•API standard oilfield stabilizers are manufactured from one solid bar of AISI 4145H modifed steel, usually have 3 blade or 4 blades.Professional heat-treatment process gurantees the mechanical strengths meet the requirments of API SPEC7-1. Hardness of 285-341HB can be assured with 1'' beneath the outer surface and 4 quadrant across the neck OD.

•Replaceable sleeve stabilizer consists of mandrel and sleeve. The function is the same as spiral integral blade stabilizer.
