Q500D steel plate belongs to low-alloy high-strength structural steel plate. The implementation standard of Q500D steel plate is GB/T3247 standard. The delivery state of Q500D steel plate is quenched and tempered (quenching + tempering), and the delivery state can also be specified according to technical requirements.
Q500D steel plate thickness direction performance requirements: Z15, Z25, Z35.
Requirements for flaw detection of Q500D steel plate: first inspection, second inspection, third inspection.
Q500D steel plate density: 7.85/cubic meter.
Q500D steel plate production and cutting process
Production process: primary refining→LF refining→VD treatment→continuous casting (die casting)→cleaning, heating→rolling→(stacking)→surface inspection→batching→flaw detection→heat treatment→cutting and sampling→performance inspection→
Q500D steel plate cutting process
After the factory inspection of Q500D steel plate, the performance indicators meet the requirements, and the cutting process can be carried out. It can be cut and drawn.Generally, when the thickness of the steel plate is not greater than 20mm, it is preferred to use CNC plasma cutting or CNC laser cutting. If the thickness of the steel plate is greater than 30mm or more , usually choose CNC flame cutting, which can control the cutting accuracy and time.
