Looking for Cost Savings and Corrosion Resistance? We continually strive to meet customers’ needs. Melonite TM Process offers a significant cost savings and alternative option to Stainless Steel. Melonite Process available in the complete ATRA-FLEX® Coupling Line.
• Enhanced corrosion resistance
• Lower coefficient of friction • Enhanced surface lubricity • Improved running wear performance • Increased surface hardness
This process has been proven in the field to prevent corrosion caused from applications in wet or chemical environments as well as wear and fretting due to misalignment and vibration . It penetrates the carbon steel and increases the hardness up to a RC of 57.6 This is not a coating and will not chip or wear off.
