Duplex Stainless Steel 2205 Properties

Iso 14001 certified co.

Duplex stainless steel 2205 properties.

Due to excellent corrosion resistance and high strength the most widely used duplex stainless steel is 2205. Yield strength 0 2 proof mpa min. Pulp and paper industry. 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.

For optimum corrosion resistance surfaces must be free of scale and foreign particles. Elongation in 50mm min. If embrittled this can only be rectified by a full solution annealing treatment. Rockwell c hr c brinell.

Table 2 mechanical properties of 2205 grade stainless steels. 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. Their microstructures consist of a mixture of austenite and ferrite phases.

Established in 1981 iso 9001 certified co. With high speed steel tooling 2205 duplex stainless steel plate may be machined at the same feeds and speeds as alloy 316l. The name 2205 comes from a typical. Ohsas 18001 certified co.

2205 is annealed at 1020 1100 o c followed by rapid cooling. As a result duplex stainless steels display properties characteristic of both austenitic and ferritic stainless stee ls. Tensile str mpa min. Duplex 2205 stainless steel both ferritic and austenitic is used extensively in applications that require good corrosion resistance and strength.

Powerful machines and rigid mounting of tools and parts are essential. 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.
