titanium#Mechanism

    Perhaps there is a niche application for it in the field of gas compression.

  Consider that water itself can exert similarly tremendous pressures with phase changes.
