Nuclear fastener
The materials involved in the nuclear power field mainly include carbon steel, stainless steel and special alloys. Our company mainly provides stainless steel and special alloys. For such products with higher safety levels, our company uses all imported products from Germany, Britain, France and the United States, and the manufacturing plants with nuclear power qualifications in relevant countries. In terms of fasteners for nuclear power pressure-bearing equipment, our company mainly provides nuclear power three-level and non-nuclear-level fasteners, and implements the raw material specifications of the American ASME system, the French RCC-M system, and the German KTA system. The grades of nuclear power materials involved in our company are as follows:
