DIN933 ISO4017 EN24017 Hexagon Head Bolts - Full Thread Dacromet Carbon Steel/Alloy Steel Class 8.8 10.9
Characteristics:
High Corrosion Resistance: The Dacromet coating offers excellent corrosion resistance, providing up to 7-10 times more protection than traditional electrogalvanizing.
Good Heat Resistance: The coating maintains its integrity and performance even at temperatures up to 250°C, surpassing the heat resistance of traditional zinc coatings.
No Hydrogen Brittleness: The Dacromet process does not involve the production of hydrogen embrittlement, which makes it suitable for high-strength steel components.
High Penetration: The coating penetrates into fine pores of the base metal, creating a dense protective film.
Excellent Weatherability: The coating maintains its performance under various environmental conditions.
Strong Adhesion: The Dacromet coating adheres tightly to the base metal, preventing peeling or cracking.
Environmentally Friendly: The process of applying the Dacromet coating is environmentally safe.
Advantages:
Strong Binding Force: The Dacromet coating readily bonds to other metals, enhancing the overall strength and reliability of the bolted joint.
Excellent Corrosion Protection: The coating significantly extends the service life of bolts by protecting them from corrosion.
High Heat Resistance: Bolts with Dacromet coating can be used in high-temperature environments.
Aesthetic Appeal: The bolts have a smooth, uniform finish that adds to their visual appeal.
Applications:
DIN 933 bolts with Dacromet coating find applications in various industries requiring high corrosion and heat resistance, such as:
