Stainless steel plate generally chromium content in the steel is not easy to rust. Nickel chromium content is higher, the better the corrosion of the stainless steel in general will not rust, smelting technology of manufacturing enterprises may also uns s32760 plate affect the corrosion resistance of stainless steel, smelting technology, advanced equipment, advanced technology of large stainless steel factory whether the control of the alloying elements, impurity removal, the billet cooling temperature control can be guaranteed, so stable and reliable product quality, internal quality is good, not easy to rust. Conversely some small steel mills poor equipment, process behind, smelting process, impurities, does not remove products will rust.
Stainless steel plate and the air humidity is big, continuous wet weather, or areas including ph value in the air environment is easy to rust. 304 stainless steel material, also will rust if poor surroundings, cream or spray assisted with pickling corrosion parts form a chrome oxide film to passivation to restore it to corrosion resistant ability, pickling, in order to remove contaminants and acid residue, proper wash with water is very important. After all processing to polished with polishing equipment, polishing wax can be closed. Can also be used to local slight pitting 1:1 gasoline and oil mixture with a clean cloth to wipe the rusty spot.
Stainless steel plate, sand blasting, glass or uns s31803 sheet ceramic particles shot blast cleaning, annihilation, scrub and polishing. Using mechanical method could wipe cleared before material, polishing materials, or annihilation caused by pollution. All pollution especially foreign iron particles might be the source of the corrosion, especially in the moist environment. Therefore, the mechanical cleaning surface shall conduct regular cleaning under dry conditions. Using mechanical method can only clean up its surface, can't change the corrosion resistance of the material itself. So after the mechanical cleaning used to polishing polishing equipment, polishing wax seal.
Stainless steel plate is brown rusty spot point how to deal with, when 347 stainless steel the stainless steel plate is brown rusty spot (point), the big surprised: people think that "stainless steel is not rusty, rust is not stainless steel plate, steel presents a might be the problem". Actually, this is a lack of understanding of stainless steel plate of a unilateral mistake. Stainless steel plate under the condition of must also will rust.
Stainless steel plate with atmospheric oxidation resistance ability - namely, stainless, also with the acid, alkali, salt corrosion medium is talent - corrosion resistance. But its corrosion resistant ability of intrusive is with the chemical composition of steel itself, mutual condition, using conditions and environmental medium type and change.
