3.3 Customized Material
We can customize steel billets of other material models (such as alloy structural steel, boiler steel, etc.) according to customer-specific needs. The chemical composition can be adjusted according to customer requirements, providing personalized material solutions to meet the needs of different scenarios.
4. Production Process
Continuous Casting → Soaking Heating → High-pressure Rolling → Controlled Cooling → Finishing → Inspection → Packing & Warehousing
Advanced continuous casting process is adopted to reduce internal defects of steel billets and ensure uniform distribution of chemical composition; temperature-controlled cooling is carried out throughout the process to ensure stable mechanical properties of steel billets, and each process is professionally tested to prevent unqualified products from leaving the factory.
