  材料特性 Material Characteristics

  S32750是一種鐵素體-奧氏體（雙相）不銹鋼，它綜合了許多鐵素體鋼和奧氏體鋼最有益的性能，由于該鋼鉻和鉬的含量都很高，因此具有極好的抗點腐蝕、縫隙腐蝕和均勻腐蝕的能力。雙相顯微組織保證了該鋼具有很高的抗應(yīng)力腐蝕破裂的能力，而且機械強度也很高。

  機械特性:S32750具有很高的耐壓強度、沖擊強度及較低的熱膨脹系數(shù)和較高的導(dǎo)熱性。這些特性適用于很多結(jié)構(gòu)零件及機械部件。

  S32750 is a ferritic-austenitic (duplex) stainless steel. It combines the most beneficial properties of many ferritic and austenitic steels. Because of its high chromium and molybdenum content, it has extremely high Good resistance to pitting, crevice and uniform corrosion. The dual-phase microstructure ensures that the steel has high resistance to stress corrosion cracking and high mechanical strength.

  Mechanical characteristics: S32750 has high compressive strength, impact strength, low thermal expansion coefficient and high thermal conductivity. These characteristics apply to many structural parts and mechanical parts.
