what alloys are suitable as replacement for A36?
« on: June 28, 2023, 08:55:41 AM »
hi,

im having trouble to find A36 steel sheets around here, but was managed to find A106 and A355.

all 3 symbols mean jack to me, but with your help i might be able to choose.

The main thing is to not get stainless as it has the wrong thermal properties.

A106 seems to be mostly about pipe but if there's sheet of it that should work fine. A355 seems to be a tool steel with some chrome and aluminum to make it easier to nitride coat it. Sounds expensive, and i wouldn't personally choose something with chromium in it

My local metals vendor has a selection of off-cut remnants in their parking lot and i just bought a piece that would fit on the rack in my oven. I'd have to have someone shoot it with an xrf gun to find out what alloy it is.

A36 is one of the most common types of steel there is. Any metal shop worth their salt should have plenty.

and here we are... it's not available under this name.... so hard work to get it.


is there an element (atom) i should avoid for buying an alternative alloy?

The basics are mostly that stainless steel is too expensive and doesn't have the thermal properties you want anyway, and that alloys that have chromium in them are probably not the best idea because of the toxicity of chromium, even though it probably won't put any in the food, and these alloys are also expensive. It's unlikely that someone who deals in metals professionally will accidentally sell you a chromium alloy. They know they can get a premium for it from people who need it for reasons.

It wouldn't be unreasonable to just explain to the vendor what a pizza steel is and ask for the cheapest piece with the dimensions you want. At least 3/16", not more than 1/2". It will probably be A36, and if you're lucky they are willing to make you a deal on an off-cut remnant. My 14x14x.5 slab was $40 including sales tax.

I have a hard time believing that most people in civilization are more than an hour from an outfit that sells steel sheet, angle, etc. You'd have to be somewhere pretty remote. For me the primary vendor is MetalMart, about 15 minutes away. But they are hardly the only one.

If we knew your location beyond "here" as it says in your profile :-D, it would be helpful. I'm assuming you're not in the US since you can't find A36, so maybe a more specific location would be helpful. We have members from all over the world, perhaps theres someone near you on the forum that can tell you where to go and what to ask for.

I believe you'll also be fine with 1018 or 1045. I thought there was also 1015 and maybe 1010 but I didn't see them just now. 1000 is carbon steel and the last 2 digits are carbon content if I remember correctly.

A106 is carbon steel pipe.  A355 is alloy steel bar.  A36 is a mild carbon steel plate or shape (e.g. angle iron).  Alloy will cost you much more.

Where are you?  In the US, A36 is available everywhere.  It is one of the most common plate specs.  What kind of places are you checking for this material?  Anyone that says they can provide you A106 plate doesn't know what they're talking about.

thanks

i'm from israel, and the astm method is apperantly not common here in pizza steel materials.
the closest s235 steel so i ordered it... hopefully it will fit for the job.

S235J2 is an EU structural steel equivalent to A36.  It should be fine.

Do you carry this aversion to chromium alloys into the kitchen? Do you not have any stainless steel saucepans or fry pans? I personally opt for those because I don't like any copper or aluminium cookwate around my food.

You have a point. There's *some chromium in stainless and I'm generally not concerned about it. I vaguely recall having read that one of the steel grades they mentioned was a high-chromium tool steel.

I actually don't really have qualms about aluminum cookware either, though it's certainly more usable if it is hard anodized or teflon coated. I have a fair bit of bare aluminum bakeware that i like just fine.

316 and 304, perhaps the two most common types run 16 to 20% chromium, but its never worried me, though thinking on it, maybe it would if I were using it in a wood fired situation.
Aluminium has bothered me for years since I read it was linked to Alzheimer's. That's been debunked and labelled a myth, but somehow my brain won't accept that.
So I have it back to front really. Even chromium really is only a problem if you manage to form hexavalent chromium.
Maybe possible if you were to use chrome plated steel in an open fire. Maybe.
