Material Comparisons between ASTM and EN

Material Comparisons between ASTM and EN

Material Comparisons between ASTM and EN

(OP)
I know that this question will have been asked in a number of different ways over the years but I'm going to ask it again.

For those of you that don't know there is a new European Directive that became legally binding from may this year (2002). Compliance with the directive is automatic when materials are covered by a EuroNorm.

This poses a problem in the UK as we have never related our materials to werkstoff. For pressure vessels we have tended to use ASTM materials, being applicable to both PD5500 (previously BS5500) and ASME design codes.

This has been of great benefit to our inventory control. The PED (pressure equipment directive 97/23/EC) has now thrown this out of the window. Although you can still use ASTM materials, when they are used for flanges, etc. the allowable pressure ratings are lowered in comparison to the EuroNorm materials.

What would be really handy is if there was a list of materials that could have mutiple certification. For example ASTM A182 F316 can also be certified EN 10222-5 1.4404. This association is easy for stainless, not for carbon.

Is there a site that can do this? (I've already tried MatWeb.)

If there isn't, does anybody out there have the inclination to create one?

Any help would be gratfeully received.

Regards,

fawkes
