While you are progressing through the building and creating aspects of Astroneer, you will undoubtedly run into the issue of needing steel. Steel is used for cranes, hydrazine thrusters, as well as an entire list of other important things. Luckily, it isn’t too difficult to get, and this article will show you exactly how to get it.
Before I go into the list of materials you need, you will need a chemistry lab. The chemistry lab is going to be your catalyst for making steel.
The first material you will need is carbon. Carbon can be made by smelting organic on your smelter.
The next Item on the list is argon. Argon can be obtained if you travel to Glacio and collect it with your atmospheric condenser.
Lastly, you will need Iron. You can easily find hematite on the surface of Glacio. I usually mine the hematite while I am collecting the argon. Go back to your base and smelt it to make Iron.
The last step is to place the items in the chemistry lab and press start!
