- 点蚀 | 不锈钢点蚀当量（PREN）公式来源 - 知乎
PREN的经典公式首次在 1973年 由 英国钢铁公司 （BSC）的研究者 John Charles和Sidney K Cobden 提出，发表于论文： 《British Corrosion Journal》 （1973, Vol 8, No 2），该公式由欧洲多个科学家与研究机构在实际腐蚀测试基础上归纳总结形成。
- Pitting resistance equivalent number - Wikipedia
Pitting resistance equivalent number (PREN) is a predictive measurement of a stainless steel's resistance to localized pitting corrosion based on its chemical composition

抗点蚀当量数（Pitting Resistance Equivalent Number，简称PREN）是一种用于评估和比较不同不锈钢合金及其它材料抗点蚀腐蚀能力的指标。 PREN不是一个绝对的数值，但它提供了一种简单的方法来估计合金在特定腐蚀环境下的性能。 什么是点蚀腐蚀？
- Pitting Resistance Equivalent Number (PREN) - Corrosionpedia
The pitting resistance equivalent number (PREN) is a theoretical way of comparing the pitting corrosion resistance of various types of stainless steels based on the chemical compositions of an alloy
- Pitting Resistance Equivalent - an overview - ScienceDirect
Pitting resistance equivalent number (PREN) is such a method and it is widely used as a means of comparing the relative corrosion resistance of different steels PREN is a theoretical way of comparing the pitting corrosion resistance of stainless steels, based only on their chemical compositions
- 什么是「耐点蚀当量」？ - 搜狐
耐点蚀当量，Pitting Resistance Equivalent Number，简称“ PREN ”或“PRE值”。 PREN是定量评定与标示不锈钢综合耐腐蚀性能的重要参数，准确一点说用来评价不锈钢在氯化物环境中抵抗点蚀的能力。 通常认为，当PREN超过32时，可耐海水腐蚀。
