Cast iron grate

i just went out to throw some cauliflower on the grate and discovered it was cracked... in 3 places !  Figured iron was pretty much indestructible !

    Actually cast iron is rather soft and when the BGE style cast iron grate is first heated then the center gets hot and expands while the outer circle remains much cooler. The expansion causes the stress cracks.

    It is a BGE grate.  Thanks for the explanation Ron.

    While I found mine fun to have initially, I also found it to have the said issues, and high maintenance.   Mine is gone and I don’t miss it at all.

    Cast iron is a very brittle metal. Not one of my better purchases.  I'll stick to stainless.

    Cast iron does not like fast heating or cooling.  My material science class is years behind but it lacks the carbon that gives steel its durability and ductility.  I think I’m going to have a steel grate water jetted for my bge out of 1/4” or 3/8” at some point from regular mild steel and see how that works over cast.

    I've had my CI grate for 6-7 years.  There is one crack on the outside edge, but I use it for all my cooks, both high and low temp.

    Been using mine for several years and also has a small crack on outer edge, does not interfere with the performance.

    I use it for all my direct cooks on the Large, will be getting one for the Mini Max soon.

    My Fire Grate, that is another story, they do not last very long for me.

    I have been using CI on my small and large for the past 8 years, use them for every cook, direct, indirect, low and slow, pizza, etc.  Happy so far....
