Grade 50W Weathering Steel Plate from Mexico
Hot-rolled Grade 50W high-strength low-alloy weathering steel plate, 18 mm thick, 1800 mm width, not further worked. Yield strength 50 ksi (345 MPa) qualifies as high-strength steel; atmospheric corrosion resistance from copper addition but remains nonalloy steel.

Import Tips
• Verify total alloy content <2% to remain nonalloy steel; weathering elements like Cu/P don't change classification
• Document hot-rolling process and absence of post-rolling treatments to prevent 7211 reclassification
