ASTM A36 carbon steel plate has a carbon content of ≤0.26% (in compliance with ASTM A36 standard), a manganese content of ≥0.75%, and a guaranteed yield strength of ≥250MPa (measured average value of 280MPa, exceeding the national standard Q235 of 205MPa), and a tensile strength of 400-550MPa. Impact toughness at -30℃ low temperature environment is ≥27J (GB/T 229 standard), and fire resistance performance has a strength retention rate of >65% at 600℃ (EN 1363-1 certification).
Its cost-effectiveness advantage is significant: the cost per ton is only 1/5 of that of stainless steel, and the comprehensive cost of building frames is reduced by 35%; 8mm thickness can replace ordinary 10mm plates, saving $8,200 in freight for a single project (load capacity increased by 15%).
We provide ASTM A36 carbon steel plate flame cutting services (tolerance ±0.8mm, in line with ISO 9013 Class 2 standard) and laser leveling (flatness ≤1mm/m²). The surface is shot blasted to Sa 2.5 (GB 8923 standard) and pre-coated with anti-rust oil (film thickness 8μm, storage anti-rust period extended to 6 months). We provide free CAD nesting optimization (material utilization rate increased by 18%) and weld groove prefabrication (in line with AWS D1.1 bridge welding specification).
The integrated continuous casting and rolling process (rolling speed 12m/min) is adopted, and the austenite grain size (ASTM 7-8 grade) is precisely controlled with the fully automatic controlled cooling line, achieving the industry's top precision of thickness tolerance ±0.15mm.
The annual production capacity is 500,000 tons, and 50,000 tons of inventory is always available (including 6mm/10mm/20mm hot-selling specifications in stock), supporting daily delivery of 1,200 tons of emergency orders to meet the zero-disconnection requirements of large-scale engineering projects. Each batch is tested by spectrometer composition (C/Mn/S/P error <0.01%) and universal testing machine mechanical test (with yield/tensile/elongation report).
100 tons ASTM A36 carbon steel plate order enjoys 5% discount, 500 tons order enjoys permanent key customer price (8% lower than the market average price) + free storage for 30 days. If the product has quality problems, a full refund will be given. Provide various product test reports.
