The property that makes steel a good choice for sword-making is strength

Explanation:

The strength of a material is its ability to withstand an applied load or force without failure or plastic deformation.  Types of strength of materials include; tensile strength, yield strength, torsional strength, compressional strength, shear strength.

Tensile strength of material is the ability of that material to withstand any force that tends to break or tear it apart. It is calculated by dividing the maximum amount of load or force the material can carry or withstand without breaking by the surface area of the material.

Mathematically, Tensile strength = Force/area

Its unit is Newton per meter squared, N/m².

Yield Strength In Steel

Yield strength is the maximum stress that can be applied before it begins to change shape permanently. Yield strength represents the upper limit of the load that can be safely applied to the meta beyond which it shape deforms.

Steel is an alloy of iron and carbon. It has many important and desirable properties such as durability, hardness and conductivity, and high tensile strength. However, the high strength of steel made a good choice for sword-making in the ancient past and even in the present.
