20G seamless steel yeeb nkab yog ib hom yeeb nkab hlau seamless uas siv ntau. Lub npe "20G" sawv cev rau cov khoom siv ntawm cov yeeb nkab hlau, thiab "seamless" sawv cev rau cov txheej txheem tsim khoom. Cov hlau no feem ntau yog ua los ntawm cov hlau carbon, hlau alloy, thiab lwm yam, thiab muaj cov khoom siv kho tshuab zoo thiab weldability. Cov yam ntxwv tseem ceeb ntawm 20G seamless steel yeeb nkab yog qhov kub thiab txias, tiv taus corrosion, lub zog compressive siab, thiab lwm yam. Yog li ntawd, nws yog siv dav hauv roj av, roj av, kev lag luam tshuaj lom neeg, hluav taws xob, kev tsim kho thiab lwm yam teb.
