S550Q High Strength Low Alloy Plate

 

‌S550Q high strength low alloy steel plate is a quenched and tempered high strength steel plate, which belongs to special alloy steel and has excellent mechanical properties and durability‌.

 

S550Q low alloy structural steel has a high load-bearing capacity. "Q" means that it has good impact performance at -20℃, and can be reliably used in low temperature conditions, such as construction in cold areas, outdoor engineering machinery and other fields‌.

 

S550Q high strength steel plate is widely used in many fields such as construction, bridges, vehicles, mechanical equipment, port machinery and lifting hydraulic equipment manufacturing due to its high strength, high toughness, corrosion resistance and good processability.

 

GNEE is a supplier of alloy steel plates with 17 years of production experience. The products we provide can be customized in size and various processing services according to your final needs. In addition, we can also provide S355J2 low alloy steel, S690QL1 high yield strength steel and A709Gr50 low-alloy high-strength structural steel plate, etc.

Nominal thickness =< 50(mm) CEV max = 0.65 Nominal thickness from 50 to 100 (mm) CEV max = 0.77 Depending on the thickness of the product and the manufacturing conditions, the manufacturer may add to the steel one or several alloying elements up to the maximum values given in order to obtain the specified properties Nb, Ti, V, Zr: There shall be at least 0.015% of a grain-refining element present. AL is also one of these elements. The minimum content of 0.015% applies to soluble aluminium, this value is regarded as attained if the total aluminium content is at least 0.018%; in case of dispute the soluble aluminium content shall be determined
