Material Translation

03/25/2011 4:48 PM

I'm working on a quote to fabricate replacement parts for a hydroelectric turbine and I need help on a couple of the materials. I'm not sure what these two materials convert to: GSnPb Bz717 and GBz14. Please help if you can.

Thank you,

Gene

Without any real idea what you are doing that's all I can find.

Looks like a material spec and a seismic spec.

Thank you, lyn.

I'm going om a site visit wednesday and will try to locate an original BoM. The Hydroelectric plant owners, to whom my rebuild quote will be submitted, are getting no response from the original manufacturer. I wish not to use substitute material(s).

I used to have access (many years ago) to a publication called "Stahlschlussel" (literally 'key to steel') which cross-referenced materials from special cast-irons to high-grade chrome/nickel alloys between English, American, French, German, Japanese and other designations. I have not been able to find it online, except to buy, but it would certainly tell you what you need to know. I suspect GBz14 could be an Aluminium Bronze, but I don't recognize the other. Can you not get the material specs from the turbine manufacturer? Or is it all in Russian?

Hi Holzfeller.

I have an older version of Stahlschlussel, as well as Worldwide guide to equivalent irons and steels and Worldwide guide to equivalent nonferrous metals and alloys and a couple other great references, plus my own info.

But as lyn has just shown us, sometimes just working online can get you what you need.

Have a great day all.

Milo
