Dacromet surface metallurgy oil how to do?
If after the sinter process exists basically do not use anti-rust oil, because there is blasting, degreasing and after heat treatment is too much trouble. Mesh belt furnace heat treatment after cleaning no need to use ether or trichlorethylene soak more than 24 hours in order to reduce half of the oil, box-type heat treatment can vacuum cleaning, tempering oil is only about 1%, does not affect Dacromet.
