Cast Steel vs Forged Anvil
Quick answer
For a beginner, a cast steel anvil is the right buy: it delivers 65-80% rebound and a hardened face at a fair $2-4 per pound. Forged steel anvils rebound a little higher and last a lifetime, but cost $7-12+ per pound. Avoid cast iron entirely - it is a soft, brittle 'anvil-shaped object' with dead rebound, worth no more than scrap.
Cast Iron, Cast Steel, and Forged: Three Different Tools
Walk through any online marketplace and you will find 'anvils' priced from $40 to $900, and the word covers three very different tools. The cheap ones are usually cast iron doorstops. The sensible beginner buys are cast steel. The premium pieces are forged steel. Material and manufacturing decide the three things that actually matter at the anvil: rebound (how much hammer energy bounces back into your steel instead of dying in the face), face hardness (how well it resists denting and marring), and edge durability.
This page compares all three, ties the result to a fair price per pound, and tells you which one a first-year smith should actually spend money on. The short version: cast steel is the beginner's value pick, forged is a lifetime upgrade, and cast iron is not an anvil at all.
First, Rule Out Cast Iron
Before you compare cast steel and forged, eliminate the impostor. Most sub-$100 'anvils' are cast iron, known in the trade as an ASO - anvil-shaped object. Cast iron is cheap to pour but brittle and soft: a hammer blow dies in the face instead of bouncing back, so rebound sits around 10-30% and the face dents, chips, and mushrooms under real work.
A magnet will not save you here - iron and steel are both magnetic. The tells are price and behavior: rock-bottom $/lb, a rough sand-cast surface, no heat-treat claim, and a dull thud instead of a ring. Do not pay more than about $1.50/lb for anything you suspect is cast iron, and honestly, do not buy it at all. A length of railroad track is a better free starting point than a cast iron doorstop. Run any candidate through the price-per-pound calculator before you commit a dollar.
| Material | Typical rebound | Face hardness | Price/lb (US) | Beginner verdict |
|---|---|---|---|---|
| Cast iron (ASO) | 10-30% | Soft, dents easily | Under $1.50 | Skip - not an anvil |
| Cast steel | 65-80% | ~48-52 HRC | $2-4 (budget) | Best value pick |
| Mid-tier steel | 75-85% | ~50-56 HRC | $4-7 | Great if budget allows |
| Forged steel | 80-90% | ~52-58 HRC | $7-12+ | Lifetime upgrade |

Two anvils show the split cleanly: a 132 lb cast steel anvil that gives a beginner all the mass and rebound they need at a fair price, and a mid-tier steel anvil that steps up face hardness, edge quality, and rebound for smiths ready to invest more. Cards, specs, and current pricing load below.

How They Are Made (and Why Rebound Changes)
Cast steel starts as molten steel poured into a mold, then heat-treated so the face hardens. Casting lets makers produce a full anvil shape - horn, face, hardy hole - affordably, and modern cast steel anvils reach a genuinely hard, high-rebound face in the 65-80% range. The trade-off is that cast structure can be slightly less tough at the edges than forged, so sharp corners may chip if you abuse them.
Forged steel is different. A billet of steel is worked under a press or power hammer, which aligns the grain and refines the structure before the face is hardened. That grain flow is why forged anvils lead on rebound (often 80-90%), edge durability, and impact toughness. It is also slower and more labor-intensive to make, which is the whole reason forged anvils cost $7-12+ per pound while cast steel sits at $2-4. With forged, you are paying for process, not just material.
Which One Should a Beginner Buy?
For almost every beginner, cast steel is the right answer. It delivers the rebound and hard face you need to forge efficiently, at a price that lets you buy real mass. Mass is what actually moves metal, so spend your budget on weight first. Use the anvil weight calculator and the 40-50x hammer-weight rule to size it - a 2 lb beginner hammer pairs well with roughly an 80-100 lb anvil, and a 132 lb cast steel anvil gives you comfortable headroom for years. See our best beginner anvil and budget anvil picks for specific weight-and-price sweet spots.
Forged is the lifetime upgrade. If you already know you will forge for decades, do heavier or professional work, or simply want the best tool you can own, a forged anvil rewards you with slightly higher rebound, better edges, and strong resale value. It is rarely the smartest first purchase, though - most smiths are better served putting that money into more cast steel weight now and upgrading to forged later.
Test the Anvil and Watch the Freight
Whatever you buy, test the actual anvil, because the label lies more often than the steel does. Drop a 1 in (25 mm) ball bearing from about 10 in (25 cm) onto the face and watch the bounce: a real anvil returns 70% or more, while a dead thud is cast iron. Tap the face and listen for a clear ring. Be skeptical of hardness numbers - unless the listing states a heat-treated face and gives an HRC figure, assume it is soft.
Finally, budget for freight. Anvils are dense, and shipping a 132 lb block can add $50-150 or more, which quietly changes your true price per pound. Once it arrives, mount it solidly - a well-mounted anvil rebounds better and moves less, so read how to mount an anvil before your first session.
Frequently asked questions
Is a cast steel anvil good enough for a beginner?
Yes. Cast steel anvils are heat-treated to a hard face and typically return 65-80% rebound, which is plenty to forge efficiently for years. The main practical difference versus a forged anvil is edge durability and top-end rebound. For a first anvil in the 66-132 lb range, cast steel gives you the most usable mass per dollar. Buy the weight, not the badge.
How do I tell cast iron from cast steel?
You cannot tell by magnet - both are magnetic. Judge by rebound and sound instead: cast iron thuds and a ball bearing barely bounces (10-30%), while steel rings and returns 70% or more. Cheap unbranded 'anvils' under about $2/lb, especially with a rough sand-cast look and no heat-treat claim, are almost always cast iron ASOs. Ask the seller for the material spec.
Is a forged anvil worth the extra money?
For a hobbyist, usually not as a first purchase. Forged anvils offer the best rebound, toughness, and edge retention, and they hold value, but you pay $7-12+ per pound for a modest gain over a good cast steel anvil. If you forge daily, do heavy work, or want a buy-it-for-life tool, forged is the upgrade. Otherwise, put the money into weight first.
What rebound percentage should an anvil have?
Aim for 70% or better. Drop a 1 in (25 mm) ball bearing from 10 in (25 cm) onto the face; a 7 in (18 cm) bounce is 70%. Good cast steel lands around 65-80%, forged around 80-90%, and cast iron ASOs around 10-30%. Higher rebound means more of each hammer blow moves your steel instead of your arm.
Does anvil material matter more than weight?
Weight matters first, then material. A heavier anvil resists moving and returns more energy, so a 132 lb cast steel anvil will out-forge a 75 lb forged one for most beginners. Use the 40-50x hammer-weight rule to size it, then pick the best material you can afford at that weight. Both matter, but mass is the foundation you build on.
