HOLLOW-SHAPED STABILIZER AND MANUFACTURE THEREOF

摘要

PROBLEM TO BE SOLVED: To provide a hollow-shaped stabilizer and a method of its manufacture capable of use under a condition of higher preset stress by reinforcing an inner surface of the hollow-shaped stabilizer. SOLUTION: This hollow-shaped stabilizer formed by a steel pipe having a cemented steel layer in an inner surface is obtained by applying an applying type carburizing composition formed by compounding a carburizing compound in water paint and an inactive carburizing promoting agent relating to the water paint to the inner surface of the steel pipe, forming a film by drying, mold working the steel pipe formed with the film, forming the cemented steel layer by heating for a sufficient time at a sufficient temperature for forming the cemented steel layer, and then performing hardening treatment by quenching.
