H.E. test results 是指什么报告，电镀螺丝产品评论
Element’s Hydrogen Embrittlement (HE) testing determines the performance of materials in a corrosive environment under the influence of the tensile stress by evaluating the material’s ductility as a result of hydrogen absorption. The tests may be carried out according to ASTM F519 standard for many industries including Energy, Aerospace and Automotive.
Hydrogen embrittlement occurs when metals are subjected to hydrogen uptake during plating processes or as a result of corrosion in the service environment. This causes the metal to lose ductility and toughness and become brittle, resulting in premature failure under static loads.
There are two types of Hydrogen Embrittlement (HE): Internal HE, which occurs when the hydrogen enters metal during forming, coating, plating, cleaning, and finishing operations; and Environmental HE, resulting from hydrogen being absorbed from the environment.
Element performs HE testing for coating and plating processes that can cause hydrogen embrittlement in steels, and on the metals in simulated service environments. Our deep knowledge of corrosion testing and years of experience means that we know the challenges of assessing hydrogen-related damage in many industries.

加拿大电商我们公司老板个人一笔外汇收入15000美金,然后他不知道让老外打到我们公司的帐户里来了,那这笔款怎么入帐呀 ,如果作内销不是要缴税吗?!那不是太冤了,我可不可以当作订金(预收帐款 加拿大电商各位，我问下，台湾用信汇到大陆，大概需要几天的时间？急都急死了，等着付钱 评论 一般新台币和人民币不可能从台湾打过来，其实从美国，或者哪个国家打过来24小时，尽管多出一
