The Lab Research on EH40 High Strength Shipbuilding Steel

Abstract:

Through composition designing, smelting, TMCP and normalizing on EH40 in laboratory, then mechanical properties are detected respectively in tensile and impact test, the results are dawn as follow. The yield strength, tensile strength, reduction of area, percentage elongation and impact toughness of EH40 samples, which are not normalized, reach the national standards. Yield strength and tensile strength of the normalizing samples are lower than the national standards, but the impact toughness decreases greatly. The research on EH40 reaches its goals, but the normalization process needs improvement in this test.
