<p>PURPOSE: A high manganese silicon-containing steel sheet having high intensity and ductility is provided to control the heat treatment and cooling speed for controlling the precipitation of carbide. CONSTITUTION: A high manganese silicon-containing steel sheet having high intensity and ductility contains 0.6-1.0wt% of carbon, 8-15wt% of manganese, less than 4.0wt% of silicon, and the balance of residual iron and inevitable impurities. The multiplication of the tensile strength and the total elongation of the steel sheet is greater than 45,000 Mega Pascal.</p> |
