S550QL1 high strength steel EN 10025-6 specification

S550QL1 steel is a high yield strength structural steel with quenched and tempered, S stands for structural steel, 550 is the yield value, the unit is MPa,  Q is the delivery condition, L1 represents the minimum value specified for impact energy when the temperature is not lower than -60℃. S550QL1 steel grade under the EN 10025-6 specification. The standard stipulates that the nominal thickness of steel is as small as 3mm, and the nominal thickness is ≤150mm. For thicknesses less than 50 mm, the minimum yield strength is 550 Mpa, and for thicknesses between 50 and 100 mm, the minimum yield strength is 530 Mpa.

The necessary technical requirements are required when rolling steel plate S550QL1, including low temperature impact test of quenching and tempering heat treatment performed below 60 degrees Celsius, S550QL1 high yield strength structural steel is delivered in the quenched and tempered state, and S550QL1 steel plate is used for manufacturing High-pressure pipes and various fasteners that work in non-corrosive media and media with a working temperature of less than 250°C and a mixture of nitrogen and hydrogen, as well as higher-grade carburized parts, such as gears, shafts, etc.
