标准名称:Standard Guide for Examination and Evaluation of Pitting Corrosion
标准编号:ASTM G46–94
实施日期: 2005-05-01
标准概述:This guide covers the selection of procedures that can be used in the identi?cation and examination of pits and in the evaluation of pitting corrosion to determine the extent of its effect.This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
标准名称:Standard Test Method for Electrochemical Critical Pitting Temperature Testing of Stainless Steels
标准编号:ASTM G150–99
实施日期: 1999-01-10
标准概述:This test method covers a procedure for the evaluation of the resistance of stainless steel and related alloys to pitting corrosion based on the concept of the determination of a potential independent critical pitting temperature (CPT)。This test methods applies to wrought and cast products including but not restricted to plate, sheet, tubing, bar, forgings, and welds.The standard parameters recommended in this test method are suitable for characterizing the CPT of austenitic stainless steels and other related alloys with a corrosion resistance ranging from that corresponding to solution annealed UNS S31600 (Type 316 stainless steel) to solution annealed UNS S31254 (6 % Mo stainless steel)。
标准名称:不锈钢三氯化铁点腐蚀试验方法
标准编号:GB/T 17897-1999
发布日期:1999-01-01
实施日期: 2000-08-01
标准概述:本标准规定了不锈钢三氯化铁点腐蚀试验方法的试样的制备、试验溶液、试验仪器和设备、试验条件和步骤、试验结果和试验报告。本标准适用于评价不锈钢在6%三氯化铁溶液中的耐点蚀性能。注:本试验方法所用的试验溶液,氧化性强,酸性强,氯离子含量较高,因此腐蚀性强。当材料在试验溶液中发生金属间化合物的溶解或有析出物时,往往会加速腐蚀。特别是合金素钛往往会加剧腐蚀。因此,用本试验方法来比较不同材料的耐点蚀性能,或者把实验数据与实际环境进行比较时,要注意本试验溶液的特性。
