Hardness: 70-90 HRB (adjustable via heat treatment)

Flatness: ≤0.5mm/m (laser-leveled for stamping dies)

🔹 Surface Excellence

Roughness: Ra ≤0.6μm (electropolishing optional)

Anti-Corrosion: Passivation coating (ASTM A967 compliant)

Manufacturing Excellence

Triple-Refined Smelting

Vacuum induction melting + argon shielding to minimize inclusions (<0.1% porosity).

Nanoscale Rolling

20-stage cold rolling with tension control (surface waviness <0.03mm).

Smart Annealing

Hydrogen atmosphere annealing for decarburization control (C loss <0.002%).

Precision Machining Advantages
