The performance of stainless steel sheets

Uniform corrosion refers to the metal surface contact corrosion medium total corrosion phenomena. According to different demands of different indicators on corrosion, can generally be stainless steel sheet  into two categories: Stainless steel sheets refers to the corrosion in atmospheric and weak corrosive medium steel. The corrosion rate less than 0.01mm/ year, considered to be "completely corrosion; corrosion rate less than 0.1mm/ year", that is "resistance". Corrosion resistant steel tube which can corrosion in various strong corrosive medium steel. Point corrosion refers to the metal material surface most no corrosion or slight corrosion and local corrosion occurred in highly dispersed, common corrosion spot size of less than stainless steel sheet coil , depth is often greater than the surface of the aperture, the light has a shallow pit, serious and even the formation of perforation. Crevice corrosion is a macro etch pits mottled or ulcer formation occurred in the metal component in the gap, which is a kind of local corrosion. Stainless steel sheets intergranular corrosion is a selective corrosion, with the general difference is that selective corrosion, localized corrosion is a microscopic scale, and the macro is not necessarily local.

stainless steel 304 sheet industrial pipes

Water contamination in its storage and transportation problems has been growing attention. Practice has proved that a large , qiyi 304 stainless steel coil water preparation, storage, transportation , purification , recycling, desalination and other water industry 's best selection . Its advantages are: corrosion resistance, earthquake , water , sanitation ( no rust and patina ) , light weight ( to reduce 1 / 3 ) , less maintenance , long life ( can use 40 years), life cycle cost (LCC) Low , is a recyclable green materials . According to reports, Tokyo, Japan region reached 76% of stainless steel pipes , pipe leakage rate from the current 14.7 % to 7.5 %. After Osaka, Japan suffered a major earthquake , stainless steel water tanks intact. Recently, the stainless steel sheet coil bellows joints, so that the construction cost of the stainless steel water pipeline reduced by 20% , 3% of the total costs , maintenance costs are reduced by 3 /4.
