VDA 238-203 - Testing of the susceptibility of advanced high strength steel sheets to hydrogen induced cracking - Cup test

The cup test is designed to assess the susceptibility of AHSS grades to delayed cracking due to hydrogen induced stress corrosion cracking. Particular consideration is given to production-related influences on the material behavior (for example work hardening by forming, cathodic dip coating) as well as influences from the product life cycle (corrosion). For this test, deep drawn cups are exposed to a corrosive media and the number and type of delayed cracks, if occurring, are evaluated.

The cup-test is a test method for sheet steels for automotive applications, especially cold-formable multi-phase steels with a typical thickness range of 0.7 to 2.5 mm.

杯形试验旨在评估先进高强钢（AHSS）等级对氢致应力腐蚀开裂的敏感性。在试验中，特别关注与生产相关的因素对材料性能的影响，例如成形过程中的工作硬化以及阴极浸镀涂层等，同时亦考虑产品生命周期（腐蚀）的影响。本试验中，深冲杯形件暴露于腐蚀性介质中，并评估延迟开裂的数量和类型，如有发生。杯形试验是针对汽车应用领域的钢板测试方法，尤其是具有典型厚度范围0.7至2.5毫米的冷成形多相钢。本出版物及其他文档现可在我们的新在线商店中查阅。首次订购时，请在新在线商店中重新注册。如遇任何疑问，请通过[e-mail]与我们联系。
