15MnNiNbDR is a low-temperature pressure vessel steel plate developed for equipment operating under cold service conditions. It belongs to the nickel alloyed pressure vessel steel family and provides a good combination of strength, toughness and weldability.

With the addition of nickel, manganese and micro-alloying elements, 15MnNiNbDR offers improved low-temperature impact performance compared with conventional pressure vessel steels.

Key Features:

• Excellent low-temperature toughness
• Good weldability
• Stable mechanical properties
• Suitable for pressure-bearing equipment

Typical Applications:

• LPG storage tanks
• Low-temperature pressure vessels
• Chemical processing equipment
• Cryogenic-related equipment

15MnNiNbDR steel plate is commonly selected for pressure vessels where reliable performance at low temperatures is required.
