Dacromet is the leading inorganic coating specified by automotive companies worldwide and is a proven coating system in many industries. A water-based, VOC compliant coating, dacromet is comprised mainly of overlapping zinc and aluminum flake in an inorganic binder.
Four-Way Corrosion Protection
Barrier Protection: Overlapping zinc and aluminum flakes provide an excellent barrier between the steel substrate and the corrosive media
Galvanic Action: Zinc corrodes to protect steel
Passivation: Metal oxides slow down the corrosion reaction of zinc and steel to provide 3 times greater corrosion protection than pure zinc
Self-Repairing: Zinc oxides and carbonates migrate to the damaged area of the coating to actively repair the coating and restore barrier protection

Heat treating makes the trailer hub bolt high tensile to be Grade 10.9/12.9. Heat treating is a group of industrial and metalworking processes used to alter the physical, and sometimes chemical, properties of a material. The most common application is metallurgical. Heat treatments are also used in the manufacture of many other materials, such as glass. Heat treatment involves the use of heating or chilling, normally to extreme temperatures, to achieve the desired result such as hardening or softening of a material.
