Duplex Stainless Steel 2205 Properties

2205 is annealed at 1020 1100 o c followed by rapid cooling.

Duplex stainless steel 2205 properties. Due to excellent corrosion resistance and high strength the most widely used duplex stainless steel is 2205. 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. 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.

Duplex 2205 is a two phase ferritic austenitic 22 chromium 3 molybdenum 5 to 6 nickel alloyed stainless steel. If embrittled this can only be rectified by a full solution annealing treatment. Table 2 mechanical properties of 2205 grade stainless steels. Established in 1981 iso 9001 certified co.

Powerful machines and rigid mounting of tools and parts are essential. Tensile str mpa min. Duplex 2205 stainless steel both ferritic and austenitic is used extensively in applications that require good corrosion resistance and strength. Pulp and paper industry.

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. When carbide tooling is used cutting speeds should be reduced by about 20 relative to the speeds for alloy 316l. 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. Oil and gas extraction and processing. Ohsas 18001 certified co. Elongation in 50mm min.

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. Their microstructures consist of a mixture of austenite and ferrite phases.
