Cast Iron Cooking Grates

what are the benefits? in other words, why would i want one of these instead of the standard stainless steel grates?

There are none.

+1 except the cast iron won't warp on hot burns...but then the SS won't break either....nolaegghead said:There are none.

Some folks love the grill marks CI grids leave on meat. Here is a good analysis, and some information why grill marks may not produce the best tasting meats. http://www.amazingribs.com/tips_and_technique/mythbusting_grill_marks_and_flipping_meat.html
Instead of a CI grid, I use a CI griddle to get the maillard reaction over a wider area.

CI has better heat transfer, heat retention and has more even heat distribution and once seasoned food tends to stick less. Obviously opinions differ. I prefer CI grid and CI pan, skillet etc.LBGE 2013 & MM 2014Die Hard HUSKER & BRONCO FANFlying Low & Slow in "Da Burg" FL

Science party pooper guy here.
No offense @NPHuskerFL, but you can't have better heat retention and transfer at the same time. CI retains heat better, transfers slower - conducts heat slower. Non-stick is more a function of how smooth and seasoned the material is. Generally the cast iron stuff has more mass than the steel or stainless so you can get alot more heat in it. Keep in mind, CI, steel and stainless are all iron alloys and they the same amount of heat per weight. The crystalline structure makes them transfer it differently.For practically still fluids - average values for the overall heat transmission coefficient through different combinations of fluids on both sides of the wall and type of wall - can be found in the table below:
Fluid Transmission Surface Fluid Overall Heat Transmission Coefficient (Btu/ft2 hr oF) (W/m2 K) Water Cast Iron Air or Gas 1.4 7.9 Water Mild Steel Air or Gas 2.0 11.3 Water Copper Air or Gas 2.3 13.1 Water Cast Iron Water 40 - 50 230 - 280 Water Mild Steel Water 60 - 70 340 - 400 Water Copper Water 60 - 80 340 - 455 Air Cast Iron Air 1.0 5.7 Air Mild Steel Air 1.4 7.9 Steam Cast Iron Air 2.0 11.3 Steam Mild Steel Air 2.5 14.2 Steam Copper Air 3.0 17 Steam Cast Iron Water 160 910 Steam Mild Steel Water 185 1050 Steam Copper Water 205 1160 Steam Stainless Steel Water 120 680 - 1 Btu/ft2 hr oF = 5.678 W/m2 K = 4.882 kcal/h m2 oC - Unit Converter

So what that table tells us is copper transfers heat the best (out of the list) and CI the poorest. That's why they put copper in pans - to keep the heat even by spreading it out, and why copper is used for heat exchangers and radiators. If aluminum were in that list, it would be higher than all steel alloys.______________________________________________I love lamp..

There's nothing wrong with cast iron other than it breaks like ceramic.______________________________________________I love lamp..

Not meaning to buck the trend here, but I believe cast iron provides a better sear and better flavor on a steak and on burgers...but that is just me and my taste buds and perception no science involved!

@nolaegghead Well thank you Mr Science Guy ;-). Oops. Yep. SS has better heat transfer (it sheds heat almost as quick as it gains it). And CI ability to retain heat, in my book, is a positive.

Perception is a wonderful thing. Take the same food, split in two, make one pretty the other ugly, the pretty will "taste" better every time to anyone who isn't blind. So there's something to be said for it, as perception is reality. Also global climate change is a giant conspiracy by 97% of the world's scientists.Bayarad said:Not meaning to buck the trend here, but I believe cast iron provides a better sear and better flavor on a steak and on burgers...but that is just me and my taste buds and perception no science involved!

Stainless steel can make sear marks just as well as CI. I sort of proved that with a bit of over the top searing, lol:

There is one small plus to the cast iron grid. The cooking bars are very close together. This is a plus when cooking very small items such as unskewered shrimp and clams. As with most things in the cooking world the cast iron vs ss is open to much subject and debate. That being said I like and use both for different things. I really like the wide flat side of the cast iron for cooking fish fillets and small vegetables. It works wonderfully for this purpose. My recommendation is to purchase and use one of each for different cooks. Just a friendly reminder. The above is just my opinion and what works very well for me. Others mileage may vary and differ. They are both excellent for intended purposes.

@SGH and @nolaegghead. What I love about this forum is the wonderful information but a bit of banter and "raillery" is always enjoyable too.

@SGH - I agree with you but I'd like to point out the advantages and disadvantages are more a product of the physical shapes we typically see that are different in a cast versus a welded product and not in material science. Mickey has a water-jet cut steel grate, so is the swing grate I believe - made of steel, not cast, yet have narrow openings and mass like cast grates. These both act like what you're saying cast iron does because of the physical characteristics.______________________________________________I love lamp..

@nolaegghead
I certainly agree with you brother. Not trying to build a case for either. I use and enjoy both. I believe everyone should have and use each. I like them both for different reasons.Location- Just "this side" of Biloxi, Ms.

@nolaegghead
I find that they cook equal. No difference in food quality. I just like the small gap and flat side of the cast iron for certain cooks. Seems to make it easier to me. Examples- Fish, shrimp and small vegetables.Location- Just "this side" of Biloxi, Ms.

@SGH - I think we agree. I originally said there was no advantage, the question was one of materials. If it was about mass or shape I would definitely mention there are advantages there.______________________________________________I love lamp..
