Description
G205/ 201A has extremely high strength, it also provides some advantages over G304 in certain structural applications. Presence of copper in this steel reduces work hardening rate and improves draw ability. Nitrogen improves resistance to printing corrosion. The alloy is nonmagnetic in annealed condition like G304. Thus G205 can display a wide range of mechanical strength depending on the degree of cold working, which is essential for certain structural applications.

Typical Applications
- AISI 205 is used in making utensils such as shallow or medium drawn utensils, tableware, cutlery,
- Stands for water filters and In-house water tanks.
- Consumer durables such as steel furniture, fruit stands, flower vases, decorative pipes and tubes,
- Gas stoves and gift items can be made from AISI 205.
- Architecture building and construction companies use AISI 205 to make in-house panels, hands rails, Structural support framework, door knobs, hinges and dust bins.
- AISI 205 can also be used to transport items via conveyors.
This Grade is not recommended for use for external purposes in coastal/ salty environment. It is also not recommended for handling/storage of acid and other highly corrosive industrial chemicals
