For optimum corrosion resistance surfaces must be free of scale and foreign particles. It is the most widely used duplex stainless steel grade and is characterized by high yield strength double that of the standard austenitic stainless steel grades. Due to excellent corrosion resistance and high strength the most widely used duplex stainless steel is 2205. Chemical processing storage and transport.

When carbide tooling is used cutting speeds should be reduced by about 20 relative to the speeds for alloy 316l. Elongation in 50mm min. With high speed steel tooling 2205 duplex stainless steel plate may be machined at the same feeds and speeds as alloy 316l. Yield strength 0 2 proof mpa min.

Tensile str mpa min. If embrittled this can only be rectified by a full solution annealing treatment. 2205 has better fatigue strength in corrosive environments than the standard austenitic stainless steel grades due to its higher strength and higher corrosion resistance n b. Duplex 2205 stainless steel both ferritic and austenitic is used extensively in applications that require good corrosion resistance and strength.

As a result duplex stainless steels display properties characteristic of both austenitic and ferritic stainless stee ls. Iso 14001 certified co. 2205 is annealed at 1020 1100 o c followed by rapid cooling. Powerful machines and rigid mounting of tools and parts are essential.

The name 2205 comes from a typical. Oil and gas extraction and processing.
