摘要： The present invention provides a stainless steel having superior corrosion resistance, antibacterial properties, and durability, the antibacterial properties being maintained after surface treatments commonly performed including, for example, polishing. In particular, the stainless steel contains not less than 10 percent by weight of chromium, 0.001 to 0.30 percent by weight of silver, or further contains 0.001 to 1.0 percent by weight of vanadium. In addition, not less than 0.0005 weight percent of a silver oxide, the amount thereof being not more than 1.1 times that of the silver, is dispersed in the stainless steel. In order to homogeneously disperse the silver oxide in the stainless steel, when continuous casting of molten steel is performed, the casting rate for the continuous casting is preferably 0.8 to 1.6 m/min. A method for manufacturing the stainless steel is also disclosed.

摘要： The method of producing steel pipe material for an oil well is characterized in that, as for the chemical composition of steel, B contained steel is adopted avoiding the addition of Ti which increases the values of non-metallic inclusions to decrease machinability, the value of N is limited to not more than 0.003% to be decreased in content of nitrides, coarse crystal grains due to the decreased content of N are prevented through austenizing of steel under rapid heating, so that such a steel pipe material for an oil well can be obtained that which has resistance to sulfide stress corrosion in addition to satisfactory strength and machinability.
