weldability of 17-4 ph stainless steel

Date 12-03-2009 14:46

There is actually quite a bit of info all over the internet on this material. Its a common PH.
ASM Handbook volume 6 has some good info as well.

hello friend
may be you're right that this steel is common ph, but actually i can't find any paper about weldability of 17-4 or dissimilar welding with another alloy. i want academic paper with experimental result? do you know such document?
title of my MSc thesis is laser or tig welding of 17-4 presumably. for this reason, i looking for prior research about this subject.

Here's some interesting "stuff' on a variety of stainless steels including some thesis papers as well from The University of Cambridge in England:

This should keep you busy for a while... You need to learn how to surf the internet better my friend!!! :) :) :)

Here's a brief article on the reason for PH stainless steels and PH in general... this brief focuses mostly on 17-7 and A286, but it may be helpful towards your thesis to some slight degree. :)

Henry,

There is a gentleman in the "technical" forum looking for help on some P91.
Maybe you can offer him your expertise?

Really? I thought that you would take care of that sort of light work for me!!! :) :) :) I'm confident that you can handle his query, or am I overly confident in your ability?

Respectfully,

Considering only js55 and myself is the only ones who has replied, I thought some expert help was needed!

Do not hijack this thread! The person works for SEPCO and he should be able to have access to all of the applicable code reference necessary to answer his own query, so just tell him to ask around his office! they have plenty of experience in P-91 piping, so go find someone else to play with! ;)
