What's the difference between 2205 and 2507?
The standard of duplex stainless steel 2205 is ASTM A240.
Duplex stainless steel 2205 alloy is a duplex stainless steel composed of 22% chromium, 2.5% molybdenum and 4.5% nickel-nitrogen alloy.
It has high strength, good impact toughness and good overall and local stress corrosion resistance.
2507 (UNS S32750) super duplex stainless steel is composed of 25% chromium, 4% molybdenum and 7% nickel.
It has strong strength and corrosion resistance, and is mainly used in chemical processing, petrochemical and sea equipment.
It has strong resistance to chloride corrosion, high thermal conductivity and low thermal expansion coefficient.
The high content of chromium, molybdenum and nitrogen makes it highly resistant to pitting corrosion, crevice corrosion and uniform corrosion.
The 2205 and 2507 stainless steel bar has become an important engineering material during past decades.
2507 Stainless Steel Bar Applications:
1) Petrochemical equipment
2) Offshore oil platform (heat exchanger pipe, water treatment and water supply system, fire protection system, sprinkler system, water stabilization system)
3) Mechanical and structural components requiring both high strength and high corrosion resistance
4) Desalination (desalination) equipment (and the high-pressure pipe and seawater pipe in the equipment)
5) Burning (waste) gas purification equipment.
