Since the start of the Year of the Horse, Changbao Special Materials Division has driven progress through practical action, making phased achievement in high-end product R&D, product performance validation, and international market certification. These accomplishments lay a solid foundation for accelerating the company’s transformation and upgrading towards premiumization and internationalization.

In the R&D for ultra-supercritical thermal power unit boiler tubes, Changbao Special Materials Division has deepened "Industry-Academia-Research" collaboration, forming a joint technology task force with leading upstream and downstream enterprises. Changbao high-end boiler heat-resistant materials exhibit a stress rupture strength at 650°C for 100,000 hours that exceeds the requirements of standards, reaching an industry-leading level of technical maturity and reliability. Furthermore, high-end stainless steel sample tubes have also made phased achievement in high-temperature persistent stress tests conducted by key client companies.

Meanwhile, Changbao Special Materials Division has systematically advanced a diversified portfolio of special materials projects to build a comprehensive high-end product matrix. In high-end corrosion-resistant alloys, projects for corrosion-resistant alloys for the petroleum and petrochemical sectors and nickel-based alloy OCTG have been progressing as planned, with some products already in small-batch supply. The company is also actively participating in drafting several national standards. Regarding advanced material positioning, R&D on heat-resistant steels and nickel-iron-based superalloys for 630-700°C high-efficiency ultra-supercritical units have also been proceeding steadily, now entering the sample tube manufacturing and performance evaluation stage. In terms of technological breakthroughs, the project of optimizing electrolytic polishing techniques has completed initial trials, enhancing the surface quality of tubes used in semiconductors and solidifying the technological base for expanding into high-end materials markets.

In international certification, Changbao Special Materials Division has systematically pursued multiple prestigious accreditations, including ASME/PED, DNV for duplex stainless steel, ASME BPE and 3-A for clean tubes, and JIS. It has conducted special equipment type tests and API certification for corrosion-resistant alloys, and has completed numerous product certifications in collaboration with leading companies and research institutions. Notably, substantial progress has been made in the DNV certification for duplex stainless steel, establishing the credential foundation for the company to enter high-end markets such as marine engineering.

As a benchmark project for the company’s high-end transformation, Changbao Special Materials Division will continue focusing on high-end, segmented, and branded positioning, accelerating product performance validation and the pace of domestic and international certification. Driven by technological innovation and market breakthroughs, Changbao Special Materials Division aims to expedite the development and promotion of high-end products and market access, contributing to the upgrade of China’s high-end equipment manufacturing industry.
