I Forge Iron

Question on metal type


Recommended Posts

I have an opportunity to tack onto our companies steel order. I can order whatever steel I need and the vendor will bundle my order separate from the companies, they only need to know what material codes I want, size and length. I have read a lot of posts here and saw many descriptions of what steel we can use (tie rod ends, coil spring, leaf springs etc). Can you please help with the ASTM numbers that work for Blacksmithing?

 

 I came up with this list:

1080/1084/1095/1040/1045/1030/5160/1018/ 

Does it matter hot or cold rolled?

hot/cold rolled in a process.    You will find cold rolled costs more, and after it gets hot in the forge is the same as hot rolled anyway.  1018 is good for general smithing.  1084 for blades.  I use 1045 for many anvil tools and stake anvils as well.

What do you want to make?

For most decorative forged work hot rolled mild steel is fine. In the UK it is often referred to as merchant bar or general merchant quality. It is for non critical structures and uses.

If you are wanting tougher or harder stuff for edge tools or critical structural elements do not trust a response from the internet without further research.

Maybe ask your supplier's advice?

Im looking for general steel for use on crafts no tooling. I was looking towards 1018 as it is only $1.00 for a three foot section. What about A36 steel, this came up as hot rolled. The 1018 is cold rolled.

Well A36 is not what I would call "mild steel" but is often sold as such.  Things like 1018 have a fairly strict content spec: 18 points carbon and nothing above tramp elements save for Iron and Manganese; A-36  is a yield strength spec---36 Kpsi and it can have a much more variable content.  However it's cheap and so that is what most of use/get.  Some folks spring for the real 1018 if they have a project where they really need to depend on the forgability.  I've had A36 that was a joy to forge and A36 that was good only for tentstakes.

So I have the option to purchase material certified 1018 or A36. I was looking at the .25"x.50" stock that is 3 feet long. The price for the 1018 is $2.00 a stick and A36 is $1.00 a stick. Would you lean more to one over the other. I am making the typical beginners projects, tongs, hooks etc.

Ask what they charge for a 20' stick and compare the price. Maybe find out what he price per lb. is for cut lengths compared to full sticks is. There IS a cutting charge and that usually makes the difference. If they want to charge you to cut a stick to a size that fits what you drive a hack saw will cut .25"x.5" in about 30 seconds.

So, figure $2.00 x six per stick (in the trade a "stick" is a full length from the mill usually 20') so a full stick should run $12.00 or less. I don't know what you drive but I was able to put 6' lengths in our old Saturn sedan without trouble and if you ask the guys in the yard they'll almost always cut a stick in 2-3 pieces to haul gratis. If you ask the people at the counter when you order they HAVE to charge you so I keep quiet and carry a hack saw just in case.

I've only had to start cutting a length with my hack saw in their loading dock once in 40 years but that's here, no telling what your steel yard rules, formal and informal, are like.

Maybe we have nicer people at the counters here! The reception girl at my steel supplier always tells the boys to cut 6m lengths in half for me to put them in my Landcruiser, and they never charge cutting fees.

Just lucky I guess.

Depends on who you talk to at the counter I guess. It got to where the folk up front couldn't talk with folk out back unless it was on the invoice. I think the bean counters were taking over by then. :unsure:

At the place out here in the Valley I buy from the guy at the counter walks out the door, pulls and cuts stock while talking. I haven't been to the place I used to buy from in Anchorage, last I stopped by most of the guys I knew had retired.

Can you tell me what the most "common" size of metal are? I know many of you use re-purposed metal. But if you had the opportunity to secure new metal stock what sizes would it be. I was thinking 0.50" Sq, 0.25" Sq, .375x.875" and some .25 & .375 round stock.

Also what is the common stock for tongs?

Thanks

Forbidden again! IPS!

The local supplier carries most if not all common stock. My preference is 3/8" sq. hot rolled. next is 1/2" sq. hot rolled. I use 3/8"x3/4" and 1/2"x1" strip stock but not as often. You will find that 3/8" sq and 1/2" round. are almost exactly the same volume per linear inch so buying both isn't necessary unless a specific shape stock is predominant.

For example If I'm making plant hooks with a twist, a leaf or paw print wall finial. I use sq. On the other hand if someone wants round garden furniture that's what I buy. Unless it's a small piece squaring up the round or rounding up the square is wasted time, effort and fuel.

What makes 3/8" sq. my favorite stock is it's the largest I can move by hand easily so the finished pieces have nice weight, there's plenty to form into various shapes and I don't kill myself forging excess steel.

Remember if you double the dimension you are going to have to expend 4x the effort and fuel for the same process.

I forgot you asked about tong stock too. I like coil spring around 1/2" rd. I can make them thinner and because it's spring stock they're stronger for the weight so I don't have to hold as heavy a tool nor squeeze as hard.

I find it difficult to answer your question…depends on your tools and projects.

When the forge was hand and foot powered I used to look at 25mm (1") square on the rack and think it represented a lot of hard work. 

As tooling and projects grew I surprised myself one day by kicking a bit of wire under the bench that I had used as a trial piece in some new press tools and suddenly realised that my perceptions had altered hugely…the bit of wire was 1" square!

Yesterday I was forging down a bit of rusty 100mm x 50mm (4" x 2") to see what the pitting would look like for an armour bright finished fender.

Common size for tongs depends on what you need to hold on to. I agree with Frosty the lighter the better... which is why these have only Ø32mm (Ø1 1/4") reins.

Clifton Ralph told me they only have to be big enough to hold you on the end of the work piece, not the other way around...
