Can we weld 316L material with 316H filler.

Yes, but what is the application?

When carbon is added to steel it results in higher strength, higher hardness, at the expense of ductility. In the case of type 316 austenitic stainless steel, it provides the designer with a higher allowable unit stress at higher temperatures than type 316 without the higher carbon content. However, more carbon translates into greater problems of the formation of M23C6 (carbides) when the stainless is welded or if the service temperature is up around 1000 degrees. Most people refer to the problem as sensitization. The problem manifests itself as intergranular stress corrosion and intergranular stress corrosion cracking when an electrolyte containing a halide such as chloride is involved.

Al is correct
(damn agreed with an inspector:roll::eek::yell::surprised::mad:)
my thoughts are always use same filler compound as base material
makes metallurgical sense
there are other things to think about
but need more info
give more info learn more
we all will

Kent, does that apply to 304?

Inspector? I always considered myself as a welder that can inspect. After all, I retired from the Ironworkers with 45 years of service.

Al :evil:

get that off google, aka code book or a Kent off the top of your head?:twisted::evil::razz:
btw your one of the few I have real honest respect for your knowledge:cool::grin:

I thought that would get your attention. After all, you said one should always match the base metal. Generally I would agree with you, but 304 is the exception.

Also austenitic 321 stainless is typically joined with 347

Just an example to add to the conversation

We just hijacked this thread
Lar you are correct
(now I agreed with a CWI and CWE:confused::eek::red::razz::wink:)
but Lar, you do make the list of people who's knowledge I respect:cool::yell::smile:
(now if you can get Mr. Al Moore to buy dinner you can make the top of the list:twisted::wink::evil:)
btw you made the list by knowing Walt (he does impress me)

Thread hijacking..... Check!

I think the OP needs to deliver data if he wants more.

As for Al...   He lost a lobster dinner wager to me once upon a time, and he paid in Full!   

It took a couple years but it was worth the wait.

they all think they have all the answers
have some fun
joking and kidding around is what friends do :twisted::evil::cool::yell::smile::razz::grin:
then again no one on there are personal friends
just my thoughts
