Abstract:
(EN)
This metal tube (1) has a circular cross section having an outer diameter D, and the length thereof is 6D or more. The metal tube (1) comprises a high-strength portion (1A) and a low-strength portion (1B). The high-strength portion (1A) is disposed around the circumstance of the metal tube (1) in a range of (2/3)D-3D of the longitudinal dimension of the metal tube (1). The yield strength of the high-strength portion (1A) is 500 Mpa (tensile strength: 980 Mpa) or more. The low-strength portion (1B) is disposed around the circumstance of the metal tube (1) on both sides of the high-strength portion (1A) in the metal-tube longitudinal direction. The yield strength of the low-strength portion (1B) is 60% to 85% of the high-strength portion (1A).
(FR)
L'invention concerne un tube métallique (1), lequel tube a une section transversale circulaire ayant un diamètre externe D, et sa longueur étant de 6D ou plus. Le tube métallique (1) comprend une partie de résistance élevée (1A) et une partie de faible résistance (1B). La partie de résistance élevée (1A) est disposée autour de la périphérie du tube métallique (1) dans une plage de (2/3)D à 3D de la dimension longitudinale du tube métallique (1). La limite d'élasticité de la partie de résistance élevée (1A) est de 500 Mpa (résistance à la traction : 980 Mpa) ou plus. La partie de faible résistance (1B) est disposée autour de la périphérie du tube métallique (1) des deux côtés de la partie de résistance élevée (1A) dans la direction longitudinale du tube métallique. La limite d'élasticité de la partie de faible résistance (1B) est de 60 % à 85 % de celle de la partie de résistance élevée (1A).
(JA)
金属管(1)は、外径Dの円形断面を有し、長さが6D以上である。金属管(1)は、高強度部(1A)と、低強度部(1B)を備える。高強度部(1A)は、金属管長手方向の寸法(2/3)D以上、3D以下の部分に、金属管(1)の全周にわたって配置される。高強度部(1A)の降伏強度は、500Mpa(引張強度なら980MPa)以上である。低強度部(1B)は、高強度部(1A)の金属管長手方向両側に金属管(1)の全周にわたって配置される。低強度部(1B)の降伏強度は、高強度部(1A)の60~85%である。
