Abstract
A case-hardened steel pipe which has a hardness of 72 to 80HRB and which can give an end product having a carburized case exhibiting high strength and wear resistance and satisfactorily high fracture resistance under impact load through working followed by carburizing and quenching under relatively mild conditions. The case-hardened steel pipe can be produced by making a pipe from a steel having a composition which contains by mass C: 0.1 to 0.25%, Si: 0.2 to 0.4%, Mn: 0.3 to 0.9%, P: 0.02% or below, S: 0.001 to 0.15%, Cr: 0.5 to 0.9%, Mo: 0.15 to 1%, Al: 0.01 to 0.1%, B: 0.0005 to 0.009%, and N: less than 0.006% with the balance consisting substantially of Fe, normalizing the pipe by soaking at a temperature of 880 to 980°C and then cooling at a cooling rate of 70°C/min or below, subjecting the normalized steel pipe to cold working, and then annealing the cold-worked steel pipe at a temperature of 700 to 820°C. A case-hardened steel pipe which has a hardness of 72 to 80HRB and which can give an end product having a carburized case exhibiting high strength and wear resistance and satisfactorily high fracture resistance under impact load through working followed by carburizing and quenching under relatively mild conditions. The case-hardened steel pipe can be produced by making a pipe from a steel having a composition which contains by mass C: 0.1 to 0.25%, Si: 0.2 to 0.4%, Mn: 0.3 to 0.9%, P: 0.02% or below, S: 0.001 to 0.15%, Cr: 0.5 to 0.9%, Mo: 0.15 to 1%, Al: 0.01 to 0.1%, B: 0.0005 to 0.009%, and N: less than 0.006% with the balance consisting substantially of Fe, normalizing the pipe by soaking at a temperature of 880 to 980°C and then cooling at a cooling rate of 70°C/min or below, subjecting the normalized steel pipe to cold working, and then annealing the cold-worked steel pipe at a temperature of 700 to 820°C. The object is to prevent the adhesion of fluorometholone contained in a suspension-type eye drop preparation onto the surface of a container. The adhesion of fluorometholone contained in a suspension-type eye drop preparation onto the surface of a container can be prevented by adding a polyoxyethylene hydrogenated castor oil or a polyoxyethylene castor oil to the preparation.
