Weldable heat resisting steel forgings and rolled or forged steel bars Technical delivery conditions
 N 17243

Annotation

Field of application

This standard applies to weldable heat resisting steels as listed in table 1 where these can be supplied as forgings, or rolled or forged steel bars.

Note. In agreement with EURONORM 79, the concept "forgings" includes hot pressed parts (such as collectors or container courses with pressed-on bottoms) and parts produced on ring rolling mills (such as seamless rolled rings).

Products covered in this standard are mainly used for steam boiler plant, pipework, pressure vessels and similar components. If these products are used for plant subject to regular inspection, the relevant codes of practice (such as TRD, TRG and TRB) shall also be observed. This also applies to applications covered in other codes of practice.

This standard also applies to forged or rolled semi-finished products intended for processing into finished products as specified in subclause 1.1, the condition on supply and the relevant methods of test being, however, the subject of a particular agreement when ordering such products.

DIN 17155, DIN 17175, DIN 17177 and DIN 17240 also cover heat resisting steel products.
