"API 5L" yog cov yeeb nkab steel yeeb nkab qauv tsim los ntawm American Petroleum Institute. Nws teev cov kev cai rau kev tsim khoom, kev sim, thiab kev lees txais ntawm cov kav dej steel kav; "L485" thiab "X70" sawv cev rau qib yield zog ntawm cov yeeb nkab steel, uas yog, cov yeeb nkab steel yog raug rau qhov siab tshaj plaws kev ntxhov siab nws tuaj yeem tiv taus thaum sab nraud quab yuam yog 485MPa lossis 70ksi.
L485 kabmuaj cov cuab yeej zoo heev, suav nrog lub zog siab, siab toughness thiab zoo heev weldability. Nws lub zog tensile feem ntau yog siab tshaj 570MPa, uas tuaj yeem ua tau raws li cov kev xav tau ntawm kev thauj mus los ntawm kev kub siab thiab cov kua dej loj.
Tsis tas li ntawd, seamless carbon steel yeeb nkab L485 kuj muaj qhov kub thiab txias toughness thiab hydrogen-induced cracking (HIC) tsis kam, thiab tuaj yeem tswj kev ua haujlwm ruaj khov hauv ib puag ncig huab cua.
