Grade 8.8 Hex Cap Bolt High Temperature Resistance For Vehicle Wheel Wind Power

High Temperature Resistance Grade 8.8 Dacromet Silver Gray Hex Cap Bolt for Vehicle Wheel, Electric Power, Wind Power

Dacromet bolt refers to the surface of the bolt plated with Dacromet. Dacromet is a new type of anti-corrosion coating with zinc powder, aluminum powder, chromic acid and deionized water as the main components. Compared with the traditional electroplating process, Dacromet is a "green electroplating". Its advantages are as follows:
1. Superior corrosion resistance: The thickness of the Dacromet film layer is only 4-8μm, but its anti-rust effect is more than 7-10 times that of traditional electro-galvanizing, hot-dip galvanizing or paint coating methods. Standard parts and pipe joints treated by Dacromet process did not show red rust after salt spray resistance test for more than 1200h.
2. No hydrogen embrittlement: Dacromet's treatment process determines that Dacromet has no hydrogen embrittlement phenomenon, so Dacromet is very suitable for the coating of stressed parts.
3. High heat resistance: Dacromet can resist high temperature corrosion, and the heat resistance temperature can reach above 300℃.
4. Good adhesion and recoating performance:
5. Good permeability:
6. No pollution and public nuisance:
