HI Friends,

I am working in choke valve industry.
Mostly , tungsten carbide has been used for choke valve trim.

Is there any international standard for tungsten carbide's different grades in which i can found chemical as well as mechanical properties.

First define what you mean by tungsten carbide.

Hi Edstainless,

Great Thx.
it is good information for me.
just one question that all those grade has been followed by any international standard?
Like ASTM or other....?

RE: Tungsten carbide Grade

No, last that I knew the ASTM spec covered the various things that get measured (composition, grain size, magentics, and so on) but they don't cover the actual carbide variations.
