S31254/1.4547/254SMo Duplex Stainless Steel Description
    S31254/254SMo/1.4547 duplex stainless steel is an austenitic stainless steel. Because of its high molybdenum content, it has a very high resistance to corrosion and crevice corrosion resistance. This grade of stainless steel is developed and developed for use in environments containing halides such as seawater. S31254 duplex stainless steel also has good resistance to uniform corrosion. Especially in halide-containing acids, the steel is superior to ordinary stainless steel. Its C contains <0.03%, so called pure austenitic stainless steel (<0.01% also known as super austenitic stainless steel). Super stainless steel is a special kind of stainless steel, first in the chemical composition and ordinary stainless steel is different, refers to high nickel, high chromium, high molybdenum a high alloy stainless steel. Which is more famous is containing 6% Mo 254SMo, this kind of steel has a very good resistance to local corrosion, in the sea, inflatable, there is gap, low speed erosion conditions, good pitting resistance (PI ≥ 40) and Better resistance to stress corrosion, Ni-based alloy and titanium alloy alternative materials. Followed by high temperature or corrosion resistance of the performance, with more excellent high temperature or corrosion resistance, 304 stainless steel can not be replaced. In addition, from the classification of stainless steel, special stainless steel microstructure is a stable austenitic microstructure.

Will stainless steel rust? 
The answer is yes, so rusty stainless steel how to deal with it?
      First of all from the reasons for rusty stainless steel. When the stainless steel surface of the passive film corrosion resistance in the weak part of the formation of pitting due to self-induced reaction, and then the formation of small holes, slowly with chloride ions close to the final formation of a highly corrosive liquid, More speed up the corrosion rate of stainless steel. There is also a reason for the corrosion of cracks between the crystal within the stainless steel, which destroyed the stainless steel surface of the passivation film. Therefore, the surface of stainless steel must always be cleaned and maintained, so as to extend its service life. However, when cleaning the surface of stainless steel should pay attention to: stainless steel surface can not scratch the phenomenon; can not use with bleach ingredients and abrasive cleaning solution, if the use of washing liquid, must be used after the end of clean water rinse.
1.When the stainless steel surface is grease, oil pollution, you can use a soft cloth to wipe clean, and then use a neutral detergent or ammonia solution cleaning.
2.When the stainless steel surface appears rainbow pattern, because too much use of detergent or oil caused by washing with warm water neutral detergent can be cleaned.
3.When the stainless steel surface is dusty or easy to go out of the dirt, you can use soap, weak detergent or ask to rinse. Trademarks on the surface of stainless steel, when washed with warm water or weak detergents, the adhesive ingredients should be rinsed with alcohol or organic solvents.
4.When the stainless steel surface rust occurs, you can use 10% nitric acid or grinding detergent cleaning, you can also use a special detergent cleaning. Therefore, if you want to keep the bright stainless steel, clean the surface, while extending its life, the above must be done!
