‘SUPERSTEEL’
Researchers at the University
of Hong Kong and Lawrence
Berkeley National Labs
(LBNL) believe they have
managed to produce a type of
steel that has high-level performance
in all three key properties that need
to be balanced in steel – strength,
toughness and ductility.
This ‘Super Steel’ has a yield strength
resistance against deformation of
around 2 GigaPascals, a fracture
toughness of 102 MPa-m½, and a
uniform elongation of 1%.
Scientists are saying that they
believe this means that it’s stronger
and tougher than the Grade 300
maraging steel used in aerospace
engineering (at 20% the price tag of
manufacturing).
