材料特性 Material Characteristics
S32750是一种铁素体-奥氏体(双相)不锈钢,它综合了许多铁素体钢和奥氏体钢最有益的性能,由于该钢铬和钼的含量都很高,因此具有极好的抗点腐蚀、缝隙腐蚀和均匀腐蚀的能力。双相显微组织保证了该钢具有很高的抗应力腐蚀破裂的能力,而且机械强度也很高。
机械特性:S32750具有很高的耐压强度、冲击强度及较低的热膨胀系数和较高的导热性。这些特性适用于很多结构零件及机械部件。
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.
