API 5L Gr X46 Kauv Pipe piav qhia
Lub "X46" nyob rau hauv X46 kauv welded yeeb nkab sawv cev rau qib yield zog ntawm cov hlau siv, nrog rau cov nqi tshwj xeeb ntawm kwv yees li 315 MPa. Cov hlau no ua kom muaj zog thaum tseem muaj qee qhov toughness thiab ductility, ua rau cov yeeb nkab tsis tshua muaj kev puas tsuaj rau hauv siab. X46 steel feem ntau yog qis- alloy siab- lub zog steel uas muaj cov khoom xws li manganese, silicon, npib tsib xee, thiab chromium. Qhov sib ntxiv ntawm cov hlau alloy no pab txhim kho kev ua tau zoo ntawm cov yeeb nkab steel, nrog rau kev tiv thaiv corrosion, oxidation tsis kam, thiab weldability.
