    • The steel pipe has a structure composed mainly of ferrite or ferrite plus pearlite or ferrite plus cementite. The steel pipe is characterized by grain size not greater than 3 &mgr;m, preferably not greater than 1 &mgr;m, elongation greater than 20%, tensile strength (TS:MPa) and elongation (E1:%) whose product is greater than 10000, and percent ductile fracture greater than 95%, preferably 100%, measured by Charpy impact test on an actual pipe at −100° C. The structure is characterized by C: 0.005-0.03%, Si: 0.01-3.0%, Mn: 0.01-2.0%, and Al: 0.001-0.10% on a weight basis, and is composed of ferrite or ferrite and a secondary phase, with ferrite grains being not greater than 3 &mgr;m and the secondary phase having an areal ratio not more than 30%. A steel pipe stock having the above-mentioned composition is heated at a temperature of (Ac1+50° C.) to 400° C. and subsequently reduced at a rolling temperature of (Ac1+50° C.) to 400° C. such that the cumulative reduction of diameter is greater than 20%. The reducing is preferably performed such that at least one of rolling passes reduces the diameter by more than 6% per pass. The steel pipe will have high ductility and high strength and will be superior in toughness and stress corrosion cracking resistance, if the content of C, Si, Mn, and other alloying elements is limited low and reducing is performed at the temperature specified above. The resulting steel pipe has good fatigue resistance and is suitable for use as line pipe.
    • 钢管具有主要由铁素体或铁素体加珠光体或铁素体和渗碳体组成的结构。 钢管的特征在于,其粒径不大于3μm,优选不大于1μm,伸长率大于20%,拉伸强度(TS:MPa)和伸长率(E1:%)大于10000, 延性断裂大于95%,优选100%,通过夏比冲击试验在-100℃的实际管上测量。该结构的特征在于C:0.005-0.03%,Si:0.01-3.0%,Mn:0.01-2.0 %,Al:0.001-0.10%,由铁素体或铁素体和二次相组成,铁素体晶粒不大于3μm,第二相的面积比不大于30%。 将具有上述组成的钢管坯料在(Ac1 + 50℃)的温度下加热至400℃,随后在(Ac1 + 50℃)的轧制温度下降低至400℃。 使得直径的累积减小大于20%。 优选地进行还原,使得至少一个轧制通道将直径每次通过减少6%以上。 如果C,Si,Mn和其他合金元素的含量低,并且在上述规定的温度下进行还原,则钢管将具有高延展性和高强度,并且在韧性和耐应力腐蚀开裂性方面优异。 所得钢管具有良好的抗疲劳性能,适用于管线管。
