321 321H Stainless Steel Description
321 stainless steel is Ni-Cr-Ti austenitic stainless steel, its performance and 304 is very similar, but due to the addition of metal titanium, it has a better resistance to grain boundary corrosion and high temperature strength.
321 stainless steel where Ti exists as a stabilizing element, but it is also a hot steel at the same time, much higher than the 316L in high temperature .321 stainless steel in different concentrations, different temperatures of organic and inorganic acids, especially in the oxidation The media has good wear resistance, used in the manufacture of wear-resistant acid containers and wear-resistant equipment lining, pipeline.
321 stainless steel is Ni-Cr-Ti austenitic stainless steel, its performance and 304 is very similar, but due to the addition of metal titanium, it has a better resistance to grain boundary corrosion and high temperature strength. Due to the addition of metal titanium, so that the effective control of the formation of chromium carbide.
321 stainless steel has excellent high temperature stress breaking (Stress Rupture) performance and high temperature creep resistance (Creep Resistance) stress mechanical properties are better than 304 stainless steel.
347H austenitic stainless steel, with good corrosion resistance, welding performance and thermal strength. 347H stainless steel for large boiler superheater, reheater, steam pipe, petrochemical heat exchanger pipe fittings.

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!
