Determination of ferrite content in austenitic stainless steel castings ISO 13520:2002

Publication date:   Oct 3, 2002

Scope

In ISO 13520 procedures are covered for estimating ferrite content in certain grades of austenitic iron-chromium-nickel alloy castings that have compositions balanced to create the formation of ferrite as a second phase in amounts controlled within specified limits. Methods are described for estimating ferrite content by chemical, magnetic and metallographic means.
