At the national level, the "dual carbon" strategy and new material industry plan provide strong support: the "Carbon Peaking Action Plan by 2030" includes stainless steel pipes in the green material recommendation list. Enterprises using recycled stainless steel raw materials can enjoy a 70% VAT rebate for immediate collection and refund; the Ministry of Industry and Information Technology has established special research and development funds, giving subsidies of up to 50 million yuan for key products such as high temperature and pressure resistance and chloride ion corrosion resistance. Industry standards are continuously upgraded: the "General Specification for Seismic Resistance in Construction and Municipal Engineering" requires that coastal high salt spray areas must use corrosion-resistant stainless steel pipes of grade C5-I or above, promoting the penetration rate in municipal projects from 12% in 2020 to 28% in 2023. Local policies take precise actions: Zhejiang and Guangdong provide subsidies of 3% of the project cost for stainless steel pipes for ocean engineering; Shanghai stipulates that newly built affordable housing, hospitals and schools must use stainless steel water supply and drainage pipes from 2024, forming a national promotion synergy.

The global market presents a pattern of "Asia-Pacific dominance, emerging market rise, and European and American closure". China's output accounts for more than 55% of the global total, but it faces challenges of trade barriers: the EU's CBAM mechanism requires the disclosure of carbon footprints, and uncertified products will face carbon tariffs of 45-68 euros per ton; policies such as the US IRA and the EU CRMA raise entry barriers. In terms of response strategies, leading enterprises accelerate international certification and local layout — Jubilant Special Steel and Baosteel Special Steel obtained certifications such as NORSOK to enter major European hydrogen energy projects and Saudi NEOM projects; some enterprises build processing industrial parks in Southeast Asia to approach the demand market and avoid tariff risks. Domestic substitution has entered a deep-water stage. In addition to high-end pipes for semiconductors and aerospace, fields such as nuclear power and LNG have achieved 85% self-sufficiency rate. In the next five years, the focus will be on breaking through the "stuck neck" materials and precision processing technologies.

From 2026 to 2030, the industry will enter a competition stage centered on technical barriers, green compliance and global certification. Enterprises need to build an integrated model of "materials + services + solutions", and build moats by focusing on track segments such as nuclear power, LNG and semiconductors. Green manufacturing has become an essential capability; short-process smelting based on hydrogen, green power substitution and full-process carbon footprint management will be popularized. Enterprises with EPD certification and mutual recognition of international carbon data will obtain premium advantages. The division of labor in the industrial chain will evolve towards specialization: upstream focuses on special alloy research and development, midstream deepens precision processing, and downstream strengthens system integration. The whole-chain service capability has become the core competitiveness of enterprises, promoting the industry to transform from "scale expansion" to "in-depth value development".
