Design Guidelines for Stainless Steel in Piping SystemsCommonly used stainless steel material is having corrosion problems like pitting, SCC, erosion, galvanic corrosion etc. Brief description of all these corrosion problems associated with stainless steel is tabulated in this blog. The corrosion experienced in 300 series stainless steel is described in a variety of technical terms. 21 Types of Pipe Corrosion Failure

Corrosion is when a material breaks down because of its environment. In general, stainless steel is much more resistant to corrosion than carbon or alloy steels. Stainless steel is an iron alloy and is made up of 10.5% chromium as a minimum. This chromium causes a very thin layer of oxide to build up on the surface of the metal which is often Corrosion of Piping Carbon Steel Stainless Steel Cast

Corrosion of Piping Carbon Steel Stain

Galvanic corrosion is the rea connecting carbon and stainless steel can lead to problems. Galvanic corrosion is when one metal causes another metal to corrode and break down. For this corrosion to start, there need to be three things an anode (one metal), a cathode (a second metal), and an electrolyte (water is a common one).
