In cases of material having lowductility, such as severely cold worked material, a 180° bendmay prove impractical. Users shall inform those conducting thePractice E test when the material is in the low ductility highlystressed condition, such as highly cold worked material.Determine the maximum ...
Oxalic Acid Etch Test is used for acceptance of wrought or cast austenitic stainless steel material but not for rejection of e of A262Practice A as a stand-alone test may reject material that the applicable hot acid test would ?nd acceptable;such use is outside the scope of this test is...
第一步也是最快的一步是ASTM A262 Practice A，一种在草酸中的快速（即日）筛选方法，以确定对晶间腐蚀的敏感性。经过A262 A后的结构分类分析将确定该材料是否可以接受或是否需要进行其他晶间腐蚀测试。如果不确定，请与我们联系以获取帮助。根据您的材料，应用和要求，其他4种方法提供了特定的重点。在日常应用中...
- Practice E - 铜-硫酸铜-硫酸测试:用于检测奥氏体不锈钢晶间腐蚀敏感性。该测试基于弯曲试样的目视检查,将样品在硫酸铜、铜混合物中煮沸 15 小时,然后在相等直径处弯曲 180,通过低放大倍率检查弯曲的样品,观察是否有裂纹或裂缝出现,以确定是否发生晶间腐蚀。 - Practice F - 铜-硫酸铜-50%硫酸测试:用于...
