Quenching and tempering (QT) is a double heat treatment process of quenching and high temperature tempering. In general, medium carbon steel and medium 09CuPCrNi-A coil carbon alloy steel often need quenching and tempering treatment. Quenching and tempering can make iron and steel parts obtain a good combination of strength and toughness, with high strength, excellent toughness, plasticity, cutting performance, etc. Some 09CuPCrNi-A coil alloy steel or low alloy steel must be quenched and tempered to obtain good comprehensive properties. These steels can also be called quenched and tempered steels.
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. 09CuPCrNi-A coil, Q690D steel has high yield strength and tensile strength.
