Tooling & Mold Manufacturing

The base develops and produces high-isotropy, long-life mold steels, high-polishability and corrosion-resistant mirror-finish mold steels, ultra-hard and wear-resistant mold materials, powder metallurgy steels, and large-scale three-way equal toughness mold steels according to universal standards and customer requirements.

Our portfolio includes super high-speed steels and specialized cutting tool steels for extra-large tunnel boring machines (TBM). We offer long-life super hot-work mold steels featuring excellent thermal strength, plasticity, fatigue resistance, and conductivity at high temperatures, as well as cold-work mold steels that achieve an optimal balance of plasticity, wear resistance, and compressive strength.

Petrochemical & Energy Sector

Our product range for the petrochemical and energy sectors includes high-corrosion-resistant super stainless steels, high-formability steels, heat- and oxidation-resistant alloys, high-nitrogen stainless steels, and materials for large-scale fertilizer equipment.
We specialize in special stainless steels for ultra-low temperature pressure vessels, nanocrystalline (single crystal) steels, ultra-high strength steels with high fracture toughness, and anti-bio-corrosion materials for marine engineering. Our high-strength non-magnetic steels for deep-sea drilling and special steels for cryogenic deep-well valve bodies are widely utilized in nuclear power, oil & gas, chemical processing, aerospace, marine engineering, machinery, and medical sectors.
