Ib qho ntawm cov yam ntxwv tseem ceeb ntawm cov yeeb nkab steel yog nws lub zog siab. Nws tuaj yeem tiv taus lub zog sab hauv uas tsim los ntawm cov kua xa tawm, nrog rau cov quab yuam sab nraud xws li av loads thiab seismic kev ua ub no. Lub zog no yog ua tiav los ntawm cov txheej txheem metallurgical siab heev thiab cov ntsiab lus alloying.
Toughness yog lwm yam khoom tseem ceeb ntawm pipeline steel. Nws ua rau cov khoom siv tiv thaiv kev tawg thiab tawg tsis ua haujlwm, txawm tias nyob rau hauv ib puag ncig hnyav thiab kub heev. Qhov no yog qhov tseem ceeb rau kev tswj xyuas kev ncaj ncees ntawm cov kav dej thiab tiv thaiv kev puas tsuaj loj.
