Steel/Calculations
 | This article is suggested to be rewritten. Reason: It would be very useful to have the reasonable optimum steel returns per tick as well as the average ones so we can see what is best in late game colonies. Not theoretical optimums but reasonable ones for example, is deep drilling with a Intellectual 20 scanner and Mining 20, Dual Drill Arms miner better than a 2-archotech-armed smelter, not a Manipulation 355% smelter with every possible bonus. You can help the RimWorld Wiki by improving it. |
Calculations for all items in Steel#Acquisition analysis. Assume healthy pawns in full light in Strive to Survive difficulty. All numbers are rounded to 1 decimal point; unrounded numbers used for all calculations.
Mining steel ore
Relevant stats: Mining Speed, Mining Yield, difficulty.
For 8 Mining skill, healthy pawn :
- 1,900 ticks (31.67 secs) to mine an ore. Mining Speed = 100%. [Verify]
- 40 steel per ore. Mining Yield = 100%.
(1900 ticks / 40 steel) = 47.5 ticks (0.79 secs) per steel.
- Plus travel time.
Deconstruction
Relevant stats: Construction Speed, item in question
For 8 Construction skill, healthy pawn, against a wall:
- 135 ticks (2.25 secs) to deconstruct a steel wall. Construction Speed = 100%.[Verify]
- 2.5 steel per wall. All items give half their steel.
(135 ticks / 2.5 steel) = 54 ticks (0.9 secs) per steel.
- Plus travel time.
Smelting
Relevant stats: General Labor Speed, item smelted
Steel slag chunks
For a healthy pawn:
- 400 ticks (6.67 secs) per chunk. General Labor Speed = 100%
- 15 steel per chunk.
(400 ticks / 15 steel) = 26.7 ticks (0.45 secs) per steel
- Plus travel time.
Weapons and apparel
For a healthy pawn:
- 1,600 ticks (26.67 secs) per item. General Labor Speed = 100%
- 7 steel per autopistol / steel knife. More steel for any other item (25% of item worth)
- You also get any other resources used to craft the item, other than components/advanced components and chemfuel.
(1600 ticks / 7 steel) = 228.6 ticks (3.81 secs) per steel
Shredding
Relevant stats: Mechanoid Shredding Efficiency, Mechanoid Shredding Speed, mechanoid type, Missing Body Parts, whenever done on a machining table
For 10 Crafting skill, healthy pawn:
- 300 ticks (5 secs) to shred a mechanoid. Mechanoid Shredding Speed = 100%. Constant per mechanoid.
- 15 steel per scyther or lancer. 0% Missing Body Parts.
- 5 steel per war urchin -> 2.5 steel @ 50% Missing Body parts
(300 ticks / 15 steel) = 20 ticks (0.33 secs) per steel (0% missing lancer)
(300 ticks / 2.5 steel) = 120 ticks (2 secs) per steel (50% missing w. urchin)
Deep Drilling
Relevant stats: Research Speed, Deep Drilling Speed, Mining Yield
For 8 Intellectual + 8 Mining skill, healthy pawn(s):
- 180,000 ticks (50 mins) average to find any deposit. Research Speed = 100%.
- (4/7.5) = 53% to get steel. 337,500 ticks (93.75 mins) average to find a steel deposit. (not rounded in calculations)
- Average 9000 steel per deposit.
- (180000 ticks * .53 steel / 9000 ticks) = 37.5 ticks (0.63 secs) per steel scan
- 14,000 ticks (3.89 mins) per deep drill cycle. Deep Drilling Speed = 100%.
- 35 steel per deep drill cycle. Mining Yield = 100%.
- (14000 ticks / 35 steel) = 400 ticks (6.67 secs) per steel spent mining.
437.5 ticks (7.29 secs) per steel (scan + mine).
- Plus travel time.
Long-range mineral scanner
Relevant stats: Research Speed, Mining Speed, Mining Yield, difficulty, means of travel
For 8 Intellectual + 8 Mining skill, healthy pawn(s):
- 240,000 ticks (66.67 mins) average to find deposit. Research Speed = 100%.
- Average 2250 steel. Mining Yield = 100%.
- (2400000 ticks / 2250 steel) = 106.7 ticks (1.78 secs) per steel spent scanning.
- 1,900 ticks (31.67 secs) to mine an ore. Mining Speed = 100%. [Verify]
- 40 steel per ore. Mining Yield = 100%.
- (1900 ticks / 40 steel) = 47.5 ticks (0.79 secs) per steel spent mining.
154.2 ticks (2.57 secs) per steel (scan + mine).
- Plus travel time, plus combat time (multiple days w/o transport pods)
Transport pods
Other relevant stats: How you get chemfuel
- 1700 steel per scan.
- 2250 base steel/scan, -550 steel for 8 transport pods + 1 pod launcher, if components are created from steel. (1 pod to arrive, 7 pods + 1 launcher to send 1050kg = 2100 steel).
- (2400000 ticks / 1700 steel) = 141.2 ticks (2.35 secs) per steel spent scanning.
- (1900 ticks / 40 steel) = 47.5 ticks (0.79 secs) per steel spent mining.
- Chemfuel variable work based on how you get it and how far you need to go.
- 33,095.5 ticks (9.19 mins) total to create 350 chemfuel from corn in a biofuel refinery. Enough for a 10-tile trip. Plant Work Speed & Harvest Yield = 100%
- 14,400 ticks (4 mins) to build 8 pods + 1 launcher.
- (14400 ticks / 1700 steel) = 8.5 ticks (0.14 secs) per steel building pods.
216.6 ticks (3.61 secs) per steel (scan + mine + pod + fuel from corn).
- Plus loading time, plus combat time
Transport pods + Farskip

Other relvant stats: How you get chemfuel, psyfocus meditation rate. Assuming you send 2 pawns, which may not exactly be safe.
- 2188 average steel per scan. 1 transport pod (-62 steel) to location.
- (2400000 ticks / 2188 steel) = 109.7 ticks (1.83 secs) per steel spent scanning.
- (1900 ticks / 40 steel) = 47.5 ticks (0.79 secs) per steel spent mining.
- 1,600 ticks (26.67 secs) total to build 1 pod. 2,500 ticks (41.67 secs) + 1,177.3 ticks (19.62 secs) total for 35 chemfuel fueled from corn (15 tile trip).
- 1.4 full days (84000 ticks) for 70% psyfocus at 50% psyfocus per day. (70% / [psyfocus per day]) days for 60000 ticks = 1 day.
- Meditation also counts as Recreation.
- 38.4 ticks (0.64 secs) per steel meditating for farskip. 50% psyfocus per day.
- (1900 ticks / 40 steel) = 47.5 ticks (0.79 secs) per steel spent mining.
198 ticks (3.3 secs) per steel (scan + mine + pod + fuel from corn + meditation).
