合理选择不锈钢的必备条件

  由于不锈钢类型多,列入标准的牌号多,同时尚有大量广泛使用的非标准牌号,这些牌号性能各异,同时尚有大量广泛使用的非标准牌号,这些牌号性能各异,因此恰如其分地选择适用的不锈钢牌号的难度很大。它涉及到材料学、腐蚀学以及工程学等多种学科的专门知识,除此以外,工程经验是合理选用不锈钢不可缺少的重要条件。

  合理选择不锈钢的必备条件,对不锈钢部件或设备用材的合理选择应必备下述条件和学科知识。

(1)服役条件
  不锈钢部件或设备的服役条件包括腐蚀介质成分、温度、压力、受力状态、预期寿命等, 是选择适用不锈钢的先决条件。充分了解部件的使用条件,是合理选择不锈钢必备的首要条件。

(2)深入了解不锈钢性能和相关数据
  应根据部件或设备的工作条件选择不锈钢材料,选材者应对各类不锈钢性能、限制其使用的环境因素,是否易于购得等知识有较全面的了解,方能有针对性地进行选择。

(3)工程实践经验
  同类服役条件下,不锈钢材料实际使用经验是合理选材的重要依据,应特别予以重视。

(4)模拟试验数据

在许多腐蚀环境下,在没有实际使用经验的条件下,实验室模拟试验数据或现场挂片数据往往是合理选用不锈钢材料的关键数据。
