Reasons for choosing Q690D steel

Q690D belongs to low-alloy high-strength structural steel, and Q690D can also be called low-temperature-resistant high-strength steel with a yield strength of 690Mpa, where "Q" represents the first letter of the Chinese pinyin of the word "Qu" for the yield strength of the steel, 690 represents the yield strength value, and "D" represents the grade of the steel plate. Grade of Q690 is divided into B (impact at room temperature), C (impact at 0°C), D (impact at -20°C), and E (impact at -40°C). Q690D steel is Widely used in coal mining machinery, engineering machinery, such as hydraulic supports, port cranes, flatbed transport vehicles, etc.

Q690D steel not only has very high strength, but also has certain flexibility, wear resistance, fatigue resistance, impact resistance, easy processing and wear resistance. Q690D steel is often used in many manufacturing industries and meets the needs of many manufacturing industries. The high-quality performance state of Q690D steel in the process of use has also been deeply loved and praised by the manufacturing industry. Later, due to the recognition of the society, the frequent use of the manufacturing industry and the continuous optimization of the manufacturer, Q690D steel has gradually become one of the commonly used raw materials in the manufacturing industry. one.
