Established in 2017, PT Obsidian Stainless Steel (OSS) is an integrated stainless steel smelting project developed by XMXYG CORPORATION in Southeast Sulawesi, Indonesia, with an annual production capacity of 2.5 million tons. The project is listed among China's key Belt and Road Initiative projects and has also been designated as a National Strategic Project by the Government of Indonesia.
Leveraging XMXYG CORPORATION's strengths in supply chain management and logistics, the project serves as a catalyst for enhanced cross-border connectivity, deeper trade and investment cooperation, and the international expansion of China’s competitive industrial capabilities. The project not only helps meet the growing demand for stainless steel in the Chinese market and strengthens the global competitiveness of the stainless steel industry value chain, but also makes significant contributions to Indonesia’s industrial development, employment generation, and infrastructure improvement. Furthermore, it has played an important role in deepening economic and trade cooperation while fostering closer cultural exchanges between China and Indonesia.
OSS Industrial Plant Area
XMXYG CORPORATION has officially approved the investment in and construction of the "XMXYG Indonesia Integrated Stainless Steel Smelting Project."
The OSS project was included in China’s key project database under the Belt and Road Initiative (BRI). Riding the momentum of the Belt and Road Initiative, XMXYG CORPORATION officially embarked on its overseas development journey, carrying forward the spirit of the ancient Maritime Silk Road and opening a new chapter of international growth for Chinese state-owned enterprises in the new era.
The project’s No. 1 220kV Main Substation, as the first physical production unit to be commissioned, successfully completed its initial reverse power transmission on the first attempt. This milestone marked a critical breakthrough in the project’s development and signaled the dawn of its commercial operation.
Since entering full operation, we have continuously improved our production management system to ensure stable plant operations and steadily expand production capacity. At the same time, we have optimized our supply chain to enhance market competitiveness. Building on this foundation, we have actively implemented a localization strategy by strengthening the technical skills and management capabilities of local employees, laying a solid foundation for the company’s long-term and sustainable development.
