GB3531 09MnNiDR is a low-alloy steel plate designed for low-temperature pressure vessels, suitable for environments below -70°C. Due to its excellent low-temperature toughness and weldability, it is widely used in the following fields:
Pressure Vessel Manufacturing:
Used for producing low-temperature pressure vessels, such as liquefied petroleum gas (LPG) storage tanks, liquefied natural gas (LNG) storage tanks, ethylene storage tanks, liquid ammonia storage tanks, high-pressure nitrogen storage tanks, and carbon dioxide low-temperature storage tanks, widely applied in the petroleum, chemical, natural gas, and power industries.
Suitable for equipment like reactors, separators, and liquefied gas tanks that need to withstand low temperatures and high pressures.
Oil and Gas Industry:
Utilized in boilers, storage tanks, and heat exchangers for oil and gas projects, particularly in low-temperature environments (e.g., -28°C to -60°C) for manufacturing ammonia separators and carbon dioxide low-temperature storage tanks.
Infrastructure Construction:
Employed in the production of bridges, wind turbine towers, and other structural components requiring high strength and low-temperature corrosion resistance, due to its excellent strength-to-weight ratio and corrosion resistance.
Shipbuilding and Marine Engineering:
Applied in low-temperature pressure vessel components in the shipbuilding industry, suitable for marine environments due to its high strength and low-temperature performance.
Other Industrial Applications:
Used for manufacturing structural components that endure complex stresses and low-temperature conditions, such as low-temperature chemical equipment, refrigeration facilities, and low-temperature piping systems.
Suitable for cutting, welding, bending, and other processing to meet customized requirements, such as cold forming for producing cold-formed steel sections and welded pipes.
