Product Description

Product Description

1. Material Composition & Key Properties

• Primary Components:

  • Carbon (C): ≤0.30% (balanced for strength and weldability).

  • Manganese (Mn): 0.60-1.35% (enhances toughness and hardenability).

  • Silicon (Si): 0.10-0.50% (improves deoxidation and strength).

  • Phosphorus (P) & Sulfur (S): ≤0.05% each (controlled for ductility).

• Mechanical Properties:

  Property	Value
  Tensile Strength	≥415 MPa (60,200 psi)
  Yield Strength	≥240 MPa (34,800 psi)
  Elongation	≥25% (in 50mm gauge length)
  Hardness	≤170 HB (Brinell)

 

2. Key Features & Advantages

• High Strength-to-Weight Ratio: Ideal for structural and mechanical load-bearing applications.

• Superior Weldability: Low carbon equivalent (CE) minimizes cracking risks during welding.

• Temperature Resistance: Suitable for service temperatures up to 400°C (752°F).

• Uniform Microstructure: Seamless manufacturing ensures consistent wall thickness and reliability.

 

3. Manufacturing Process

• Hot-Rolled Seamless Production:

  • Billet heating, piercing, elongation, and sizing via rotary forging.

  • Heat treatment (normalizing or stress-relieving) to optimize mechanical properties.

• Surface Finish:

  • Black (Ungalvanized): For indoor or corrosion-protected environments.

  • Galvanized (Optional): Zinc-coated for outdoor/rust-prone applications.

• Quality Control:

  • Hydrostatic Testing: Validates leak-proof performance under pressure.

  • Ultrasonic Testing (UT): Detects internal defects in seamless pipes.

  • Chemical Analysis: Verified via spectrographic testing.

 

4. Applications

• Construction: Structural columns, trusses, and heavy machinery frames.

• Energy Sector: Steam lines, boiler tubes, and heat exchanger components.

• Oil & Gas: Transmission pipelines and refinery equipment.

• Transportation: Axle sleeves, hydraulic systems, and trailer components.

 

5. Compliance & Standards

• Primary Standards:

  • ASTM A106: Seamless carbon steel pipe for high-temperature service.

  • ASTM A53: General-purpose seamless and welded steel pipe.

• Complementary Certifications:

  • ASME SA106/SA53 (pressure system compliance).

  • ISO 3183 (petroleum and natural gas industry).

 

6. Competitive Advantages

• Dimensional Precision: Available in sizes from 1/2" to 24" OD, with wall thicknesses up to 12.7mm (0.5").

• Certifications:

  • Mill Test Certificates (MTC) with full traceability.

  • Compliance with ISO 9001 and API Q1 quality standards.

• Customization:

  • Beveled ends, threaded connections, or custom coatings (epoxy, FBE).
