Product Details

Hydrogen embrittlement risk:

1, Under normal circumstances, products with hardness >32HRC have the risk of hydrogen embrittlement. Therefore, all products of grade 10.9 or higher (including grade 10.9) and products subjected to carburization heat treatment (self-tapping screws) will be exposed to hydrogen embrittlement.

2, Hydrogen embrittlement means that when the product is electroplated, H+ enters the inside of the metal to form bubbles, which causes the screw to be on the spot when it is used, but delayed fracture occurs within 24 hours.

3,  the product with hydrogen embrittlement risk within 4 hours after plating, need to be

sent to the hydrogen furnace, stored at 200 degrees Celsius for about 8 hours; this is called dehydrogenation.

4, hydrogen embrittlement treatment can greatly reduce the risk of hydrogen embrittlement, but can not be completely avoided, so in the case of the need to ensure 100% no risk of hydrogen embrittlement, the use of electroplating products is strictly prohibited; and the use of Dacromet, sandblasting and other surface treatment processes .
