Product Description

Duplex Stainless Steel (DSS) describes approximately 50% of ferrite and austenite and Steels also contain alloying elements such as Mo, Cu, Nb, Ti, and N. Content, the Cr content is 18% to 28 percent, and the Ni content is 3% to 10%. Some Contains less than 30 percent of stainless steel. In the case of diminished C


This type of steel unites the characteristics of ferritic and austenitic stainless steels. In comparison with ferrite, it has higher plasticity and toughness, no brittleness at room temperature to intergranular corrosion and welding functionality, and in the same time retains iron. The 475 brittleness and high thermal conductivity of the stainless steel make it superplastic. Compared with austenitic stainless steels, they have high durability and resistance to chloride stress corrosion resistance and intergranular corrosion. Duplex stainless steel has corrosion resistance and is also a nickel-saving stainless steel.

Production Process and Feature

Duplex stainless steel has the qualities of austenitic stainless steel and stainless steel since it has ferritic structure as well as the are essentially exactly the same. The yield strength can attain 400Mpa 550MPa, which can be that of austenitic stainless steel. In comparison with ferritic stainless steel, duplex stainless steel has high toughness transition temperature, and resistance to intergranular corrosion and reliability. At precisely the exact same time, it keeps some features of ferritic stainless steel, for example as 475 brittleness and warmth. Conductivity, properties, superplasticity and little growth coefficient. In comparison with stainless steel, the potency of duplex stainless steel is high the yield strength is enhanced, along with the properties like pressure corrosion resistance, corrosion resistance and corrosion fatigue resistance are enhanced.


Duplex stainless steels are classified according to their chemical composition and can be classified into four types: Cr18 kind, Cr23 (excluding Mo) kind, Cr22 type and Cr25 type. For Cr25 kind duplex stainless steel, it can be divided into form and super duplex stainless steel. Among these, Cr22 kind and Cr25 type are utilized. The duplex stainless steel used in China is produced in Sweden. The specific grades are: 3RE60 (Cr18 kind ), SAF2304 (Cr23 type), SAF2507 (Cr22 kind ), SAF2507 (Cr25 type).


2205/2507 duplex stainless steel performance characteristics

On account of the qualities of this two-phase structure, the duplex stainless steel has the benefits of ferritic stainless steel and austenitic stainless steel by properly controlling the chemical composition and heat treatment procedure, and it will have exceptional toughness and weldability with austenitic stainless steel and iron. High resistance and strength of tempered stainless steel


The combo of chloride stress corrosion properties, these properties create duplex stainless steel grow as a structural material. Since the 1980s, it has come to be a parallel using ferritic, austenitic and martensitic stainless steels. Steel. Duplex stainless steel has the following performance features:


(1) Molybdenum-containing duplex stainless steel has great resistance to chloride stress corrosion under stress that is reduced. Ordinarily, 18-8 types austenitic stainless steel is more prone to stress corrosion cracking in neutral chloride alternative over 60 °C, and heat exchangers, evaporators, etc. created of these stainless steel in industrial moderate of follow chromium and hydrogen sulfide. A propensity is to generate stress corrosion cracking, whilst duplex stainless steel has great immunity.


(2) Molybdenum-containing duplex stainless steel has resistance that is pitting. The duplex pitting potential of this duplex stainless steel is comparable to that of the austenitic stainless steel as it has exactly the exact same pitting resistance equivalent worth (PRE=Crpercent +3.3Mopercent +16Npercent ). The corrosion resistance of duplex stainless steel and stainless steel is similar to that of AISI 316L. The corrosion resistance of 25 percent Cr-containing, particularly high-chromium duplex stainless steels surpasses that of AISI 316L.


(3) It's good corrosion fatigue and wear corrosion resistance. In certain corrosive media's case, it is acceptable for producing electricity equipment such as pumps and valves.


(4) Has fatigue durability and high strength, and its yield strength is that of 18-8 austenitic stainless steel. The elongation from the solution condition is The comprehensive properties are great. It 25%, and the toughness value AK (V-notch) are above 100J.


(5) Fantastic solderability, cracking tendency that is non no preheating after welding, and may be welded to 18-8 kind austenitic stainless steel or carbon steel.


(6) The duplex processing temperature of the duplex stainless steel comprising low chromium (18% Cr) is wider than that of those 18-8 austenitic stainless steel, and the resistance is modest, and the steel sheet could be straight rolled and wrapped without repainting. The sexy processing of duplex stainless steels containing high chromium (25% Cr) is marginally more challenging compared to austenitic stainless steels, also may be used to create plates, wires and tubes.


(7) Compared with 18-8 type austenitic stainless steel through cold working, the work hardening effect is big. After the tube and the plate are subjected to deformation, big stress is required to deform.


(8) In Comparison with stainless steel, it's a Appropriate for creating panels and for use as a liner for gear. For creating heat exchanger expires, heat transport efficiency is Acceptable A little along with thermal conductivity coefficient of growth, and is Greater than austenitic stainless steel.


(9) Stainless steel, which should not be used in working conditions above 300 °C. The reduced the chromium content in duplex stainless steel, the less harmful the brittle phase such as σ.

There are various Delicate tendencies of ferritic


Application

Heat exchangers and showers And apparatus for seawater, higher fever, concentrated nitric oxide, etc., for optimizing, fertilizer, paper, oil, chemical, etc..
