Core Application Domains for Inox

Stainless steel, with its characteristics of corrosion resistance, high strength, and ease of processing, has become a key material in overseas fields such as new energy, chemical industry, marine engineering, and construction. Combining our company’s product advantages, the following will elaborate on the practical application value and market adaptation strategies of stainless steel from four core application scenarios.

1. New Energy Field: High-end Stainless Steel Empowers Green Energy Upgrade
   The new energy industry has extremely high requirements for the corrosion resistance and precision of materials. Our 316L MOD austenitic stainless steel seamless pipes and 304 stainless steel plates are widely used in this field, covering three sub-scenarios: photovoltaic, lithium battery, and hydrogen energy.
   Photovoltaic industry: Used for the support system and fluid pipelines of photovoltaic power stations in Europe and Southeast Asia. 316L MOD pipes have high resistance to high salt fog (PREN ≥ 42) and UV aging, suitable for coastal and tropical area photovoltaic projects, such as the support connection pieces of the photovoltaic power station in the German North Sea coast and the cooling fluid pipelines of the photovoltaic energy storage station in Malaysia, ensuring the stable operation of equipment in humid and highly corrosive environments for more than 20 years.
   Lithium battery production: Suitable for the electrolyte transportation pipelines and electrode manufacturing equipment of North American, Japanese, and South Korean lithium battery factories. 316L MOD pipes adopt cold drawing and precision rolling processes, with an inner wall smoothness of Ra0.8 μm, avoiding electrolyte residue contamination, and being resistant to corrosive media such as sulfuric acid and lithium salts. They have already been applied in the Tesla Nevada Super Factory in the United States and the Samsung SDI battery workshop in South Korea, meeting the daily production demand of 100,000 batteries.
   Hydrogen energy field: Used for the inner liner and transportation pipelines of hydrogen energy infrastructure in Europe. Our customized 316L stainless steel plates (thickness 3-10mm) pass the hydrogen embrittlement test and can withstand a high pressure of 35 MPa, suitable for the hydrogen filling station in Munich, Germany and the hydrogen transportation pipeline project in Norway, helping to implement the overseas hydrogen energy industry chain.
2. Chemical Industry: Corrosion-resistant Stainless Steel Ensures Production Safety
   The chemical industry often comes into contact with strong acids, strong alkalis, and high-temperature media. Our 316L stainless steel seamless pipes and 2205 duplex stainless steel pipe fittings are preferred materials for overseas chemical enterprises, mainly used in:
   Basic chemicals: Large petrochemical plants in the Middle East and India’s crude oil refining pipelines and reaction vessel accessories. 2205 duplex stainless steel pipe fittings have a tensile strength of 620 MPa and are resistant to chloride ion corrosion (able to withstand 20% concentration hydrochloric acid), suitable for the crude oil desulfurization device in the Jubaely Petrochemical City in Saudi Arabia and the ammonia pipeline in the fertilizer factory in Gujarat, India, solving the problem of traditional carbon steel corrosion and leakage, extending the equipment maintenance cycle from 6 months to 3 years.
   Fine chemicals: Solvent transportation and purification equipment for European and North American pharmaceutical chemical enterprises. 316L stainless steel pipes have smooth inner walls without burrs and are resistant to organic solvents (such as ethanol and acetone), meeting FDA food-grade certification, applied in the drug synthesis workshop of Bayer Pharmaceuticals in Germany and the solvent recovery system of DuPont Fine Chemicals in the United States, ensuring product purity and production safety.
3. Marine Engineering: Weather-resistant Stainless Steel for Harsh Marine Environments
   Global marine engineering (such as offshore platforms, shipbuilding, and cross-sea bridges) has strict requirements for materials’ resistance to seawater corrosion and wind and wave impact. Our 317L stainless steel profiles and 904L super stainless steel plates can be adapted to different sea areas:
   Offshore oil and gas platforms: Used for platform components and oil transportation pipelines in deep-sea oil fields in Brazil and Norwegian North Sea. 904L super stainless steel contains high nickel (23%-28%) and high molybdenum (4.0%-5.0%), and can withstand deep-sea low temperatures (-20℃) and seawater corrosion. It has been applied in Brazil National Oil Company’s FPSO (floating production, storage and offloading unit) and the railing system of Norway’s Equinor’s offshore platforms, with a service life of over 40 years.

Shipbuilding: Suitable for the ship ballast water system and engine room pipelines of Korean and Japanese shipyards. 317L stainless steel pipe materials are resistant to seawater erosion and form a stable oxide film after passivation treatment, which is applied in LNG transport ships of Hyundai Heavy Industries in South Korea and container ships of Mitsubishi Heavy Industries in Japan, reducing the corrosion failure rate of seawater pipelines on ships.

Four. Construction and Decoration Field: Stainless steel enhances the quality and durability of spaces​
Overseas high-end buildings and public facilities have significant demands for the aesthetic and durability of materials. Our 304 stainless steel decorative pipes and colored stainless steel plates are widely used in:
High-end commercial buildings: Shopping centers and hotel facades and interiors in Europe and the Middle East. 304 decorative pipes (diameter 10-100mm) can be processed into arc-shaped and irregular structures, with the surface treated by sandblasting and mirror finish, applied to the glass curtain wall supports of commercial buildings around the Dubai Burj Khalifa and the handrail railings of shopping malls in Paris’ Champs-Élysées, combining modernity with anti-aging properties.
Public facilities: Functional components of subways and stadiums in North America and Australia. Colored stainless steel plates (such as rose gold, bronze color) are treated with PVD coating, resistant to fingerprints and UV rays, applied to the waiting pavilions of New York subway stations and the seat supports of the Melbourne Stadium in Australia, enhancing the visual texture and service life of public spaces.
Overseas market adaptation strategy​
Regional customization: For high-corrosion areas (such as the Middle East and coastal countries), we promote 316L MOD and 904L products; for ordinary industrial scenarios (such as inland Europe), we provide 304 and Q235 stainless steel combination solutions.​
Service support: Provide cutting, bending, welding and other one-stop processing services, cooperate with overseas warehouses (Düsseldorf in Europe, Houston in North America, Singapore in Southeast Asia) to achieve 72-hour rapid delivery, meeting customers’ urgent project needs.​
Certification guarantee: All series of products are certified by international standards such as ASTM, EN, and JIS. Some products additionally obtain FDA and PED certifications, helping customers quickly pass local market entry audits.
