What's the resistance against galvanic corrosion for zinc plated camloc parts?
Our zinc plated steel parts (partnumber ends with AGV) have a corrosion resistance that is measured with a salt spray test.
- After 120 hours salt spray – white rust starts
- After 240 hours salt spray – red rust starts (parent material is getting damaged
test 1
Second test: 120 hours value A which means nothing happened ; this means parts can be approved for 120 hours corrosion proof on the salt spray test 168 hours value G3 which is a very light view of corrosion only affected for maximum 10% of the surface of the part 216 hours value G4 which is a very light view of corrosion only affected for maximum 25% of the surface of the part 240 hours this is still the same, and not yet the level of L6 ,so it can be safely said that after 240 hours salt spray test the parts start to rust, so it’s even with a big safety factortest 2
conclusion: AGV is guaranteed 120 hours first white corosion AGV is guaranteed 240 hours first red corrosion (parent material)Tags:
