EN 10025 S550QL high strength steel is required to have high toughness

ASTM A242 has 2 grades: Type 1 and Type 2, while type 1 is the most used structural steel grade. Usually EN 10025 S550QL high strength steel it is produced to be hot rolled state, it is suitable for cutting, forming, drilling and machining, grinding.

Alloying elements can strengthen the properties of structural steels. EN 10025 S550QL high strength steel, Alloy structural steel has suitable hardenability. After proper metal heat treatment, the microstructure is uniform sorbite, bainite or very fine pearlite. Therefore, alloy structural steel has higher tensile strength and yield ratio (generally about 0.85), higher toughness and fatigue strength, and lower ductile brittle transition temperature. Alloy structural steel can be used to manufacture machine parts with larger section size.

Raw materials (scrap steel, pig iron and molten iron) → electric furnace (100 tons electric arc furnace smelting) → converter → LF furnace molten steel refining treatment → VD or VOD furnace molten steel vacuum treatment → die casting (various key die casting lines) or continuous casting (large Slab caster) (50 tons of slab electroslag furnace for remelting a steel ingot) → heating (continuous furnace and soaking furnace) → steel plate rolling (4100 and 4200mm rolling mills) → steel plate heat treatment (normalizing and tempering) Quality) →Steel plate cutting inspection→Inspection
