  材料特性 Material Characteristics

  主要用于化學(xué)加工、石油化工和海底設(shè)備。它具有較強的抗氯化物腐蝕能力，較高的導(dǎo)熱性和較低的熱膨脹系數(shù)。

  較高的鉻、鉬及氮含量使它具有很高的抗斑蝕、裂縫腐蝕及一般腐蝕的能力。

  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.
