Core Product Advantages
High Strength and Wear Resistance
Made from high-quality carbon steel (20#, 45#), alloy steel (40Cr, 42CrMo), and stainless steel, with tensile strength reaching 500-1200MPa. Surface hardening treatment (such as quenching and nitriding) results in hardness of HRC50-60, significantly improving wear and fatigue resistance.
Diverse Selection
Covers a full range of seamless pipes, welded pipes, and shaped pipes (square pipes, rectangular pipes, hexagonal pipes), supporting diameters from Φ8mm to Φ500mm and custom non-standard wall thicknesses to adapt to complex structural designs.
Flexible Surface Treatment
Offers phosphating, galvanizing, sandblasting, and spraying processes to enhance corrosion resistance, aesthetics, or coefficient of friction, adapting to different working conditions.
Application Areas
Automotive Manufacturing: Drive shafts, chassis brackets, suspension system components.
Engineering Machinery: Excavator boom pipes, crane support pipes, hydraulic cylinder barrels.
Agricultural Machinery: Harvester cutter bars, tractor drive shafts, irrigation equipment supports.
Automation Equipment: Industrial robot arm pipes, conveyor line guides, precision mold frames.
Hydraulic Systems: High-pressure oil pipes, pneumatic actuator bodies, valve connectors.
Technology and Quality Assurance
Strict Processes: Utilizes multiple cold working and annealing processes to eliminate internal stress and ensure stable mechanical properties; welded pipes undergo 100% online eddy current testing, and seamless pipes undergo ultrasonic testing to eliminate defects.
Standard Certifications: Complies with international standards such as GB/T 8162, ASTM A519, and DIN 2391, providing material reports and mechanical property test data (such as tensile, impact, and hardness tests).
Rapid Response: Leveraging intelligent production lines and modular inventory management, supporting small batch customization and urgent orders, reducing delivery time by 25%.
