Difference Between Mild Steel and High Tensile Steel

Jun 27, 2019 · Mild steel is a very common type of carbon steel, which has a low amount of carbon by weight. High tensile steel is a type of mild carbon steel which has a high yield strength and tensile strength. So, the key difference between mild steel and high tensile steel is that high tensile steel has a high strength than mild steel. High-temperature material degradation of Q345 cold The reduction factors of the elastic modulus and yield strength predicted by AS 4100 are obviously overestimated for the current Q345 CFS, and the reduction factors of the yield strength predicted by EC 3 are also non-conservative for the current Q345 CFS when the maximum or load testing temperature is lower than 600 °C.
