==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:
Example - 190 Base Armor with 100% Steel Fiber would be calculated as follows:
===Damage Mitigation===
Damage Mitigation is the amount off the total damage that armor reduces, and is calculated as:
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.
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.
**As gains additional health from '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 as she has 700 armor, the second highest value of any Warframe.
==Trivia==
*The mod image is actually that of Rhino's prior to , which updated the effect to its current appearance.
