Seen from the above table, the S690QL1 performance is stable, 1/4 plate thickness performance all meets standard requirements, and the uniformity of the thickness direction performance is good, the plate thickness of 1/2 performance up to the standard requirements, especially below 60 degree of the 1/4 plate thickness and the 1/2 plate thickness impact over 80J, having been among the domestic first-class.
