Non-destructive testing of steel forgings - Part 4: Ultrasonic testing of austenitic and austenitic-ferritic stainless steel forgings
N EN 10228-4
Annotation
This European Standard describes techniques for the manual, pulse-echo, ultrasonic testing of forgings manufactured from austenitic and austenitic-ferritic stainless steels. Mechanized scanning techniques, such as immersion testing, may be used but should be agreed between the purchaser and supplier (see Clause 4).
This part of EN 10228 applies to four types of forgings, classified according to their shape and method of production.
Types 1, 2 and 3 are essentially simple shapes. Type 4 covers complex shapes.
This part of EN 10228 does not apply to:
— closed die forgings;
— turbine rotor and generator forgings.
Ultrasonic testing of ferritic and martensitic steel forgings is the subject of Part 3 of this European Standard.

Испытание без разрушения стального создания - Часть 4: Ультразвуковая дефектоскопия аустенитного и аустенитно-ферритового создания нержавеющей стали
Этот европейский стандарт описывает методы для руководства, импульсного эха, ультразвукового испытания штамповок, произведенных от аустенитной и аустенитно-ферритовой нержавеющей стали. Механизированные методы сканирования, такие как испытание погружением, могут использоваться, но должны быть согласованы между покупателем и поставщиком (см. Пункт 4).
