Effects of Mn, P, S, Si & V on the Mechanical Properties

As such its content in most steel is limited to a maximum of 0.05%. Phosphorus prevents the sticking of light-gage sheets when it is used as an alloy in steel. It strengthens low carbon steel to a degree, increases resistance to corrosion and improves machinability in free-cutting steels.

FAQ 1 Galvanic/Dissimilar Metal Corrosion

The stainless steels, including 304 and 316, are more positive than zinc and steel, so when stainless steel is in contact with galvanised steel and is wet, the zinc will corrode first, followed by the steel, while the stainless steel will be protected by this galvanic activity and will not corrode.

Brass to Iron Pipe Corrosion Prevention Sciencing

Apr 24, 2017 · The Galvanic Series is a list of 12 different metals that share electrons between one another for corrosive action. Iron is ranked number 4, whereas brass is a higher number 9 rank. As a result, the higher ranked metal will corrode the lower ranked metal. The iron will release electrons to the brass, generating corrosion along the iron piping.
