Product Description
Q690D Q690E Steel Plate
1: Q690D Steel Introduction
Q690D is a high-strength steel plate, mainly composed of ferrite and pearlite. Among them, ferrite is the soft phase and pearlite is the hard phase, and this two-phase organization makes Q690D have better toughness and strength at the same time. In addition, Q690D also contains a small amount of bainite and martensite.Q690D steel plate has high strength and hardness, its tensile strength and yield strength can be up to more than 1,000MPa and more than 800MPa respectively. At the same time, Q690D also has good toughness and ductility, and its elongation and impact toughness are high. These excellent mechanical properties enable Q690D to meet a variety of complex and demanding applications.
