Stainless Steel Corrosion Rate Table

In order to calculate the rate of corrosion the following information must be collected.

Stainless steel corrosion rate table.

400 series stainless steel. Corrosion of unprotected carbon steel occurs even inside reinforced. Good heat resistance weak corrosion resistance 11 cr 8 ni. Corrosion 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.

The cheapest model uk us commonly used as a car exhaust pipe is ferritic stainless steel chrome steel. This is collated information from various sources but is of limited quality. Are normally calculated using mils per year. Corrosion rates in the u s.

Corrosion of carbon steel occurs when the relative humidity of the air is 70 to 80 and the air temperature is above 32 f. Belongs to ferrite stainless steel and martensitic stainless steel. Corrosion rate 0 1 1 0 mm year. Corrosion rate less than 0 1 mm year.

Corrosion rates may be accelerated by air impurities that dissolve in condensed water or rain water and by dust and dirt settling on the metal surface. The material is corrosion proof. The table below indicates the approximate corrosion resistance of selected corrosion resistant metals to a range of common chemicals. Corrosion resistance 1 good 2 be careful 3 not usable fluid.

Carbon steel 7 8 titanium 4 5 corrosion criteria. For full table with durimet monel hasteloy titanium cobalt base alloy and 416 stainless steel rotate the screen. Corrosion resistance table stainless steels can be susceptible to certain localised corrosion mechanisms. The chemical compatibility of a range of stainless steel types with a large range of acids bases compounds some foodstuffs and liquid metals can be assessed using these tables.

In other words the corrosion rate is based on the number of millimeters thousandths of an inch penetrated each year. This article provides a link to the outokumpu web site this provides a web based version of the tables published as the outokumpu stainless corrosion handbook. In industrial environments the choice to which stainless steel to sue is fairly broad except many users tend to prefer the 300 series stainless steels such as type 304 because of their all around good corrosion performance and ease of fabrication.
