摘要： A heavy wall and high strength seamless steel pipe having high sour resistance is provided. In particular, a quenching and tempering treatment is conducted to adjust the yield strength to be higher than 450 MPa and adjust the Vickers hardness HV5 that can be measured at an outermost side or an innermost side of the pipe under a 5 kgf load (test load: 49 N) to be 250 HV5 or less.

摘要： In a magnetic recording medium wherein a magnetic coating composition comprising a binder and a magnetic powder is applied to the surface of a substrate, the dispersion of magnetic powder in binder is improved for enhanced physical and electromagnetic properties by using a vinyl chloride/hydroxyl group-containing vinyl monomer/polar group-containing monomer copolymer or a vinyl chloride/vinyl acetate/hydroxyl group-containing vinyl monomer/polar group-containing monomer copolymer having not been subjected to saponification, the polar group-containing monomer preferably containing an epoxy group as an additional polar group. Electromagnetic properties are further improved with a metal magnetic powder having a BET value of up to 60 m.sup.2 /g and a pH value of at least 7.
