GH3625 is a high-performance nickel-based alloy sheet known for its exceptional resistance to corrosion, oxidation, and high-temperature deformation. As a trusted Chinese equivalent to Inconel 625, GH3625 complies with ASTM B444/B704 standards and is widely used in critical applications across marine, aerospace, and chemical processing industries. This alloy offers a balanced combination of strength, weldability, and resistance to aggressive environments, making it ideal for demanding industrial conditions.
Our GH3625 seamless alloy sheets are manufactured with advanced hot-rolling and precision annealing processes to ensure tight dimensional tolerances, structural integrity, and excellent surface quality. Every batch is thoroughly tested for chemical composition, mechanical performance, and microstructure, with third-party certifications available upon request.
Corrosion Resistance: Superior performance in seawater, acidic, and oxidizing environments.
High-Temperature Strength: Stable mechanical properties up to 980°C.
Weldability: Compatible with all standard welding techniques (TIG, MIG, etc.).
Customization Support: OEM dimensions, finishes, and marking services available.
Global Supply Capability: Export-ready packaging and fast international logistics.

We offer comprehensive OEM and custom processing capabilities to support diverse industrial needs:
Precision shearing, waterjet, and laser cutting
Logo stamping, barcoding, and material traceability labels
Export-grade packaging with fumigation-free wooden cases
Third-party inspections by SGS, BV, or customer-appointed agents
GH3625 is a nickel-chromium-molybdenum alloy that matches Inconel 625 in both composition and performance. It is developed as a cost-effective Chinese alternative while retaining high corrosion resistance and temperature strength.
Yes. Our products comply with ASTM B444/B704 standards and include material test certificates. Third-party inspections (SGS, TUV, BV) are also supported based on customer needs.
MOQ depends on the product form and thickness. For most standard sheet sizes, the MOQ is 50–100 kg. Samples can be provided for evaluation.
Yes, we ship worldwide. We work with reliable forwarders and can offer sea freight, air freight, and express courier options with tracking.
Standard sizes may be shipped within 7 days. Custom orders or bulk quantities typically require 10–20 working days depending on processing complexity and availability.
