A: Look at the road outside. The hard stone pieces are held in place by a soft tar matrix. It lasts for years. Our CrC (with MaxCS™) works on the same principal. Chromium at 24% is “alloyed” to Carbon at 4% forming Carbides (CrC). These have a hardness of 1800 V.P.N. (very hard!) and are held in place by an iron (steel) matrix (”glue”).
Now you have our LONG-LIFE CrC liners!
Chromium Carbide (CrC) alloys have wonderful properties:
Rio-Carb exploits this to the full with its MaxCS™ development,
Rio-Carb liners have a combination of abrasion resistant Chromium Carbide alloy, fused onto a ductile and weldable mild steel base plate,
The CrC alloy consists of CrC particles suspended in a hard and stable matrix,
The carbide hardness is approx 1800 VPN,
The matrix is 450 Brinell, giving a macro-hardness of 56-58 Rc,
The relief checks are desirable and indicate there is no cracking away of the hard layer from the mild steel base.
