1. Chemical Composition

The chemical composition of grade 2205 stainless steel is outlined in the following table.

2. Physical Properties

The following table shows the physical properties of grade 2205 stainless steel.

3. Mechanical Properties

The mechanical properties of grade 2205 stainless steel are displayed in the following table.

4. DUPLEX APPLICATIONS

(1). Chemical processing, transport and storage,

(2). Oil and Gas exploration and processing equipment,

(3). Marine and other high chloride environments,

(4). Pulp and paper digesters, liquor tanks and paper machines.

5. Fabrication and Heat Treatment

(1). Annealing

Grade 2205 stainless steel is annealed at 1020-1070°C (1868-1958°F) and then water quenched.

(2). Hot Working

Grade 2205 stainless steel is hot worked in the temperature range of 954-1149°C (1750-2100°F). Hot working of this grade stainless steel under room temperature is recommended whenever possible.

(3). Welding

Welding methods recommended for grade 2205 stainless steel include SMAW, MIG, TIG and manual covered electrode methods. During the welding process, the material should be cooled below 149°C (300°F) between passes and preheating of the weld piece should be avoided. Low heat inputs should be used for welding grade 2205 stainless steel.

(4). Forming

Grade 2205 stainless steel is difficult to form due to its high strength and work hardening rate.

(5). Machinability

Grade 2205 stainless steel can be machined with either carbide or high speed tooling. The speed is reduced by about 20% when carbide tooling is used.

Huitong Group was established in 1978. After 38 years'development and innovation,by now,Huitong Group has set up multiple subsidiary companies.Among them,Zhengzhou Huitong Pipe Fitting Co.,Ltd.,with the indepent right of import and export, is mainly engaged in exporting steel pipe and pipe fittings for Huitong Group and assisting another subsidiary company of Huitong Group:Zhengzhou Huitong Machanical Equipment Co.,Ltd., in exporting machanical equipment.

Zhengzhou Huitong Pipeline Equipment Co.,Ltd.,with the strong support of Huitong Group,and years'development and innovation, are more and more professional in technical service and can manufacure products with all kinds of material,shape and size.
