Mill Test Report(MTR)
A mill test report (MTR) is a quality document provided by a metal manufacturer that certifies the chemical composition and mechanical properties of a batch of metal. Required for aerospace, defense, and many industrial applications.
Tensile Strength(UTS)
Tensile strength (ultimate tensile strength, UTS) is the maximum stress a material can withstand while being stretched before breaking. It is a key property listed on mill test reports.
Yield Strength(YS)
Yield strength is the stress at which a metal begins to deform permanently. Below the yield point, deformation is elastic and reversible; above it, the metal is permanently bent or stretched.
