The successful completion of the Singapore project underscores our commitment to providing world-class alloy solutions. At Wuxi Xinshanhu Steel Co., Ltd., we don't just supply metal; we provide the structural foundation for global energy infrastructure.
Project Spotlight: Reliability in High-Stress Refining Environments
In the first quarter of 2026, Wuxi Xinshanhu Steel Co., Ltd. reached a significant milestone by completing the delivery of high-grade Hastelloy C-276 (UNS N10276) plates for a large-scale refinery expansion in Singapore. The project required materials capable of withstanding extreme desulfurization processes and aggressive chloride environments.
Why C-276 was the Primary Choice
Refinery operations in coastal regions like Singapore face dual challenges: internal chemical corrosion from sour crude processing and external salt-air exposure. Alloy C-276 is widely considered the most versatile corrosion-resistant alloy available, thanks to its high Tungsten (W) and Molybdenum (Mo) content.

Ensuring Success: Quality Control at Wuxi Xinshanhu
For this Singaporean partnership, Wuxi Xinshanhu Steel Co., Ltd. implemented a rigorous "Zero-Defect" protocol:
Strict Tolerance Matching: Every plate was precision-cut to the exact dimensions required for the refinery's heat exchangers and pressure vessels.
Chemical Verification: Third-party ultrasonic and chemical analysis (PMI) confirmed the critical Chromium (16%) and Molybdenum (16%) balance.
Logistics Coordination: Strategic shipping from our Wuxi facility ensured the project stayed on schedule despite the complex international supply chain requirements.
