1.Premium Chromium Liners: Outer Shell: *5# forged steel, tensile strength is σb>**0MPa, yield strength is σs>**0MPa, elongation is δ>*7%, hardness is HRC******0 Inner Sleeve: Hy-chrome forged steel (centrifugal forged). Annealing hardness is HRC≤*0. Quenching hardness is HRC****7.
2.Ceramic linerscombine the strength of a forged steel out shell with the abrasion and corrosion resistance of a ceramic inner sleeve. We provide Zirconia(ZrO3) sleeves as well as Alumina(AL2O3) sleeves of which Zirconia exhibits better impact strength, higher hardness and can be honed to finer surface finishes than alumina.

Ceramic liners are your best choice, extreme longer service life and reliable quality gives you a guarantee.

3.Chromium-plated Liners:We offer chromium-plated liners made from premium forged steel with the core plated by chrome. The chrome-plated liners have hardening characteristics of *8 to *2 Rockwell C hardness. Material is *5# forged steel, tensile strength is larger than **0MPA, elongation is larger than *7%, hardness is HRC******0. The bore is plated by chrome, thickness is 0.*5*0.*8mm, hardness is HRC ****0.
4. Hardened liners offer economy in a liner that is made for normal to mildly corrosive mud conditions. These liners are hardened and heat treated under strict quality control to a minimum of *0 RC hardness and a depth of **5 inches. Each liner is honed to a mirror-like finish for smooth and even wear during the life of the liner and is machined to close tolerances to assure easy installation and long life.
