SUS316H Stainless Steel Plate & Coil: High-Carbon High-Temp Corrosion-Resistant Plate/Coil

What is SUS316H Stainless Steel Plate & Coil?

SUS316H is the high-carbon molybdenum-containing variant of SUS316, optimized for high-temperature creep strength. It integrates high-temperature stability and corrosion resistance, tailored for high-stress, high-temperature corrosive plates/coils.

Key Properties (20°C, Annealed, Horizontal)

Density: 7.98g/cm³ | Melting Point: 1375-1450°C | Tensile Strength: ≥515N/mm² | Yield Strength: ≥205N/mm² | Elongation: ≥40% | Hardness: ≤217HB

Core Characteristics

• High-carbon creep enhancement: Maintains structural stability at 600-870°C under long-term high stress, better than SUS316 • Molybdenum-enabled corrosion resistance: Resists high-temperature oxidation and chloride corrosion, suitable for harsh high-temp environments • Mandatory post-weld annealing: Ensures uniform structure and stable high-temperature performance • Specialized for high-end high-temperature piping: Suitable for power plant high-pressure corrosive plates and industrial furnace coils
