马氏体不锈钢材料在油气田开发中的应用

Application of martensitic stainless steel in oil and gas field development

马氏体不锈钢是一种铬不锈钢,在常温下呈马氏体显微组织;通过热处理,可以改变金属内部的显微组织,从而改善工件在强度、硬度、耐磨性等物理性能和力学性能。在耐蚀合金油、套管中,马氏体不锈钢的用量最大,它主要用于以二氧化碳为主的腐蚀环境。

Martensitic stainless steel is a chromium stainless steel with a martensitic microstructure at room temperature;through heat treatment,the internal microstructure of the metal can be changed,thereby improving the physical and mechanical properties of the workpiece such as strength,hardness,wear resistance,etc.. Among the corrosion-resistant alloy oil and casing,martensitic stainless steel is the most widely used,which is mainly used in the corrosion environment dominated by carbon dioxide.
