Calculations
Armor Values
Steel Fiber gives additional Armor based on the frame's Base Armor.
The Total Armor can be calculated by the following formula:
Total Armor = BaseArmor * (1 + SteelFiberPercent)
Example - 190 Base Armor with 110% Steel Fiber would be calculated as follows:
Total Armor = 190 * (1 + 1.10) = 399 Total Armor
Damage Mitigation
Damage Mitigation is the amount off the total damage that armor reduces, and is calculated as:
Damage Mitigation = Total Armor / (Total Armor + 300)
The following table shows the net Damage Mitigation percentage values provided by armor for different key base armors that various frames have.

Effective Health
Higher armor values can be thought of as increasing your effective health in relation to incoming damage. However, this would only apply to damage types that do not ignore armor. Because "effective health" more literally translates as "the maximum amount of damage you can take", if we simply set your "Total Health" equal to your "Incoming Damage" after Damage Mitigation, and then solve for the Incoming damage alone, we can determine your Effective HP.
Total Health = Incoming Damage * Damage Mitigation % Total Health / Damage Mitigation % = Incoming Damage
As Armor Increases, Damage Mitigation values decrease, and therefore Effective HP drastically increases. Below are two tables with examples of how Effective HP increases with armor. All values are rounded to the nearest integer.

Notes
- Armor (and thus Steel Fiber) will only mitigate damage to Health.
- This mod does not improve Shields or Iron Skin (though the latter is affected by Power Strength).
- As Snow Globe gains additional health from Frost's armor, Steel Fiber affects it.
Tips
- This mod is generally more effective on frames with 100 armor or greater.
- Steel Fiber is most effective when used on Valkyr as she has 600 armor, the highest value of any Warframe.
Trivia
- The mod image is actually that of Rhino's Iron Skin prior to Update 9.5, which updated the effect to its current appearance.
