S32205 Duplex Stainless steel forged bar is a very popular steel bar by customer, it will choose excellent stainless steel raw material and be forged.

S32205=AISI 2205 =F60 

Its main chemical specification is as following :

Cr :22~23%

Ni:4.5~6.5% 

Mo:3.0-3.5%

N:0.14~0.2%

Its main  property :

Mechanical property 

The mechanical properties of S32205 include high yield strength and good ductility.

 Its dual phase microstructure helps to improve its resistance to stress corrosion cracking, 

and in environments containing chlorides, the use of S32205 is less restricted compared to

 austenitic stainless steels such as 304L, 316L, and 317L.

Heat treatment system

S32205 typically does not require heat treatment to achieve the desired performance. 

But if it is necessary to change its microstructure to optimize performance, appropriate 

heat treatment can be carried out.

Application area

S32205 is widely used in fields such as chemical engineering, petroleum, marine engineering,

 and food processing. It can be used to manufacture equipment and pipelines in high temperature, 

high pressure, and highly corrosive environments; In the petroleum industry, it can be used to 

manufacture oil well pipelines and offshore oil and gas platforms; In the field of ocean engineering, 

it can be used to manufacture seawater treatment equipment and ship structural components; In 

the field of food processing, it can be used to manufacture food containers and conveying equipment.

Corrosion resistance

The corrosion resistance of S32205 is attributed to its chemical composition and crystal structure 

characteristics. It has high thermal stability and oxidation resistance, and can maintain good 

performance in high temperature and acid-base environments. In addition, S32205 has a lower

 corrosion rate and higher resistance to stress corrosion, making it suitable for engineering in 

corrosive environments.

Weldability

S32205 duplex stainless steel has good weldability, but attention should be paid to controlling 

welding parameters during the welding process to avoid the precipitation of harmful metal 

phases, which may affect the performance of the material.

Polishing performance

S32205 can be easily polished to achieve a high gloss surface effect.

Heat resistance performance

S32205 maintains good mechanical properties even at continuous operating temperatures up 

to 200 ° C, making it suitable for high-temperature working environments.
