CCS E690 steel plate delivery status: according to the user's requirements, it can be delivered in hot rolling, normalizing, tempering, normalizing and tempering, quenching and tempering, TMCP and other different states.
Z-direction properties of CCS E690 steel plate:Z15, Z25, Z35.
CCS E690 steel plate is mostly used in the construction of offshore platform. It requires not only high strength, good low temperature impact toughness at - 40 ℃, lamellar tear resistance index (Z-direction performance reaches 35%), but also excellent welding performance.
The welding performance of CCS E690 steel plate is usually reflected in the performance of welded joint. Welding heat affected zone (HAZ) is the zone near the weld of CCS E690 steel plate. It experiences different thermal cycles and different degrees of grain growth at different distances from the weld.
