Yield Strength vs Tensile Strength of Steel and Other Metals

While welders often prioritize tensile strength, understanding both yield and tensile strength is crucial for metalwork. Yield strength indicates when a material begins to permanently deform, while tensile strength is the maximum stress it can withstand before breaking. This post defines both, explains their behaviors, and highlights their importance in design, using a bridge example to illustrate how a structure can deform without catastrophic failure if loads exceed yield but not tensile strength.
