    Most of the stainless I've worked (300 or 400 series) with will permanently discolor around 600F, turning kind of a gold/bronze color. At higher temperatures it will turn blue. Warping and weld failure probably depends on part geometry and weld quality - we regularly use stainless steel for high pressure containment vessels up to 1200F.


    You can spend a lot of time and money picking out the perfect floral bouquet for your date ... but you're probably better off checking if you have bad breath and taking the porn out of the glove compartment.

    The moral: you gain more by not being stupid, than you do by being smart. Smart gets neutralized by other smart people. Stupid does not.

    I would think it depends on the alloy. I think it's higher the mild steel and cast iron due to the rare earths. Need one of our MatE friends to speak up!

    I believe the ASM reference books on materials has this information. It used to be available online through the ISU library under reference section (if you're still a student you should have access). They pay good money for this, so you should definately take advantage.

    I graduated in in 2003, so no I don't have access.

    Re: Question for chemists or metal workers

    What grade of stainless? What thickness? The nickel content, finish (brushed vs annealed), and thickness will all play into your question.


    It is the mark of an educated mind to be able to entertain a thought without accepting it.

    Remember, you're unique. Just like everyone else.
