ISO 13520 is an international standard on austenitic stainless steel castings that discusses the best procedures and specifications required for determining the ferrite content in austenitic stainless steel castings. ISO 13520 specifies methods and procedures for estimating ferrite content in austenitic stainless steel castings by chemical, magnetic, and metallographic means.
ISO 13520 on ferrite content in austenitic stainless steel castings is relevant to:
Austenitic stainless steel castings are non-magnetic. When nickel is added to stainless steel in sufficient amounts the crystal structure changes to “austenite”. The basic composition of austenitic stainless steel casting grade is 18% chromium and 8% nickel.
ISO 13520 provide guidance on the methods and procedures of determining ferrite contain in austenitic stainless steel castings
As a user of ISO 13520, you can efficiently determine the ferrite content in austenitic stainless steel castings. ISO 13520 helps you in manufacturing high-quality austenitic stainless steel castings. ISO 13520 provides you with comprehensive information useful throughout the process of ferrite determination.
