1. In Mar. 2018, we produced Ni-Hard Cast Iron Blades, delivered to UK.
  2. There are threes sizes of the blade                                                                                                                                                                                                                                                                                                2 Hole Blade                                                                                                                                                                                                                                                                                                                                      3 Hole Blade                                                                                                                                                                                                                                                                                                                             Paddle Blade

5.Nickel hard white cast iron is a kind of white cast iron with excellent wear-resisting property. It is widely used in grinding machine liner, chute liner, blenders wear resistant blade and so on.Nickel Hard white cast iron contains nickel and chromium alloy elements, known internationally as “ni-hard”, China has included  alloy group into its White Iron national standard..The addition of nickel can improve the hardenability, obtain the metal matrix with martensite as the main body, with more austenite residues, and improve the toughness.The addition of chromium prevents the precipitation of graphite and produces high – hardness carbide.Application and grinding machine lining board, chute lining board, mixer wear – resistant blade, etc.
