S550Q Steel Plate Introduces the performance of S550Q steel plate

S550Q is a quenched and tempered high-strength steel plate, which is a special alloy steel, and the impact performance is specified when the temperature is not less than -20 degrees; The impact performance specified at a temperature not lower than -40 degrees is recorded as: L; The impact performance specified at a temperature not lower than -70 degrees is denoted as: L1.
2. S550Q steel plate implementation standard: EN10025-6:2014
3. S550Q steel plate delivery status:
(1) S550Q steel plate stipulates that the product needs to be quenched and tempered (quenching + tempering) (2)
S550Q steel grade must be completely calmed, and the steel should have fine grain structure and sufficient nitrogen fixing elements
(3) The steel plate shall be delivered
by shearing or flame cutting4, S550Q steel plate size, shape, weight and allowable deviation S550Q steel plate size, shape, weight and allowable deviation: The size, shape and allowable deviation
of the steel plate shall comply with the provisions of 2.2 in 2004 in EN10025-1.
