Processing of D36 high-strength ship plate steel

The main specification and process route during production and exploitation of D36 high-strength ship plate steel in Xunyu Iron and Steel Co., Ltd. were introduced. During the exploitation of D36 high-strength ship steel, thickness deviation changing and bad plate weldability were risen by less functional parameters of the rolling mill. The over-all properties and weldability of the D36 plate were preferably solved and improved by the adjustment of depressed allocation, the translation of product objective thickness and control range, and micro-Ti treatment.
