Special Design for Boron Carbide Nanopowder - Chromium Nitride Powder Nitrided Metal Chromium Powder CrN – Huarui Detail:

Product Description

Chromium nitride powder has the characteristics of small particle size, uniformity and high surface activity; it is stable to water, acid and alkali. It has good adhesion and good corrosion resistance and oxidation resistance. At the same time, due to its good physical and mechanical properties, it is an antiferromagnetic material in nitrides.

The low carbon ferrochromium is nitrided at 1150°C in a vacuum heating furnace to obtain crude ferrochromium nitride, which is then treated with sulfuric acid to remove iron impurities. After filtration, washing and drying, chromium nitride is obtained. It can also be obtained by the reaction of ammonia and chromium halide.

Application

1. Steelmaking alloy additives;

2. Cemented carbide, powder metallurgy;

3. Used as a wear-resistant coating.
Adding chromium nitride powder to mechanical parts and dies can enhance their lubricity and wear resistance. Higher surface hardness, lower friction coefficient and lower residual stress make it suitable for wear-resistant, metal-to-metal friction applications.

Quality control system

quality control

Huarui has strict quality management system. We test our products first after we finish our production, and we test again before every delivery, even sample. And if you need, we would like to accept third party to test. Of course if you like, we could provide sample to you to test.

Our product quality is guaranteed by Sichuan Metallurgical Institute and Guangzhou Institute of Metal Research. The long term cooperation with them can save a lot of testing time for customers.
