High-strength corrosion-resistant composite chequered iron and manufacturing method therefor

A high-strength corrosion-resistant cladding chequered steel comprising a substrate and at least one chequered cladding layer cladded onto the substrate by rolling, wherein the at least one chequered cladding layer comprises a surface pattern applied thereto by a patterned roller, and the substrate comprises the following chemical elements in mass percentage:

• C:
• 0.01% to 0.20%, Si:
• 0.10% to 0.5%, Mn:
• 0.5% to 2.0%, Al:
• 0.02% to 0.04%, Ti:
• 0.005% to 0.018%, Nb:
• 0.005% to 0.020%, 0<B<0.0003%, N<0.006%, and the balance being iron and other inevitable impurities;
• wherein the substrate further comprises at least one of Ni, Cr and Mo in mass percentage:
• Ni<0.20%, Cr<0.20%, and Mo<0.10%;
• and
• wherein the thickness of the at least one chequered cladding layer is in a range of 10% to 40% of the thickness of the high-strength corrosion-resistant cladding chequered steel.
