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.
