Duplex Stainless Steel 2205 Properties

With high speed steel tooling 2205 duplex stainless steel plate may be machined at the same feeds and speeds as alloy 316l.

Duplex stainless steel 2205 properties.

If embrittled this can only be rectified by a full solution annealing treatment. Although 2205 has good high temperature oxidation resistance this grade like other duplex stainless steels suffers from embrittlement if held for even short times at temperatures above 300 o c. Their microstructures consist of a mixture of austenite and ferrite phases. Pulp and paper industry.

Yield strength 0 2 proof mpa min. 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. Rockwell c hr c brinell. Tensile str mpa min.

Oil and gas extraction and processing. Established in 1981 iso 9001 certified co. When carbide tooling is used cutting speeds should be reduced by about 20 relative to the speeds for alloy 316l. The name 2205 comes from a typical.

For optimum corrosion resistance surfaces must be free of scale and foreign particles. 2205 is annealed at 1020 1100 o c followed by rapid cooling. Table 2 mechanical properties of 2205 grade stainless steels. Duplex 2205 is a two phase ferritic austenitic 22 chromium 3 molybdenum 5 to 6 nickel alloyed stainless steel.

Duplex 2205 stainless steel both ferritic and austenitic is used extensively in applications that require good corrosion resistance and strength. Chemical processing storage and transport. 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. Elongation in 50mm min.

As a result duplex stainless steels display properties characteristic of both austenitic and ferritic stainless stee ls. Due to excellent corrosion resistance and high strength the most widely used duplex stainless steel is 2205.
