Material Characteristics:
Most metals and alloys expand in volume when heated and contract in volume when cooled. However, due to its [SCALE STEEL]ferromagnetism, the Inwatt alloy has abnormal thermal expansion in a certain temperature range, and its expansion coefficient is extremely low, sometimes even zero or negative.Its characteristics are summarized as follows:
(1) Small coefficient of expansion
The average expansion coefficient of Inwa alloy is generally 1.5×10-6/℃, and the volume does not change at room temperature [SCALE STEEL]from -80℃ to +100℃.  
(2) They were not strong
The carbon content of the alloy is less than 0.05%, the hardness and strength is not high, the tensile strength is about 517MPa, [SCALE STEEL]the yield strength is about 276MPa, the Vickers hardness is about 160, generally can be through cold deformation to improve the strength, in the strength is improved at the same time still has good plasticity.
(3) Low thermal conductivity
The thermal conductivity of [SCALE STEEL]watt alloys is 10W/m·K, only one-third of the thermal conductivity of 45 steel.  
(4) High plasticity and toughness
The ductility, toughness, elongation, reduction of section and impact toughness are all very high. The elongation is [SCALE STEEL]δ=30~45% and the shrinkage is δ=50~70%.Impact toughness αK=130~310 J/cm2.  
(5) Variations of other properties
Because of the high nickel content in the Intile alloy, the hardenability and quenchability of the steel are improved, and the gas resistance, corrosion resistance and wear resistance of the steel are improved.

Applications:
4j36 due to the advantages of low expansion, is indispensable to precision instrument structure material, it is widely used in electronics industry and precision instrument industry and other areas that are sensitive [SCALE STEEL]to size requirements, such as: double metal materials, magnetic materials, measuring instruments with fixture, astronomical telescope components, optical instruments, CFRP with metal molds, antenna parts, FPD with shielding framework, high precision printing in framework, and semiconductor with a check by machining fixture, semiconductor, etc.

Corrosion Resistance:
The 825 is resistant to corrosion in a variety of processing environments, including sulfuric acid, sulfurous acid, phosphoric acid, nitric acid, hydrofluoric acid, organic acid and alkali such as sodium, potassium hydroxide, acid [SCALE STEEL]chloride, etc.
Compared with ordinary austenitic stainless steels, the nickel in alloy 825 makes it resistant to chloride stress corrosion, while molybdenum and copper make it highly resistant to corrosion in reduced environments.Chromium and molybdenum are resistant to chloride pitting and corrosion in various oxidizing environments.The addition of titanium makes the material more stable and less susceptible to sensitization [SCALE STEEL]during welding.This insensitive property allows the material to resist intergranular corrosion even when exposed to the sensitive temperature range.
 
Mechanical Properties Of:
825 alloy has good mechanical properties in low and medium temperature environments.At 540°C, the microstructure of[SCALE STEEL] the material will change and the ductility and impact strength will decrease significantly. Therefore, it is not suitable for applications where creep fracture resistance is a design factor.
Alloy 825 can be fully strengthened by cold working.Has good impact strength at room temperature and can maintain this strength at low temperatures.
 
Applications:
As a typical nickel-based alloy, 825 alloy is easy to be formed and welded through technical processing.Application occasions [SCALE STEEL]for petroleum exploitation, chemical equipment, such as heat exchanger and condenser;Components used in sulfuric acid environment and acid gas containing a variety of ions;Pipelines and coolers for oil and steam;Nuclear waste disposal plant.

(1) Excellent resistance to various corrosive media under oxidation and reduction conditions;It is one of the few materials that can resist the corrosion of moist chlorine gas, hypochlorite and chlorine dioxide solution, and has[SCALE STEEL] significant corrosion resistance to high concentration of salt chloride solution (such as ferric chloride and copper chloride).
(2) It can also resist a variety of corrosive [SCALE STEEL]environments at a high temperature of up to 677℃.
(3)Good resistance to pitting corrosion, crevice corrosion and stress corrosion cracking.
(4) Excellent welding performance.

Applications:
Hastelloy C-22 alloy has been widely used in chemical and petrochemical fields, such as the application in the contact with chloride-containing organic components and catalytic systems.This material is especially suitable for high temperature, mixed with impurities of inorganic acids and organic acids (such as formic acid and acetic acid), sea water corrosion environment.
