A105 carbon steel plate contains 0.25-0.35% carbon (in accordance with ASTM A105 forging standard), 0.60-1.05% manganese, and normalized to ensure yield strength ≥250MPa (measured average 285MPa), tensile strength ≥485MPa (20% higher than ordinary carbon steel). Low temperature impact toughness ≥20J at -29℃ (ASTM A370 standard), high temperature performance yield strength retention rate >92% at 204℃ (ASME B16.5 certification).
Its core value lies in: the cost per ton is only 1/6 of stainless steel, and the comprehensive manufacturing cost of high-pressure flanges is reduced by 40%; the yield rate of 50mm thick forgings reaches 98% (industry average 92%), and a single batch of 10,000 pieces saves $15,000 in materials.
We provide precision plasma cutting services (tolerance ±0.5mm, in line with EN ISO 9013 Class 1 standard) and three-dimensional leveling (flatness ≤0.3mm/m). The surface is sandblasted to Sa 2.5 (SSPC-SP10 standard) and pre-coated with peelable glue (anti-scratch validity period of 12 months). We exclusively provide forging die optimization design (material flow line qualification rate increased by 25%) and ultrasonic flaw detection prefabricated grooves (in line with ASME B16.34 valve standard).
The company adopts 40MN fast forging unit (forging ratio ≥5:1), equipped with fully automatic temperature-controlled normalizing line (grain size 7). The annual production capacity is 80,000 tons, the standing inventory is 8,000 tons (including 25/50/100mm flange special specifications), and the daily delivery volume is ≥300 tons. Each batch is tested by direct reading spectrometer (C/Mn/P/S error <0.008%) and pendulum impact tester (-29℃ Charpy V-notch report).
If the customized order is overdue, we will bear the air freight + 5% of the total order amount as compensation. We support A105 carbon steel plate sample delivery service, and support full compensation for product quality problems.
