Duplex Stainless Steel 2205 Properties

The name 2205 comes from a typical.

Duplex stainless steel 2205 properties.

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. Pulp and paper industry. Duplex 2205 stainless steel both ferritic and austenitic is used extensively in applications that require good corrosion resistance and strength. Iso 14001 certified co.

Table 2 mechanical properties of 2205 grade stainless steels. With high speed steel tooling 2205 duplex stainless steel plate may be machined at the same feeds and speeds as alloy 316l. Established in 1981 iso 9001 certified co. 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.

For optimum corrosion resistance surfaces must be free of scale and foreign particles. As a result duplex stainless steels display properties characteristic of both austenitic and ferritic stainless stee ls. Chemical processing storage and transport. Rockwell c hr c brinell.

Ohsas 18001 certified co. When carbide tooling is used cutting speeds should be reduced by about 20 relative to the speeds for alloy 316l. Yield strength 0 2 proof mpa min. Tensile str 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. Duplex 2205 is a two phase ferritic austenitic 22 chromium 3 molybdenum 5 to 6 nickel alloyed stainless steel. Due to excellent corrosion resistance and high strength the most widely used duplex stainless steel is 2205. If embrittled this can only be rectified by a full solution annealing treatment.

Their microstructures consist of a mixture of austenite and ferrite phases. Oil and gas extraction and processing.
