S31603 316L Duplex Stainless Steel have superplastic alloy stainless steel

Product decribe:

Duplex stainless steel is in its solution in the ferrite phase and austenite about half, the general amount of less phase

content also need to reach 30%.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.This kind of steel

has the characteristics of austenite and ferritic stainless steel. Compared with ferritic steel, it has higher plasticity and

toughness, no room temperature brittleness, and significantly improved intergranular corrosion resistance and welding

performance. Meanwhile, it also has the characteristics of 475℃ brittleness, high thermal conductivity and superplasticity.

Compared with austenitic stainless steel, its strength is higher and its resistance to intercrystalline corrosion and chloride

stress corrosion is improved obviously.Duplex stainless steel has excellent corrosion resistance and is also a

nickel - saving 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.

Compared with austenitic stainless steel, the advantages of duplex stainless steel are as follows:

(1) The yield strength is more than twice as high as that of ordinary austenitic stainless steel, and has sufficient plastic

toughness required for molding.The wall thickness of storage tanks or pressure vessels made of duplex stainless steel is

30-50% less than that of commonly used austenite, which is beneficial to cost reduction.

(2) Excellent stress corrosion cracking resistance, even the lowest alloy duplex stainless steel has a higher stress corrosion

cracking resistance than austenitic stainless steel, especially in the environment containing chlorine ions.Stress corrosion

is an outstanding problem of ordinary austenitic stainless steel.

(3) In many media, the most common application of 2205 duplex stainless steel corrosion resistance is better than ordinary

316L austenitic stainless steel, and super duplex stainless steel has very high corrosion resistance, and some media, such

as acetic acid, formic acid and so on can even replace high alloy austenitic stainless steel, and corrosion resistance alloy.

(4) Has a good local corrosion resistance, compared with the alloy content of austenitic stainless steel, its wear resistance

and fatigue corrosion performance are better than austenitic stainless steel.

(5) Lower than austenitic stainless steel linear expansion coefficient, and carbon steel, suitable for carbon steel connection,

has important engineering significance, such as the production of composite board or lining.

(6) No matter under dynamic or static load, austenitic stainless steel has a higher energy absorption capacity than austenitic

stainless steel, which has obvious advantages for structural parts to deal with sudden accidents such as collision, explosion,
