材料特性 Material Characteristics
主要用于化学加工、石油化工和海底设备。它具有较强的抗氯化物腐蚀能力,较高的导热性和较低的热膨胀系数。
较高的铬、钼及氮含量使它具有很高的抗斑蚀、裂缝腐蚀及一般腐蚀的能力。
Mainly used in chemical processing, oil processing and submarine equipment. It has strong resistance to chloride corrosion, high thermal conductivity and low coefficient of thermal expansion.
The high chromium, molybdenum and nitrogen levels makes it highly resistant to pitting, crevice corrosion and general corrosion.
