This easy drawability of UHMW-PE crystals is rather unique and unprecedented. Figure 6: The stress–strain curves of the crystals formed from heterogeneous and homogeneous melts.

Copper and phosphorus bearing high strength cold rolled steel sheets with superior drawability have been developed. The copper and phosphorus contents of these steels are 0.6% and 0.08% respectively.
