The tensile deformation and fracture characteristics of two ship plate steels and one low-alloy steel were determined from 25C (77F) to -196C (-321F). Both smooth and notched specimens were used and the true stress-natural strain data conform to the relation -- in the strain interva1 0.075 < - < 0.30 The strength coefficient -- was to increase regularly with decreasing temperature@ whereas the strain hardening exponent n of the ship steels dropped to a relatively low value at low temperature.
