Abstract： The trialprodction of Shaogang offshore platform plate in grade E36 was introduced. The offshore platform plate with 60 mm thickness in grade E36 was successfully produced through the proper compositional design with niobium,titanium,nickel microalloyed, reasonable rolling and cooling process, and normalizing heat treatment process. The microstructure of tested steel is homogeneous from surface to center, the grade of the grain size is 95, and the strength, ductile and throughthickness characteristics meet the requirements. Shaogang had successfully trialed the offshore platform plate with 60mm thickness in grade E36Z35 under normalizing delivery condition.
