Performance Characteristics
S32750 stainless steel has the following performance
characteristics:
Excellent corrosion resistance: High chromium, molybdenum and
nitrogen content give it excellent resistance to pitting, crevice
corrosion and general corrosion, especially in environments
containing chlorides.
High strength: Its yield strength is generally twice that of
austenitic stainless steel, which can meet some application
scenarios with high material strength requirements.
Good welding performance: It can be joined to itself or other
materials by a variety of welding methods, and no preheating is
required during welding.
Good resistance to chloride stress corrosion cracking: The duplex
structure gives it excellent resistance to chloride stress
corrosion cracking.
Good machinability and weldability: S32750 stainless steel has
good machinability and welding properties, and is suitable for
parts and components that require precision machining and welding.
Application areas
Due to its excellent comprehensive performance, S32750 stainless
steel is widely used in the following fields:
Petrochemical: Used to manufacture pipes, valves, pressure
vessels and other components in petrochemical equipment.
Chemical processing: Can be used to manufacture chemical
reactors, storage tanks, pipelines and other equipment.
Offshore and marine: Used for offshore platforms and equipment,
seawater desalination plants, seawater cooling heat exchangers,
etc.
S32750 Super Duplex Stainless Steel is a high-performance material
suitable for applications requiring high strength and excellent
corrosion resistance. Its wide application has proven its value in
the industrial field, especially in the oil, gas, chemical
processing and energy industries. With the development of
technology and the increase in demand for high-performance
materials, the application prospects of S32750 are promising.
