YannacopoulosHigh strength steel - FlinkenbergProcessing and welding is easy. N-A-XTRA® 700 is the most common quenched and tempered structural steel. It combines a high yield strength of at least 700 MPa with outstanding toughness even at temperatures down to -60 °c. Depending on the type of stress involved, using N-A-XTRA® 700 instead of S355 allows a 50 % reduction in plate thickness.Estimated Reading Time: 5 minsHonorary Professor Robert J.
