Material Selection for Blank Flange

Material Selection for Blank Flange

Material Selection for Blank Flange

(OP)
Hi Everyone,
I am having to carry out some pressure proof tests on some ceramic sleeves. The sleeves will be clamped between a pair of flanges.
I have designed the flanges and now need to select a material. It needs to have a yield strength of 355MPa and be readily machinable - it has to have o-ring grooves machined in it. It is only going to be used once or twice so does not need any special surface protection.
I have a number of sizes to produce ranging up to 180mm diameter. The maximum pressure (cold water) will be 400bar.
What material should I select?

RE: Material Selection for Blank Flange

BriComp, I don't know why you specify a yield strength, but that to some extent answers you own question, as I believe you will find that carbon and low alloy steels are out, austenitic stainlesses are out, all common metals are out. You may be looking at duplex SS or nickel alloys.

If you are only going to use it a couple of times why not go common, cheap and thick?

Mike
