Hardox 450 vs mild steel.40Cr grade under GB/T 3077-2015 standard is a alloy steel bar material.
Hardox 450 vs mild steel, 40Cr alloy chemical composition (C: 0.37 ~ 0.44, Si: 0.17 ~ 0.37, Mn: 0.50 ~ 0.80, Cr: 0.80 ~ 1.10, Ni: ≤0.30, P: ≤0.030, S: ≤0.030, Cu: ≤0.30, Mo: ≤0.10). Heat treatment: First quenching heating temperature (℃): 850; coolant: oil; Temperature heating temperature (℃): 520. 40Cr steel tensile strength (σb / MPa): ≥980. Yield point (σs / MPa): ≥785With the increase of temperature, the yield limit of will decrease monotonically, but the tensile strength of will rise to a high peak value at a certain temperature, and then decrease. This peak temperature is called the blue brittleness temperature of . Near the blue brittleness temperature, the strength increases and the plasticity decreases. The elongation and section shrinkage of increase with the increase of temperature, but there is a low peak at the blue brittleness temperature The blue brittleness temperature of low carbon steel ranges from 200 ℃ to 250 ℃ The blue brittleness of low alloy steel is not obvious as that of low carbon steel, and the blue brittleness temperature is higher,

Hardox 450 vs mild steel., modified steel shipping containers are being used to construct the Ras Abu Aboud stadium in Qatar for the 2022 Fifa World Cup. The stadium’s modular design, the first of its kind to be used for a World Cup. Designed by Fenwick Iribarren Architects, the stadium’s principle structure is formed of a steel frame similar to those used in large scale warehouse projects. This frame will be divided into sections allowing for modified shipping containers to be used as the main building blocks.
