Short answer: Yield strength is the stress at which metal starts to deform permanently and tensile strength is the maximum stress before break; the yield-to-tensile ratio shows ductility and safety margin, and both are specified from the mill certificate to match the load, forming and welding your part needs.
At a Glance
Two Key Numbers
Yield marks the start of permanent set and tensile marks the failure point, with the full map in our Comparación de fuerzas and hardness link in our Hardness Comparison; the carbon base is in our Carbon Steel Supplier page.
Yield-to-Tensile Ratio
A low ratio means more ductility and warning before failure, important for linepipe and structurals, with the design view in our Construction Structural Guide y Bridges Infrastructure Guide.
Forming and Welding
Higher yield means more springback in forming and carbon equivalent (CEV) drives weldability, with forming in our Stamping Guide and welding in our Welding Joining Guide; heat treatment detail in our Heat Treatment Guide.
Reading and Sourcing
The certificate lists both strengths plus elongation; verify with our Mill Test Certificate Guide and inspection in our Quality Inspection Guide, packed per our Export Packing Guide.

Preguntas frecuentes
The stress at which a metal begins to deform permanently rather than spring back.
The maximum stress a metal reaches before it breaks.
A lower ratio gives more ductility and a clearer warning before failure.
Often yes – higher strength alloys tend to have lower elongation.
