European standard high-strength structural steel S500Q and S500QL steel

S500Q is European standard high-strength structural steel, referred to as high-strength steel. The phosphorus and sulfur content of S500Q and S500QL are different. The phosphorus and sulfur content of structural steel S500Q is P: ≤ 0.025, S: ≤ 0.015, the sulfur and phosphorus content of S500QL steel is P: ≤ 0.020, S: ≤ 0.010, the impact temperature is also different, S500Q steel is -20℃ impact, S500QL is -40℃ impact. S500Q and S500QL steel executive standard: EN10025-6.

European standard high-strength structural steel S500Q and S500QL heat treatment delivery status: quenched and tempered.

S500Q and S500QL steel smelting methods:
Converter / electric furnace steelmaking → LF furnace refining → VD furnace vacuum degassing → continuous casting / die casting / electroslag → cleaning and heating → rolling → flaw detection → heat treatment → steel plate finishing → sampling → performance inspection.
