2205 Duplex Stainless Steel Excellent Yield Strength For Heat exchanger and cold shower

Product decribe:

Duplex stainless steel refers to ferrite and austenite about 50% each, generally less phase content at least also need

to reach 30% of stainless steel.When the content of C is low, the content of Cr and Ni ranges from 18% to 28% and 3%

to 10% respectively.Some steels also contain alloying elements such as Mo, Cu, Nb, Ti and N.Duplex stainless steel has

developed into the third generation since its birth in the United States in the 1940s.Its main characteristic is the yield

strength can reach 400-550mpa, is the ordinary stainless steel 2 times, therefore can save material, reduce the equipment

manufacturing cost.In the aspect of corrosion resistance, especially under the condition of harsh medium environment

(such as seawater, high chloride ion content), the anti-pitting corrosion, crevice corrosion, stress corrosion and corrosion

fatigue performance of duplex stainless steel is obviously better than ordinary austenitic stainless steel, which can be

comparable with high-alloy austenitic stainless steel.

Duplex stainless steel characteristics:

(1) Molybdenum - containing duplex stainless steel has good chloride stress corrosion resistance under low stress.

Generally, 18-8 type austenitic stainless steel is prone to stress corrosion fracture in neutral chloride solution above

60° C. Heat exchangers, evaporators and other equipment manufactured with such stainless steel in trace chloride

and hydrogen sulfide industrial medium have the tendency to produce stress corrosion fracture, while duplex stainless

steel has good resistance.

(2) Molybdenum - containing duplex stainless steel has good corrosion resistance.The critical pore corrosion potential

of duplex stainless steel and austenitic stainless steel is similar when the quantity value (PRE=Cr%+3.3Mo%+16N%)

has the same pore corrosion resistance.The corrosion resistance of duplex stainless steel and austenitic stainless steel

is comparable to AISI 316L.The resistance to pore corrosion and crevices of high chromium duplex stainless steel

containing 25%Cr, especially nitrogen, exceeds AISI 316L.

(3) Have good corrosion resistance fatigue and wear corrosion performance.In some corrosive medium conditions,

suitable for the manufacture of pumps, valves and other power equipment.

(4) Good comprehensive mechanical properties.It has high strength and fatigue strength. The yield strength is twice that

of type 18-8 austenitic stainless steel.The elongation of solid solution state reaches 25%, and the toughness value AK

(V-notch) is above 100J.

(5) Good weldability, small hot crack tendency, generally do not need preheating before welding, after welding does not

need heat treatment, can with 18-8 type austenitic stainless steel or carbon steel and other different welding.

(6) Dual-phase stainless steel with low chromium (18%Cr) has a wider thermal processing temperature range than 18-8

type Austenitic stainless steel with less resistance. It can be rolled directly to produce steel plates without forging.Biphasic

stainless steels with high chromium content (25%Cr) are slightly more difficult to process than austenitic stainless steels

and can be used to produce products such as plates, tubes and wires.

(7) The working hardening effect of 18-8 type austenitic stainless steel during cold working is larger than that of 18-8 type

austenitic stainless steel. In the initial stage of tube and plate bearing deformation, greater stress should be applied to


(8) Compared with austenitic stainless steel, the thermal conductivity is large, the coefficient of linear expansion is small,

suitable for the lining of equipment and production of composite board.Also suitable for the manufacture of heat exchanger

core, heat transfer efficiency is higher than austenitic stainless steel.

(9) There are still various brittleness tendencies of high chromium ferritic stainless steel and should not be used in working

conditions higher than 300°C.The lower the chromium content of a duplex stainless steel, the less harmful the brittle phase

such as is.
