2507 duplex stainless steel pipe
Specific gravity and application field of 2507 duplex stainless steel pipe
The specific gravity of 2507 duplex stainless steel pipe is 8.03g/cm3 .
AISI 2507 ( UNS S32750 ) duplex stainless steel has strong strength and corrosion resistance. It is mainly used in chemical processing, petrochemical industry and submarine equipment. It has strong chloride corrosion resistance, high thermal conductivity and low coefficient of thermal expansion. High content of chromium, molybdenum and nitrogen. It has high resistance to spot corrosion, crack corrosion and general corrosion. Its impact strength is also very high. 2507 alloy is not suitable to be used in the temperature environment higher than 570 ℃. Its toughness will be reduced in such environment for a long time.
Super duplex stainless steel 2507 ( S32750 ) has higher corrosion resistance and better mechanical properties than duplex stainless steel 2205 (S31803). It is often used in special chemical environment equipment such as offshore oil platform ( 2507 duplex steel heat exchanger pipe , water treatment and water supply system, fire protection system, sprinkler system and water stabilization system), desalination (Desalination) equipment (high-pressure pipe and seawater pipe in RO equipment). Name: AISI 2507 , UNS S32750 , SAF2507, F53 , Chiness GB standard: 00Cr25Ni7Mo4N. there have 2507 pipe fittings , and 2507 flange
The application fields of 2507 duplex stainless steel pipe are: Petroleum and natural gas industrial equipment; Offshore platform, heat exchanger, underwater equipment and fire fighting equipment; Chemical processing industry, utensils and pipelines; Desalination plants and submarine pipelines; Mechanical parts (high-strength and corrosion-resistant parts), energy industry FGD system, industrial washing system, absorption tower, etc.
