Precision Alloys have unique bodily and mechanical properties, and are thoroughly utilized in the essential elements and products of precision motor, electrical appliance, instruments and meters, telecommunication equipments, and precision machines.

In accordance to the application and specialties, precision alloys are break up into challenging magnetic alloy, magnetically comfortable alloy, elastic alloy, enlargement alloy, thermo bimetal, resistance alloy, thermocouple alloy, electric powered conduction alloy, electric powered contact alloy, form memory alloy, superconducting alloy and so on.

one. Description
 
Soft Magnetic Alloy is one kind of alloy with high permeability  and low coercivity in weak magnetic field. This kind of alloy is widely used in radio electronics industry, precision instruments, remote control and automatic control system, generally, it is mainly used in energy conversion and information processing.

Characteristic:
The higher focus of molybdenum,chromium and nitrogen created 254SMO has very excellent resistance to pitting and crevice corrosion functionality. Copper enhanced corrosion resistance in some of the acid . In addition, thanks to its substantial content of nickel,chromium and molybdenum, so that 254SMO have a good stress toughness corrosion cracking functionality.
1.A good deal of a vast variety use of expertise has proven that even iin increased temperatures, 254SMO in the sea drinking water is also extremely resistant to corrosion efficiency hole, only a few types of stainless steel with this overall performance.
two.254SMO such as bleach paper needed for the generation of acidic answer and the remedy halide oxidative corrosion resistance and corrosion resistance can be in comparison to the most resilient in the base alloy of nickel and titanium alloys.
3.254SMO thanks to a substantial nitrogen content, so its mechanical power than other types of austenitic stainless metal is larger. In addition, 254SMO also highly scalable and effect strength and good weldability.
four.254SMO with substantial molybdenum articles can make it higher rate of oxidation in the annealing , which following the acid cleaning with rough surface than standard stainless metal is a lot more common than the rough surface. Nevertheless,has not adversely afflicted for the corrosion resistance of this metal .
 
Metallurgical framework
254SMO is experience-centered cubic lattice structure. In buy to obtain austenitic construction, 254SMO common annealing in the 1150-1200ºC.In some cases, the materials maybe with the traces of metallic middle phase (χ section and α-section). Nevertheless,their impact energy and corrosion resistance are not adversely affected in typical circumstances. When put in the variety of 600-1000ºC, they might section in the grain boundary precipitation.
 
Corrosion resistance
254SMO with extremely reduced carbon articles, which means that the risk by the heating caused of carbide precipitation is extremely tiny. Even in the 600-1000ºC after one particular hour sensitization still capable to Strauss by way of the intergranular corrosion test (Strauss Test ASTMA262 get E).Nonetheless, since of the substantial-alloy steel content. In the previously mentioned-mentioned temperature variety intermetallic phase with the probability of steel in the grain boundary precipitation. These sediments do not make it arise intergranular corrosion in the corrosive media programs, then,welding can be carried out CZPT intergranular corrosion.But in the warmth of concentrated nitric acid, these sediments may possibly be caused intergranular corrosion in warmth-impacted zone. If regular stainless steel in the answer that containing chloride, bromide or iodide,it will show pitting, crevice corrosion or tension corrosion cracking type by localized corrosion. However, in some cases,the existence of halide will speed up the uniform corrosion. Especially in the non-oxidizing acid. In pure sulfuric acid, 254SMO with a much greater corrosion resistance than 316(common stainless steel),but with abated corrosion resistance in contrast to 904L (NO8904) stainless metal in higher concentrations. In the sulfuric acid that contains chloride ions , 254SMO with the greatest corrosion resistance potential.The 316 can not be utilized for stainless metal in hydrochloric acid given that it could arise localized corrosion and uniform corrosion, but 254SMO can be used in diluted hydrochloric acid in standard temperatures,uder the border region do not want to fear about corrosion transpired. Nonetheless, we should consider to avoid the gap cracks. In the fluoride silicate (H2SiF4) and hydrofluoric acid (HF), the corrosion resistance of ordinary stainless steel is quite constrained, and 254SMO can be employed in a quite wide temperature and concentration.
 
Applied field:254SMO is a mult-objective content can be employed in many industrial programs:
1. Petroleum, petrochemical gear, petro-chemical products, this sort of as the bellows. 
two. Pulp and paper bleaching gear, this kind of as pulp cooking, bleaching, washing filters used in the barrel and cylinder pressure rollers, and so on. 
3. Electrical power plant flue gas desulphurization equipment, the use of the principal components: the absorption tower, flue and halting plate, inner portion,spray method. 
four. At sea or sea water processing system, this sort of as power vegetation making use of sea drinking water to cool the skinny-walled Condenser, desalination of sea drinking water processing equipment,can be applied even however the h2o might not movement in the device.
five. Desalination industries, this kind of as salt or desalination gear. 
6. Warmth exchanger, in particular in the working setting of chloride ion.
