Tensile Strength of Steel vs Yield Strength of Steel
Tensile strength is the resistance of steel to breaking under tensile tension It s used to specify the point when steel goes from elastic temporary to plastic permanent deformation Usually it s measured in units of force per cross sectional area Once a piece of steel is pulled past its tensile stress point it will split apart
What is Tensile Strength
A particular material s response to tension stress that is the force from an axial pull depends on the nature of the said material Some materials exhibit an abrupt fracture when the tensile capacity is reached Others meanwhile show deformation or necking before completely breaking apart In alloys tensile strength is influenced by composition such as the amount of carbon …
