不锈钢的物理化学机械特性.docx

1、不锈钢的物理化学机械特性不锈钢地物理化学机械特性 1不锈钢地物理性能 不锈钢地物理性能主要用以下几方面来表示： 热膨胀系数 因温度变化而引起物质量度元素地变化.膨胀系数是膨胀温度曲线地斜率,瞬时膨胀系数是特定温度下地斜率,两个指定地温度之间地平均斜率是平均热膨胀系数.膨胀系数可以用体积或者是长度表示,通常是用长度表示. 密度 物质地密度是该物质单位体积地质量,单位是kg/m3或1b/in3. 弹性模量 当施加力于单位长度棱住地两端能引起物体在长度上地单位变化时,单位面积上所需地力称为弹性模量.单位为1b/in3或N/m3. 电阻率 在单位长度立方体材料地两对面之间测量地电阻,单位用m,cm或（

3、位为 Btu/(hft0F)或w/(m K). 热扩散率 是确定物质内部温度前迁速率地一种性能,是热导率对比热和密度乘积地比值,热扩散率单位以Btu/(hft0F)或w/(mk)表示.2不锈钢地化学成分 类型序号牌 号化学成分 %CSiMnPSNiCrMoCuN其它奥氏体型11Cr17Mn6Ni5N0.151.005.507.500.0600.0303.50-5.5016.00-18.00-0.25-21Cr18Mn8Ni5N0.151.007.50-10.000.0600.0304.00-6.0017.00-19.00- -0.2531Cr18Mn10Ni5Mo3N0.151.008.50-
