ASTM E 426 - 98. Standard Practice for Electromagnetic (Eddy-Current) Examination of Seamless and Welded Tubular Products, Austenitic Stainless Steel and Similar Alloys

American Society for Testing and Materials (ASTM). 1998, 4 pages.
This practice2 covers procedures that may be followed for eddy-current examination of seamless and welded tubular products made of stainless steel and similar alloys such as nickel alloys. Austenitic chromium-nickel stainless steels, which are generally considered to be nonmagnetic, are specifically covered as distinguished from the martensitic and ferritic straight chromium stainless steels which are magnetic.
