Steel Plate Introduction

BV/E690 and BV GRADE D690：BV/E690 steel plate and BV GRADE D690 steel are types of high - strength steel. The BV GRADE D690 is an extra - high - strength steel. These steels are often used in applications that require high strength and good mechanical properties to withstand heavy loads and harsh working conditions.

Tempering and Quenching：Tempering and quenching are heat - treatment processes. Quenching involves rapidly cooling the steel from a high temperature to increase its hardness. However, quenching alone can make the steel brittle. Tempering is then carried out after quenching. It involves reheating the quenched steel to a lower temperature and then cooling it at a suitable rate. This process helps to reduce the brittleness caused by quenching and improve the toughness and ductility of the steel while still maintaining a high level of strength.

Mechanical Properties and Applications

Applications：These steels are widely used in the construction of heavy - duty machinery, such as mining equipment, cranes, and offshore structures. In the mining industry, for example, the buckets of large excavators and the frames of heavy - duty dump trucks need to withstand extremely high loads and impacts. The high strength of BV/E690 and BV GRADE D690 steels can meet these requirements. In offshore applications, such as the construction of oil platforms, the steel's ability to resist the corrosive marine environment and high - strength requirements for withstanding wave and wind loads make it a preferred choice. They are also used in some high - strength structural components in the construction of large - scale buildings and bridges, especially in areas where space is limited and high - strength materials are needed to reduce the size and weight of structural members while still maintaining the required load - bearing capacity.
