Steel Ingot

Steel Ingots are items found in The Pitt DLC pack for Fallout 3. Finding all 100 gives you the Mill Worker achievement.

Abandoned Area (3)

 * 1) In the Abandoned Area before you head to the Steelyard, to the left there is a mine cart with 3 ingots in it. (Note: The first time you enter, these ingots will be inaccessible. After obtaining at least 10 ingots from outside, returning to the room will reveal a Trog has torn a hole in the fence, allowing you access to the mine cart.)

Steelyard (79)

 * 1) There are 2 ingots as soon as you enter the steelyard next to the dead slave.
 * 2) You will find 2 in the first dumpster to the left by the the trailer with the couch on top of it.  You can access this dumpster by jumping over from the roof of the truck.
 * 3) There are 2 ingots in the 2nd dumpster to the left.  You can access this dumpster by jumping over from the roof of the nearby building to the far dumpster.
 * 4) There are 3 in the smaller dumpster next to the 3rd large dumpster on the left, there’s a dead slave in there as well.
 * 5) Head up the stairs by the dumpsters, after you hop the broken fence, go right then, turn left.  There are 2 of them in between the 2 knocked over barrels.
 * 6) Go north along the ledge, outside the fence. Looking down you should see 2 on top of a freight car in the middle. Carefully jump onto the third steel beam from the end (this is the one you need to climb on to get to the ones in #8 below) and walk out till you get to the freight car with the 2 ingots on it. Drop down and they’re yours.
 * 7) Now head back up to where you dropped down on the freight car. This time continue across the steel beam to the end and drop down into the dumpster for 3 more.
 * 8) Once again head back up the stairs but instead of going right go left, there is a small building to your right there are 2 of them sitting on a shelf. If you open the gate you went too far.
 * 9) After you get the two in the small building head through the gate and go straight till you see a large dumpster. Climb up the stairs on top of the building on your left.  Take a run off the end of the roof and drop down into the dumpster.  There are 2 in there.  If you get between that round generator thing in the dumpster and some concrete blocks, you can get stuck, so the old adage to "save early, save often" definitely applies in this quest.
 * 10) Now jump from the dumpster over the barbwire fence to the south head right until you reach a dead end. There is a dead slave and 2 ingots.  It may be easier to jump to the fence to the west first before jumping south.
 * 11) Jump on top of the generator just behind you to find a plank and climb back over the fence and head back up the stairs till you reach the roof. Looking down in between the buildings you should see another set of stairs and 2 more ingots. Careful of the 3 Trogs waiting to attack you.
 * 12) Follow the path until you get to a gate.  Open the gate and go out to the left. Go down the hill to the end where there is a ditch and a dead slaver. There are 3 laying next to him. Make sure to bring some Rad-X and grab the Gamma Shield Armor off the dead slaver.
 * 13) Turn to your left and continue into the radiated barrels there are 3 more in the middle.  Note that you can kill the 1 or 2 Trogs who hang out in this area from the other side of the fence. This is recommended because this is not a good area to get into a firefight in if you're not prepared for the radiation.
 * 14) Go back up to the stairs and jump on top of the small roof, then cross the wooden planks to the next building.  Go to the end of that building's roof and you will see a makeshift bridge crossing over to other buildings. There are 2 in the middle of the bridge.
 * 15) Once you get the 2 on the bridge continue across to the other side. Stay on top of the building and head to the back there will be 2 more sitting on a roof you can drop down to.
 * 16) After you get the 2 on the roof drop all the way down to the ground, there are 2 more sitting on a shelf.
 * 17) Head around the corner behind the stairs where you will find 2 more behind the tires.
 * 18) Head south till you can’t go anymore and you see a set of stairs to the right. Climb the stairs and there are 2 on the first landing next to a dead slave named Wild Bill (if you haven't already, speak to the slave named Milly about Wild Bill's fate).
 * 19) After you find Wild Bill continue up the stairs where there will be a makeshift shack with 3 wild men inside.  Kill them and take the 2 ingots by the fridge on the floor.  Note that on the other side of this shack is a door that you can access later; Wehner's hideaway.
 * 20) Facing away from the Wildman shack, follow the metal catwalk as it cross over a big pipe and turns left.  You should see a few Trogs waiting to ambush you on the perpendicular pipe.  A well-placed grenade can knock all three off the pipe.  Continue on the catwalk until it crosses under the same pipe the Trogs were on, then jump onto the pipe which runs parallel to the catwalk.  As the pipe turns right, you will see a Trog Brute waiting at the end.  Dispatch him and there will be two ingots in the pile of guts he was feeding on.
 * 21) Turn around and get back onto the catwalk where the pipe bends.  At the wooden planks, drop down to the building below and go the end of the roof and drop down to the ground.  Go north around the corner of the building and then left down the narrow alley.  You should see an upright mining cart containing 4 ingots, a med kit and an ammo box.  Watch out as there will be some Trogs and maybe wildmen, if they haven't killed each other off yet.
 * 22) Now head east (facing east its the wall to the left not the wall that runs down the alleyway you just came down) along the wall to the right. You'll end up following a fence. Follow it  to the right till you reach a dead end. There will be a dead slave with a combat shotgun and 2 ingots next to him.
 * 23) Go all the way back up the stairs past the Wildman shack, along the catwalk to to where you dropped down from, keeping going across the roof and take the stairs that take you up to the top of the factory building. Turn left at the top of the stairs and take the first right you can. There are 4 of them back right hand corner by the dome and dead slave.
 * 24) Now go back and climb the stairs to the very top of the structure you’ll hit the mother load of 12 ingots on the end of the catwalk.  Be prepared for a tough fight with 4-5 Wildmen above and Trogs coming from below.
 * 25) On your way back down you’ll see a really large and long conveyor belt, drop down on there and follow it to the end for 7 more ingots.
 * 26) Head back up to the rooftops with the domes on it.  Head all the way south till you get to the wall turn left and drop down it’s a long drop but you won’t die (If you push against the large pipe running down the wall it should break your fall into smaller jumps and you'll reach the bottom unharmed. Get to this pipe by carefully slipping around the chain link fence. Med-X isn't a bad idea before making this drop).  Now you’ll need to drop down to the next platform with the 3 big silos on it. Head all the way east and and turn right at the fence. There will be a dead slave with an Auto-Axe next to him. There will be 4 of them.  There are also at least 4 Trogs, coming from both directions, so be prepared.
 * 27) Head back down to where all the freight cars are. There are 2 ingots at the end of the tracks by the collapsed tunnel.

Supply Plant (18)

 * 1) Back by the freight cars there are a bunch of Protectrons lined up and a door. Enter the Supply Plant and head down the hallway.  In the second room you’ll come across 3 ingots.
 * 2) Continue on to the lower level of the factory. Go down the hallway on the right and follow the tracks all the way to the end. You’ll come across a couple of madmen and a bunch of dead Trogs there are 8 of them in an overturned mine cart.
 * 3) Now head down the hallway to the left and you will come across a door on your right and two dead madmen with bobby pins laying everywhere. Pick the lock on the door to find a nice supply of ammo and 6 ingots.
 * 4) Continue up the stairs until you reach a room with a bed. There will be a unique Auto-Axe, the Man Opener, on the bed and to the right is the final Ingot.
