Although stainless steel is widely known for resisting corrosion, it isnt completely impervious to corrosion. Under the right (or is that wrong) circumstances, stainless steel alloys can become corroded. Many a manufacturer has ordered a stainless steel part or basket, only to find that their stainless steel has started to show signs of rust and/or other problems within a few days or CORROSION RESISTANCE OF THE AUSTENITIC cance. Zf, for example, a test indicates a corrosion rate of .OOl mils penetration per year for Steel A, and .002 for Steel B, it should not be concluded that Steel A is twice as good as Steel B, but rather that both steels are entirely suitable for service in the environment. * 1:* I
Corrosion Resistance Chart. To use the calculator, please view this page on a desktop computer or on "Desktop Mode" if using a mobile device. The figures quoted in the table below based on BS 6501 2004 standard and present the following categories of resistance to corrosion: Corrosion Resistance of Stainless Steels - IMOACorrosion resistance of stainless steels Corrosion in concrete (corrosion problems are not limited to outside surfaces !) Stainless steel provides both strength and corrosion resistance inside the concrete, providing a long, maintenance-free service life of the structure. Corrosion of unprotected carbon steel occurs even inside reinforced Corrosion resistance levels in stainless steel - RyersonThe emphasis on corrosion resistance is important due in large part to the varying types of environments in which the end products are used. Lets start with a basic rule of thumb, which says the higher the chromium levels contained within the stainless steel, the more corrosion

Metals close to one another on the chart generally do not have a strong effect on one another, but the farther apart any two metals are separated, the stronger the corroding effect on the one higher in the list. Galvanic Corrosion Chart - Zip FastenerThis is a handy chart to compare galvanic corrosion potential with common materials. Zinc is on top of the list, which is commonly used as a sacrificial layer for corrosion on fasteners. To be used only as a guideline to compare materials for galvanic corrosion Zinc Galvanized Steel Aluminum Cadmium Cast Iron Lead Mild Steel Tin Lead-Tin Solder
Housings and frames can be furnished in all stainless steel, aluminum or Monel. The exact grade of metal used depends on the nature of the installation. Unless otherwise specified, #304 housings will be furnished when stainless steel is ordered. #316 stainless steel is also available.

Austenitics are the most specified stainless steel grades thanks to their excellent formability and corrosion resistance. Austenitic stainless steels contain 15%-30% chromium and 2%-20% nickel for better surface quality, corrosion and wear resistance, and workability.

This corrosion occurs when a crevice between the stainless steel and another material allows chlorides to concentrate or prevents proper oxygen levels to regenerate the steels oxide layer. While typically found near or within the gap between two metals, crevice corrosion can also occur between metallic and non-metallic surfaces.Corrosion resistance table - Dacapo StainlessStainless steels can be susceptible to certain localised corrosion mechanisms, namely crevice corrosion, pitting, intercrystalline corrosion, stress corrosion cracking and bimetallic (galvanic) corrosion. Localised corrosion is often associated with chloride ions in aqueous environments. Corrosion resistance relies on a good supply of oxygen.
