The ultimate tensile strength of 400 grade structural mild steel is about
A. 160 N/mm2
B. 260N/mm2
C. 420 N/mm2
D. 520N/mm2
Answer: Option C
Solution (By Examveda Team)
The ultimate tensile strength of a material refers to the maximum amount of tensile (pulling) stress it can withstand without breaking. For 400 grade structural mild steel, the ultimate tensile strength is approximately 420 N/mm2. This property is essential in engineering and construction applications where the material's ability to bear loads and resist deformation is crucial.Join The Discussion
