01 Four Core Product Categories Enter the High-End Global Market
From offshore engineering to energy transportation, from wind power infrastructure to high-end equipment manufacturing, Jingye Steel’s four core categories of medium and heavy plate products have successfully overcome key technical challenges such as extra-thick plate dimensional control and stable low-temperature toughness. These achievements have enabled Jingye Steel to enter the ranks of global high-end plate suppliers, providing critical materials for major industrial projects worldwide.
Shipbuilding & Offshore Engineering Steel
Full specification coverage for advanced marine applications
With the rapid development of global shipping and offshore engineering industries, higher demands have been placed on plate steel in terms of specification diversity, performance stability, and weldability.
In response, Jingye Steel has successfully developed shipbuilding steel products covering:
- Thickness: 5–120 mm
- Width: 1,000–4,700 mm
- Length: 2,000–25,043 mm
During development, Jingye Steel overcame challenges such as shape control of thin and wide plates, surface quality and performance control of thick and wide plates, cutting deformation of narrow and short plates, and logistics handling—demonstrating strong market responsiveness and service-oriented manufacturing capability.
Additionally, the EH40 series shipbuilding plates with 200 kJ/cm and 400 kJ/cm high heat input welding performance achieve excellent low-temperature impact toughness and weldability through precise control of phosphorus, sulfur, carbon, and nitrogen content, as well as effective elimination of internal defects in extra-thick slabs.
Wind Power & Bridge Steel
High toughness and weather resistance for major infrastructure
To meet the expanding demands of wind power projects in extreme environments and the performance upgrades required for bridge construction, Jingye Steel has developed a range of high-end wind power and bridge steels.
- Q420NE wind power steel, featuring high fatigue resistance and excellent weldability, addresses cracking issues commonly associated with high-strength welding by controlling carbon equivalent. It has been successfully applied in projects such as Goldwind’s green hydrogen demonstration project and projects in Dongsheng, Ordos.
- Q420ME wind power steel, capable of maintaining required mechanical properties after heating at 750°C and delivering reliable -50°C impact performance, effectively reduces safety risks for wind towers. It has been applied in the Shanghai Electric Daqing Oilfield project
Pressure Vessel & Pipeline Steel
Designed for extreme service conditions
For oil and gas pipelines and pressure vessels operating under harsh conditions, Jingye Steel’s R&D team focuses on low-temperature resistance, corrosion resistance, and high toughness.
- X70M pipeline steel resolves impact toughness limitations in thick-wall, large-diameter, high-grade pipelines. Through high reduction rolling and ultra-fast cooling technology, the product achieves an average -35°C impact energy of 300 J, and has been successfully used in natural gas pipeline projects in the UAE.
- L450MOS subsea pipeline steel meets HIC and SSCC resistance requirements through refining and vacuum treatment, strict continuous casting control, and optimized slab quality. It has been successfully applied in domestic subsea pipeline projects.
- 9% Ni low-temperature steel overcomes challenges in precise nickel alloying and stable toughness control, maintaining excellent performance at -196°C, providing a localized material solution for LNG storage tanks and other cryogenic equipment.
Construction Machinery Steel
Superior strength and toughness for heavy-duty applications
To address toughness challenges in extra-thick high-strength plates, Jingye Steel optimized rolling and cooling temperature control, achieving industry-leading process capability. This enabled the successful development of S460M-Z35 ultra-thick plates (100–150 mm), which have been applied in high-rise construction projects in Ras Al Khaimah, Middle East.
In parallel, Q1100E ultra-high-strength steel adopts optimized chemical composition and quenching & tempering processes to balance strength and toughness, offering excellent weldability and marking Jingye Steel’s advancement to a domestically leading level in ultra-high-strength plate production.
02 Advanced Cold-Rolled Products Empower High-End Manufacturing
Jingye Steel has established a 2.6 million ton/year cold-rolling and coating production base, producing:
- Cold hard coil
- Cold rolled coil
- Galvanized steel
- Galvalume steel
- Zn-Al-Mg coated steel
- Pre-painted steel
These products are widely used in high-end construction materials, home appliances, hardware, automotive structural parts, and stamping components.
Key breakthroughs include:
- Successful trial production of 0.20–0.25 mm ultra-thin hard-rolled coils
- Mass production of HC330/590DPD+Z galvanized dual-phase steel
- Large-scale production of JY1500HS automotive steel
For ultra-thin gauges, Jingye Steel addressed common industry challenges such as strip breakage through strict raw material control, process optimization, and stable operation, meeting international market requirements and supporting tinplate, tinning, and galvanizing applications.
In automotive steel, JY1500HS achieves high tensile strength and improved weldability through optimized weld heat treatment and full-process technical control. The product supports hot stamping technology, enabling complex part forming in a single step while reducing downstream processing costs.
Meanwhile, HC330/590DPD+Z galvanized dual-phase steel achieves an optimal balance between performance and cost by simplifying alloy composition and precisely matching galvanizing cooling rates, enhancing market competitiveness and expanding Jingye Steel’s dual-phase steel portfolio.
03 Customer-Oriented Product Upgrading and Service Transformation
While achieving breakthroughs in key product technologies, Jingye Steel continues to advance a customer-centric strategy, positioning high-grade steel development and transformation toward manufacturing services as long-term objectives.
The Medium & Heavy Plate Division has made solid progress in value-added services, including CNC cutting of small plates, ship plate pre-treatment, and modular/complete delivery solutions, evolving from steel production to material solution provision.
Driven by both technology development and market access, Jingye Steel has successfully developed new products such as NM450, and has been shortlisted as a qualified supplier for global clients including Shanghai Electric and General Electric.
Jingye Steel Research Institute promotes early supplier involvement (EVI) by embedding technical teams into customer production lines, jointly solving process challenges through tailored material development and lifecycle technical support. This approach has successfully resolved production issues for radiator fittings and new energy vehicle stamping, earning strong customer recognition and improving production efficiency.
