High yield strength steel plate S550QL1 under EN 10025-6 owned the minimum yield strength at 550 Mpa and tensile strength within 640-820 Mpa.The necessary technical requirement when rolling steel plate S550QL1 contains quenching and tempering heat treatment,low temperature impacting test under minus 60 centigrade.The additional technical has Ultrasonic examination.

 

Mechnical property for S550QL1 High strength steel:

 

Chemical composition % of the Product analysis of steel grade S550QL1 (1.8986)

Nominal thickness = 50(mm) CEV max = 0.65

Nominal thickness from 50 to 100 (mm) CEV max = 0.77

Nominal thickness from 100 to 150 (mm) CEV max = 0.83
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

There shall be at least 0,010% of a grain-refining element present. Aluminium is also one of these elements. The minimum content of 0,010 % applies to soluble aluminium, this value is regarded as attained if the total aluminium content is at least 0,013 %; in case of dispute the soluble aluminium content shall be determined.

Specification:Thickness 8mm-300mm, Width: 1500-4020mm, Length: 3000-27000mm
