The invention belongs to the technical field of steelmaking, and particularly relates to a low-cost niobium-free S355MC hot-rolled pickled plate and a production method thereof. The low-cost niobium-free S355MC hot-rolled pickled plate comprises the following components in percentage by weight: 0.03-0.08% of C, Si which is less than or equal to 0.030%,, 0.40-0.80% of Mn, P which is less than or equal to 0.020%, S which is less than or equal to 0.010%, 0.020-0.070% of Alt, 0.035-0.055% of Ti, N which is less than or equal to 0.006%, and the balance of iron and inevitable impurities. According to the low-cost niobium-free S355MC hot-rolled pickled plate and the production method thereof disclosed by the invention, niobium and a part of manganese are replaced with titanium, so that the purpose of greatly reducing the production cost is achieved, and titanium-containing steel can effectively overcome the transverse crack defects of casting slab corners and improve the surface quality of the hot-rolled pickled plate.
