hardox 400 specification specification
Q690D material is a Chinese standard high-strength welded structural steel. What does Q690D stand for? Q represents the yield strength, 690 represents the yield strength value, and D represents the quality of the Q690 steel. The quality grades are A, B, C, D, and E, respectively. The impact of Grade D steel plate is﹣20°C. Q690D executive standard: GB / T1591-2008. HARDOX 400 specification, Q690D steel has high yield strength and tensile strength.
The chemical composition of 20CrMo steel pipe is 0.17-0.24, Si: 0.17-0.37, Mn: 0.40-0.70, Cr: 0.80-1.10, Mo: 0.15-0.25. Mechanical properties of 20CrMo steel pipe: tensile strength 410 Mpa; yield strength: 265mpa; elongation after fracture: 24; reduction of area: 60; impact absorption energy: 110J. 20CrMo steel pipe belongs to alloy structure steel pipe, which has high thermal strength, good high-temperature strength, good machinability, medium cold bending plasticity, high hardenability and good welding performance at 500-520℃. HARDOX 400 specification, 20CrMo steel pipe is generally used in quenching and tempering state.
