ASTM A519 Seamless Mechanical Tubing

Product Specifications: ASTM A519 Seamless Mechanical Tubing

  • Material Grades:
  • Carbon Steel: 1008, 1010, 1015, 1018, 1020, 1025, 1045.
  • Alloy Steel: AISI 4130, 4140 (ideal for high-stress environments).
  • Dimensions:
  • Outer Diameter (OD): 10 mm to 324 mm.
  • Wall Thickness (WT): 1 mm to 30 mm.
  • Length: Custom lengths up to 14,000 mm.
  • Shapes: Round, square, rectangular, and custom profiles.
  • Heat Treatment: Solution annealing at 1120°C (2050°F) followed by rapid cooling (water quenching or air cooling) to enhance strength and corrosion resistance.

Manufacturing Process

  • 1. Material Selection: High-quality carbon/alloy steel billets are chosen to comply with ASTM A519 standards.
  • 2. Hot and Cold Finishing:
  • Hot Extrusion: For larger diameters, ensuring structural integrity.
  • Cold Drawing: Achieves precise dimensions and smooth surfaces for hydraulic and mechanical systems.
  • 3. Heat Treatment: Solution annealing refines the microstructure, improving toughness and resistance to stress corrosion cracking (SCC).
  • 4. Surface Protection: Oil coating applied to prevent rust during storage and transit.
Key Applications in U.S. Industries
  • Automotive (Detroit, MI): Engine components, chassis parts, and fuel injection systems.
  • Aerospace (Seattle, WA): Landing gear and structural frames requiring lightweight, high-strength AISI 4130/4140 alloy tubing.
  • Construction (New York, NY): High-rise buildings and bridges utilizing tubing for load-bearing structures.
  • Oil & Gas (Houston, TX): Drilling equipment and pipelines demanding corrosion-resistant, high-pressure tubing.
  • Heavy Machinery (Chicago, IL): Agricultural and mining equipment reliant on durable, wear-resistant tubing.
Quality Assurance & Certifications
  • Compliance: Meets ASTM A519/A519M, ASME SA519, and EN 10204/3.1B standards.
  • Testing Protocols:
  • Mechanical Tests: Tensile strength, hardness (Rockwell/Brinell), and impact resistance.
  • Non-Destructive Testing (NDT): 100% radiography (RT) and ultrasonic testing (UT) to detect internal flaws.
  • Chemical Analysis: Spectro testing ensures precise alloy composition (C, Mn, Cr, Mo).
  • Certifications: NACE MR 01075 for sour service environments.
