Duplex Stainless Steel Seamless Tube and Pipe S31803 S32205 S32750

Product Description

Introduction
Stainless steels are high-alloy steels. These steels are available in four groups that include martensitic, austenitic, ferritic and precipitation-hardened steels. These groups are formed based on the crystalline structure of stainless steels.
Stainless steels contain larger amounts of chromium in comparison with other steels and thus have good corrosion resistance. Most of the stainless steels contain about 10% of chromium.
Grade 2205 stainless steel is a duplex stainless steel whose design enables combining improved resistance to pitting, high strength, stress corrosion, crevice corrosion and cracking. Grade 2205 stainless steel resists sulfide stress corrosion and chloride environments.
The following datasheet provides an overview of grade 2205 stainless steel.

Annealing
Grade 2205 stainless steel is annealed at 1020-1070°C (1868-1958°F) and then water quenched.
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.
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.
Forming
Grade 2205 stainless steel is difficult to form due to its high strength and work hardening rate.
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.
Applications
Grade 2205 stainless steel is used in the following applications:
Flue gas filters
