<p>Provided is a steel sheet for an oil sand slurry pipe having excellent abrasion resistance, corrosion resistance, and low-temperature toughness including 0.2 wt% to 0.35 wt% of carbon (C), 0.1 wt% to 0.5 wt% of silicon (Si), 0.5 wt% to 1.8 wt% of manganese (Mn), 0.1 wt% to 0.6 wt% of nickel (Ni), 0.005 wt% to 0.05 wt% of niobium (Nb), 0.005 wt% to 0.02 wt% of titanium (Ti), 0.03 wt% or less of phosphorous (P), 0.03 wt% or less of sulfur (S), 0.05 wt% or less (excluding 0 wt%) of aluminum (Al), 0.01 wt% or less (excluding 0 wt%) of nitrogen (N), and iron (Fe) as well as other unavoidable impurities as a remainder. According to an aspect of the present invention, a component system and a microstructure of steel may be controlled to obtain a steel sheet for an oil sand slurry pipe which may be produced as a pipe and may also have good economic factors and production efficiency as well as excellent abrasion resistance, improved corrosion resistance, and excellent low-temperature impact toughness even in a severely abrasive environment such as that of an oil sand slurry pipe.</p> |
