WebNov 4, 2024 · What is the allowable stress for mild steel? The ultimate strength, or stress of mild steel is around 800 to 840 MPa. So, taking a factor of safety of 4 (four) , the allowable stress works out to 800 ÷4 =200 MPa. What is allowable stress? Allowable stress, or allowable strength, is the maximum stress that can be safely applied to a … Ultimate strength is an attribute related to a material, rather than just a specific specimen made of the material, and as such it is quoted as the force per unit of cross section area (N/m ). The ultimate strength is the maximum stress that a material can withstand before it breaks or weakens. For example, the ultimate tensile strength (UTS) of AISI 1018 Steel is 440 MPa. In Imperial units, the unit of stress is given as lbf/in² or pounds-force per square inch. This unit is of…
