Key Selection Considerations for Equivalent Materials

 

When selecting an ASTM A516 GR 70 equivalent material, engineers must evaluate multiple factors beyond simple grade equivalence. The following considerations are critical for safe and code-compliant design.

 

Operating Temperature Environment

ASTM A516 GR 70's greatest strength is its low-temperature toughness certification to -46°C. European equivalents (P355GH) and Japanese equivalents (SPV355) generally lack this low-temperature certification. For projects involving:

  • LNG storage tanks and cryogenic service (below -20°C): Specify ASTM A516 GR 70 or arrange additional impact testing on equivalents
  • High-temperature boiler service (above 400°C): P355GH may be preferred over A516 GR 70
  • Moderate-temperature pressure vessels (0°C to 400°C): All equivalents are generally acceptable with proper engineering review

 

Code Compliance Requirements

Different jurisdictions require compliance with specific codes:

  • ASME BPVC Section II: ASTM A516 GR 70 or ASME SA516 GR 70 required
  • PED (European Pressure Equipment Directive): EN 10028-2 P355GH preferred
  • Chinese GB Code: GB 713 Q345R required for local certification
  • JIS/KHK (Japanese Code): JIS G3115 SPV355 specified

 

Welding and Fabrication Considerations

All equivalent materials offer good weldability using conventional welding methods. However, Q345R requires more careful preheating (60–150°C) and post-weld heat treatment for thick plates to prevent cold cracks and eliminate welding stress. ASTM A516 GR 70 is known for superior weldability and lower carbon equivalent values, reducing preheat requirements.
