Quick Detail
2507 super duplex stainless steel has become an important engineering material. With the continuous expansion of duplex stainless steel applications, 2507 super duplex stainless steel forged ring is widely used in petrochemical, offshore and coastal facilities, oilfield equipment, papermaking, shipbuilding and environmental protection.
Description
2507 super duplex stainless steel is a ferritic-austenitic (duplex) stainless steel with excellent resistance to pitting corrosion, crevice corrosion and uniform corrosion. 2507 super duplex stainless steel is used in the oil and natural gas industry; offshore rock-breaking oil platforms (heat exchanger tubes, water treatment and water supply systems, fire fighting systems, water spray systems, water stabilization systems; petrochemical equipment; desalination (desalination) equipment ( And the high-pressure pipes and seawater pipes in the equipment); machinery and structural parts that require both high strength and high corrosion resistance; combustion (waste) gas purification equipment.
