Multiple service acid has very little corrosive effect and does not cause hydrogen embrittlement.
多功能酸的腐蚀性极小，而且不会引起氢脆。
2
The reason for hydrogen embrittlement fracture is incomplete removal of hydrogen after acid-washing or electroplating.
是在酸洗电镀后除氢不及时或不彻底导致氢脆断裂。
3
Rust against heat-treated water-embrittlement resistance to further develop the ultra-thin thickness of chromic acid-high corrosion resistance of the surface treatment technology.
