Inconel Alloy 625 Plate for Marine Equipment in South Korea

Shangyou supported a marine-equipment requirement for Nickel Alloy 625 plate. The buyer’s priorities included authentic UNS N06625 identification, the correct ASTM product-form standard, a defined condition, controlled cutting and documentary traceability because Alloy 625 commands a substantially different cost and performance level from stainless steel.

The plate was intended for a marine component where chloride corrosion, strength and fabrication reliability mattered. Key risks included ordering the wrong B443 grade/condition, excessive heat input during cutting, incomplete traceability and assuming Alloy 625 is immune to every marine corrosion mechanism.

• Confirmed ASTM B443, UNS N06625 and the required Grade 1 or Grade 2 condition.
• Reviewed dimensions, flatness, surface and cutting method.
• Maintained piece-to-certificate traceability after cutting.
• Coordinated PMI and any agreed mechanical or corrosion testing.
• Used separated, moisture-resistant packing to prevent damage and contamination.
  

  

  

Insert verified fit-up, weld procedure acceptance, inspection release and arrival condition.

Alloy 625 performs well in many chloride and marine environments, but galvanic coupling, crevice geometry, temperature and specific media still require design review. For precipitation-hardened high-strength requirements, compare Alloy 718; for certain reducing chemical environments, compare C-276.
