The aluminized 1.6582/4340 steel bar is a low-alloy, high-strength material with chromium, nickel, and molybdenum additions for superior toughness and fatigue resistance. Supplied by Dongguan Songshun Mould Steel Co., Ltd. in China, it features a vacuum-deposited aluminized coating that significantly improves corrosion resistance in harsh environments. The bars are available in diameters from 20 mm to 800 mm and lengths up to 9,000 mm, making them adaptable to heavy-duty machining and fabrication requirements.
This grade corresponds to AISI 4340, a widely recognized alloy steel used in aerospace, automotive, and oil and gas sectors for components like gears, shafts, and connecting rods. The aluminized surface not only resists oxidation at elevated temperatures but also maintains dimensional stability under cyclic loading. Standard mill certifications accompany each shipment, ensuring traceability and compliance with international metallurgical standards.
Primary buyers include manufacturers of aerospace components, automotive drivetrains, and heavy machinery parts where high tensile strength and impact resistance are critical. The material is typically sourced in bulk with custom cutting options available. Buyers should confirm surface finish requirements and heat treatment specifications, as these directly affect mechanical properties in end-use applications.

Before ordering aluminized 1.6582/4340 steel bars from Dongguan Songshun Mould Steel Co., Ltd., verify the exact alloy grade and heat treatment state, as these determine mechanical properties. Request mill certifications to confirm composition and tensile strength, and check whether the aluminized coating meets your corrosion resistance requirements. For critical applications, ask for third-party inspection reports or additional testing, such as ultrasonic examination for internal defects.
Logistics terms should be clarified upfront, including Incoterms (e.g., FOB Ningbo or CIF destination port) and packaging standards. Bars are typically bundled with steel straps and protected with waterproof paper or plastic wraps. Confirm lead times, as custom diameters or lengths may require additional processing. Payment terms often include T/T or L/C, but these should be negotiated based on order volume and supplier policies.
Quality checks should begin with visual inspection for surface defects or coating inconsistencies in the aluminized layer. Dimensional verification using calipers or micrometers ensures bars meet specified tolerances. For high-stress applications, conduct hardness testing (Brinell or Rockwell) and tensile tests on sample pieces. Document all findings and retain copies of certifications for traceability, especially for aerospace or automotive components.
