How To Make Hardened Steel In Conan Exiles: The Ultimate Crafting And Resource Guide

To make Hardened Steel in Conan Exiles, you must combine one Steel Bar with one unit of Black Ice inside a Furnace or Improved Furnace. This Tier 3 metallurgical process requires a minimum level of 50 to unlock the necessary feats, though the materials can be gathered earlier if you possess the appropriate cold-weather gear and tools.

Strategic Pre-Operation Requirements and Equipment Checklist

Advancing to the Hardened Steel tier marks a significant transition from the mid-game to the late-game in Conan Exiles. Unlike basic Steel, which relies on chemical additives to carbonize Iron, Hardened Steel utilizes the unique properties of Black Ice found in the frozen northern reaches of the Exiled Lands. Before attempting to mass-produce this alloy, you must secure a stable supply chain of precursor materials and specialized crafting stations to ensure efficiency.

Effective planning requires understanding that Hardened Steel is the fundamental requirement for crafting Star Metal tools and high-tier Cimmerian or Epic-grade armors. Without a streamlined production line, your progress will stagnate as you encounter resources that basic Steel tools cannot efficiently harvest.

Essential Gear and Material Checklist:

• Mandatory Crafting Stations: Furnace, Improved Furnace, or Improved Furnace (Kiln).
• Ancillary Stations: Firebowl Cauldron (for Steelfire production) and a Tannery (for Tar production).
• Prerequisite Feats: Steel Tools (Level 30) and Hardened Steel Tools (Level 50).
• Primary Ingredients: Ironstone, Steelfire (Tar + Brimstone), and Black Ice.
• Environmental Protection: Cold-resistance armor (Vanir, Cimmerian, or God-breaker sets) and Spicy Foods/Mulled Brew to survive the Frozen North.
• Estimated Duration: 20–30 minutes for a dedicated resource run, followed by 10–15 minutes of smelting time per stack of 100 bars (variable by Furnace tier).

The Hardened Steel Smelting Workflow: A Step-by-Step Execution

The production of Hardened Steel is a multi-stage industrial process. You cannot simply find Hardened Steel in the wild in significant quantities; it must be forged through a rigorous sequence of gathering, refining, and alloying. Follow these steps to establish a high-yield production line.

Step 1: Harvesting Ironstone and Producing Iron Bars

Every piece of Hardened Steel begins as basic Ironstone. You can find high-density Iron deposits throughout the Highlands and the Desert. Once harvested with a Pick (preferably Steel or better), place the Ironstone into a Furnace with a fuel source like Coal, Oil, or Dry Wood.

• The Ratio: 2 Ironstone yields 1 Iron Bar.
• Optimization: Use a Smelter Thrall (Tier 3 or 4) to increase the conversion speed and reduce fuel consumption.

Step 2: Manufacturing Steelfire in the Firebowl Cauldron

You cannot skip the Steel phase to reach Hardened Steel. To turn Iron into Steel, you need Steelfire. This is a chemical catalyst created by combining Tar and Brimstone in a Firebowl Cauldron.

• Tar Acquisition: Produced as a byproduct in the Tannery when processing Hides into Leather.
• Brimstone Acquisition: Harvested from the Shattered Springs (gas mask required), Sinner’s Rise, or the caves along the southern river.
• The Recipe: 2 Tar + 1 Brimstone = 1 Steelfire.

Step 3: Smelting Standard Steel Bars

Combine your Iron Bars and Steelfire in any Furnace. This is the foundation of your future alloy.

• The Recipe: 5 Iron Bars + 1 Steelfire = 1 Steel Bar.

• Pro-Tip: If you are using an Improved Furnace or higher, the crafting speed is significantly increased. Always prioritize upgrading your furnace before beginning large-batch Hardened Steel production to save real-world time.

Step 4: The Black Ice Expedition

Black Ice is the "hardener" in this recipe. It is found almost exclusively in the Frozen North, specifically within the Temple of Frost and the surrounding mountain peaks like Skyfall Ridge.

• The Harvest: Use a Steel Pick or better on the glowing blue crystalline nodes.

• Warning: The Temple of Frost is guarded by Frost Giants and contains the "Extremely Cold" environmental debuff. Without proper Cold Resistance (at least 2-3 bars on your character sheet), you will suffer Frostbite and die within seconds. Carry a Torch or consume Spicy Chili to mitigate the cold.

Step 5: Final Synthesis of Hardened Steel

Once you have returned to your base with Black Ice and have your Steel Bars ready, place them both back into the Furnace.

• The Recipe: 1 Steel Bar + 1 Black Ice = 1 Hardened Steel Bar.
• Note on Legacy Recipes: Older versions of Conan Exiles used a recipe involving Brimstone for Hardened Steel. In the current version of the game, Black Ice is the mandatory and only ingredient for this transition.

Furnace Efficiency and Material Conversion Benchmarks

The type of furnace and the quality of the thrall assigned to it will drastically alter your output. The following table illustrates the performance metrics for different smelting stations when producing Hardened Steel.

Common Smelting Failures and Resource Management Fixes

Even experienced players can encounter bottlenecks or errors in the Hardened Steel production chain. Identifying the root cause of a stalled furnace is essential for maintaining base defenses and gear quality.

The Furnace Is Not Consuming Resources

• Root Cause: This usually occurs if the player is using the outdated recipe (Steel + Brimstone) or if the furnace lacks a valid fuel source.
• Actionable Fix: Ensure you have Black Ice in the inventory, not Brimstone. Check that the "Play" button (Start) at the top of the furnace inventory is toggled on and that fuel (Coal, Wood, Oil) is present and burning.

Inadequate Black Ice Yields

• Root Cause: Using low-tier tools or lacking the "Hard Worker" perk from the Strength attribute tree.
• Actionable Fix: Use a Steel or Hardened Steel Pick. Invest points into the Expertise attribute to unlock the "Efficient Harvest" perk, which doubles the amount of rare resources gained from nodes like Black Ice.

Death by Frostbite During Resource Runs

• Root Cause: Insufficient "Cold Protection" stats on armor or failing to account for the "Chilled" status effect during combat.
• Actionable Fix: Craft a set of Cimmerian Fur armor or Vanir Heavy armor. Carry "Spicy Haunch" (crafted at a Stove) to provide a temporary internal heating buff that stacks with your armor’s resistance.

Steelfire Production Bottleneck

• Root Cause: A lack of Tar due to inefficient Tannery management or a lack of Brimstone.
• Actionable Fix: Build multiple Tanneries and fill them with Thick Hide (which yields more Tar than regular Hide). For Brimstone, perform a "naked run" to the Shattered Springs with a horse and a large backpack to clear out the area in one trip.

Frequently Asked Questions

What is the fastest way to get Black Ice for Hardened Steel?

The Temple of Frost is the most concentrated source of Black Ice in the game. By entering the main hall and mining the pillars and floor nodes, you can yield several thousand units of Black Ice in a single five-minute run, provided you can fend off the Frost Giants.

Can I make Hardened Steel without going to the Frozen North?

While you cannot mine Black Ice in the desert, you can occasionally obtain Hardened Steel bars by raiding high-level Cimmerian NPCs at Mounds of the Dead or by looting chests in elite dungeons like the Sunken City. However, this is not a sustainable method for mass production.

Does a Smelter Thrall change the Hardened Steel recipe?

No, a Smelter Thrall does not change the ingredients required for Hardened Steel, but a Tier 4 (Legendary) Smelter will significantly increase the smelting speed and reduce the fuel cost per bar, making your overall operation much more resource-efficient.

At what level should I start making Hardened Steel?

While the recipe is technically available as you approach level 50, you should start preparing at level 40. This gives you time to craft cold-resistant gear and establish a base closer to the Highlands, reducing the travel time between the Black Ice nodes and your furnaces.

Why is Hardened Steel better than regular Steel?

Hardened Steel tools have significantly higher durability and resource harvest multipliers. Furthermore, Hardened Steel is a mandatory component for crafting "Master" level weapon and armor kits, which are required to survive the game's final dungeons and boss encounters.

Master the Forge of the Exiles

Now that you have the technical knowledge to produce Hardened Steel at scale, you can dominate the harsher climates of the North and craft the weapons necessary to defeat the most dangerous legendary creatures. Ensure your furnaces are always stocked with Black Ice and Steel to maintain a competitive edge in your journey across the Exiled Lands.
