ASTM A420 WPL3 Low Temperature Alloy Steel Long Radius Elbow
Product Overview

ASTM A420 WPL3 Long Radius Elbow is a low-temperature alloy steel butt weld fitting designed for pressure piping systems where impact toughness at low temperatures is required. Manufactured in accordance with ASTM A420/A420M and dimensional requirements of ASME B16.9, the WPL3 elbow is available in long radius configurations and commonly supplied in 45° and 90° angles.

Key Characteristics
  • During welding, repeated heating precipitates carbides, reducing corrosion resistance and mechanical properties
  • Post-welding provides good hardness but susceptibility to cracking; requires preheating above 300°C and slow cooling at 700°C
  • Prevents eye corrosion with welding current approximately 20% lower than carbon steel electrodes
  • Designed for low-temperature service where impact toughness is critical
  • Long radius configuration follows ASME B16.9 dimensional requirements
  • Standardized dimensions for integration with compatible piping components
  • Material traceability with certificates and inspection documentation available
Production Process
  1. Stamping process offers high production efficiency and easy automation
  2. Material-saving and energy-efficient processing with minimal waste
  3. Capable of producing parts with wide dimensional ranges and complex shapes
  4. Cold deformation hardening enhances strength and stiffness
