Cladding of Stainless steel

[deepsok]

I need to understand the pro's and con's of cladd steel.
Is the cladding can be used as effecient as other SS with respect formability.

Are you talking roll bonded, explosive bonded, or weld overlay?
You can form SS over CS well. But you don't want to re-heat treat afterward. you may seriously sensitize your SS and end up with little corrosion resistance.
This might require the selection of a different CS alloy than you would normally use.

Hi Deepsok,

I noted this posting dates back a few months. However the attached booklet will explain a lot of things about Roll Bonded Clad Plates.

Feel free to take a look and revert back with any queries, if you have. As a welding engineer in the past I had handled numerous cladded vessels and exchangers, involving, 304/316/321/347 S.S , Duplex S.S, Incoloy 625/825 and Monel 400 and Nickel-200 alloys, with various substrates,e.g C.S and LAS.

Thanks

You question is a bit vague, as it what do you mean by efficient. As a general rule if the thickness of your plate is greater than 1/2" (13mm) you should evaluate the cost of using clad plate vs. solid stainless plate. Clad plate is almost always more cost efficient than solid when the thickness is 3/4" (17mm). There are not problems with forming properly produced clad plate.

Go to DMC website for great information on explosion bonded plate

If you want more specific information you need more specific questions.

Stainless clad carbon or low alloy steels have primarily two advantages over full thickness stailess steel:
1. Much lower cost
2. Resistance to stress corrosion cracking.

It's [roll and explosion bonded forms] primary disadvantage is the long lead time to obtain due to its few suppliers.

Hope this helps too.
