Wire rods for ultra tensile steel cord

$15.00

The occurrence of delamination is the biggest problem for strengthening steel cord filament. Our studies reveal that delamination initiates from free ferrite and that optimization of steel grades and heat treatment for reduction of the free ferrite is useful in preventing delamination. An application of new steel grades and the above concepts achieve a tensile strength of more than 4,000 MPa.
