Bimetal Liners
The b-metal liner is composed of two layers and fixed tightly. The outer sleeve is forged steel with abrasion resistance, it adapts the technology of centrigugal forging;  the inner sleeve is high chromium iron with wear&corrosion resistance, after heat treatment, the hardness of it can reach to a lever of 62 RC.
The bimetal liners produced by us strictly control the tolerance, assure the easy installation, inner sleeve is highly polished with abrasion&corrosive resistance, can used in various bad working environment with longer service life. 
Liner Outer Sleeve: 45#forged steel, tensile strength is σb>610MPa, yield strength is σs>450MPa, ,elongation hardness is §>17%,hardness is HRC180-200
Liner Inner Sleeve: high chromium cast iron (centrifugal forged). Annealing hardness is HRC≤40. Quenching hardness is HRC59-67
Chemical Composition:C 2.8%-3.1%  Cr 26%-28%  Si 0.6%-0.9%  Mn 0.5%-1% Mo 0.5%-0.8% S , P <0.05%;

Ceramic Liners
The ceramic liner is composed of two layers and fixed tightly. The outer sleeve is forged steel with abrasion resistance, the inner sleeve is ceramic.
We provide Zirconia(ZrO3) Sleeves as well as Alumina(Al2O3) sleeves., of which Ziconia exhibits better impact strength, higher hardness and be honed to finer surface finishes than alumina.Our ceramic liners are proved to serve for 4000 hours or so.

1. Using time more than 4000 hours
