API 5L tus qauv muaj qhov xav tau meej rau kev xa cov kav hlau. Thaum xa cov yeeb nkab steel, ua tiav kev tshuaj xyuas thiab cov ntawv xeem yuav tsum tau muab thiab lawv yuav tsum tau ntim raws li cov qauv ntim tau teev tseg hauv daim ntawv cog lus. Tsis tas li ntawd, nws tseem yuav tsum tau kos tus lej ntau lawm, kev qhia tshwj xeeb, qib thiab cov ntaub ntawv tsim khoom ntawm cov yeeb nkab steel.

Raws li lub xeev dov (AR): Tom qab kev npaj vuam, cov yeeb nkab tsis tas yuav muaj kev kho cua sov tom qab thaum nws xa tuaj.
Normalized (N): Normalizing muaj cua sov cov yeeb nkab mus rau qhov kub thiab txias thaum lub sijhawm hloov pauv.
quenching thiab tempering (Q&T): Qhov no suav nrog cua sov cov yeeb nkab mus rau qhov kub siab tshaj qhov txuas ntxiv thiab tom qab ntawd quenching hauv qhov nruab nrab tsim nyog (xws li dej los yog roj) kom ruaj khov.
Thermomechanical controlled rolling (TMCR): TMCR muaj kev tswj dov ntawm qhov kub siab tom qab ua kom txias txias.
Normalizing thiab tempering (N&T): Qhov no ua ke cov ntaub ntawv ntawm normalizing thiab kev kho mob los kho cov qauv nplej thiab txhim kho cov khoom siv ntawm cov yeeb nkab.
quenched thiab Tempered nrog los ntawm-Thickness Test (Q&T nrog TT): Sib npaug rau qhov quenched thiab tempered mob, tab sis yuav tsum tau ntxiv los ntawm-thickness kuaj kom paub meej cov khoom sib xws thoob plaws cov yeeb nkab thickness.
