Nitriding steel - Import export

Nitriding treatment is a chemical heat treatment process in which nitrogen atoms penetrate the surface of the workpiece at a certain temperature and in a certain medium. The products treated with nitriding have excellent wear resistance, fatigue resistance, corrosion resistance and high temperature resistance. The general process of nitriding process :1. Pretreatment: clean, remove oil and dry the metal surface to ensure that the surface is clean and free of impurities. 2. Nitriding treatment: The metal is placed in an atmosphere containing nitrogen and treated at high temperatures to form a nitriding layer on the surface of the metal. 3. Post-treatment: Clean and cool the metal surface after nitriding to remove the residual nitride layer and prevent its oxidation. The nitriding process is of great importance for many industrial fields, such as tool manufacturing and automotive parts manufacturing.

Silicon Nitride Ceramic Balls are widely used on bearings with extreme performance requirements, such as: High-speed bearings, high precision bearings, vacuum bearing, high / low-temperature bearing, non-magnetic bearing, high precision ball screw; it is also used as valve ball, measuring ball for the chemical pump, heat pumps, metering pumps. Its excellent properties including: Good corrosion resistance withstands attacks from harsh chemicals and environments. High-Temperature Hardness is twice that of steel, Silicon nitride ceramic balls retain their strength and hardness up to 1800 degrees F.Lightweight, silicon nitride ceramic balls’ density is 3.20g/cm3 and weighs 45% less than steel which reduces centrifugal force, skidding and wear under high speed and acceleration, so greatly extending the service life. Superior Surface Finish is conducive to improving working speed and reach higher accuracy.
