BS EN 10217-7 2014 is the latest revision for stainless steels for welded tubes for pressure purposes. The standard was first published in 2005. The latest revision has not added any new grades. Some anomalies have been corrected. Nickel and chromium contentes are now quoted to 1dp compared to 2dp. The nickel content for grade 1.4307 is now harmonised at 8.0/10.5 in line with other standards. It had been 8.00/10.00 in the 2005 version.

 

Included in the standard are chemical compositions, delivery conditions and process route symbols, ambient temperature mechanical properties, some additional optional tests (leak testing, flattening, drift expansion, bend and non-destructive testing) and some dimensional and tolerance requirements.
Austenitic (19), and austenitic-ferritic (duplex) (4) stainless steel grades are included in the range of grades specified in this standard. Only the chemical composition of the stainless steels in the standard are listed in this article.

 

It is interesting to compare the grades listed in this standard with those in the standard for welded stainless steel for general engineering purposes BS EN 10296-2. See table below. The implication of this is that some grades can be used for pressure purposes which cannot be used for general purposes. It is unlikely that this anomaly was the intention of the standards writers.

 

It might be expected that any steels appearing in BS EN 10028-7 Flat products for pressure purposes would appear in the comparable welded tube standard. This is not the case. The following grades in BS EN 10028-7 are not found in BS EN 10217-7:

 

Ferritic grades - 1.4003, 1.4516, 1.4510, 1.4521, 1.4520, 1.4509

 

Martensitic grades - 1.4313, 1.4418

 

Austenitic grades - 1.4318, 1.4315, 1.4406, 1.4335, 1.4466, 1.4580, 1.4434, 1.4537

 

Duplex grades - 1.4507

 

Creep resisting steels - 1.4948, 1.4950, 1.4951, 1.4941, 1.4958, 1.4959, 1.4910, 1.4961
