补充资料:不锈钢的物理性能、力学性能和耐热性能
不锈钢的物理性能


不锈钢和碳钢的物理性能数据对比,碳钢的密度略高于铁素体和马氏体型不锈钢,而略低于奥氏体型不锈钢;电阻率按碳钢、铁素体型、马氏体型和奥氏体型不锈钢排序递增;线膨胀系数大小的排序也类似,奥氏体型不锈钢最高而碳钢最小;碳钢、铁素体型和马氏体型不锈钢有磁性,奥氏体型不锈钢无磁性,但其冷加工硬化生成成氏体相变时将会产生磁性,可用热处理方法来消除这种马氏体组织而恢复其无磁性。

奥氏体型不锈钢与碳钢相比,具有下列特点:

1)高的电阴率,约为碳钢的5倍。

2)大的线膨胀系数,比碳钢大40%,并随着温度的升高,线膨胀系数的数值也相应地提高。

3)低的热导率,约为碳钢的1/3。

不锈钢的力学性

不论不锈钢板还是耐热钢板,奥氏体型的钢板的综合性能最好,既有足够的强度,又有极好的塑性同时硬度也不高,这也是它们被广泛采用的原因之一。奥氏体型不锈钢同绝大多数的其它金属材料相似,其抗拉强度、屈服强度和硬度,随着温度的降低而提高;塑性则随着温度降低而减小。其抗拉强度在温度15~80°C范围内增长是较为均匀的。更重要的是:随着温度的降低,其冲击韧度减少缓慢,并不存在脆性转变温度。所以不锈钢在低温时能保持足够的塑性和韧性。

不锈钢的耐热性能

耐热性能是指高温下,既有抗氧化或耐气体介质腐蚀的性能即热稳定性,同时在高温时双有足够的强度即热强性。
