The yield strength, ultimate tensile strength, hardness and ductility show stability and slight improvement at higher temperature suggesting that this material has high temperature capabilities. The only property that decline with increase in temperature is the impact strength. Importance of Yield Strength & Plastic Deformation to Yield stress is the stress level at the point where the material begins to have permanent deformation, i.e. yield point where the material no longer returns to its original shape and size after the release of the applied stress. However not all material will have a well defined yield region.
