Cov yeeb nkab hlau yog ib hom yeeb nkab hlau tsis muaj seamless, muab faib ua cov yeeb nkab hlau tsis muaj seamless thiab cov yeeb nkab hlau uas tiv taus cua sov siab. Feem ntau txawv ntawm cov qauv tsim khoom thiab kev lag luam ntawm cov yeeb nkab hlau, cov yeeb nkab hlau uas tau annealed thiab tempered hloov cov khoom siv kho tshuab. Ua tau raws li cov xwm txheej ua tiav. Nws qhov kev ua tau zoo dua li cov yeeb nkab hlau tsis muaj seamless, cov tshuaj lom neeg muaj ntau Cr, yog li nws muaj kev tiv taus kub siab, tiv taus kub qis thiab tiv taus corrosion. Cov yeeb nkab hlau carbon tsis muaj seamless tsis muaj alloy lossis me me ntawm alloy. Cov yeeb nkab hlau yog siv dav hauv roj av, aerospace, tshuaj lom neeg, hluav taws xob, boiler, tub rog thiab lwm yam lag luam, vim tias cov khoom siv kho tshuab ntawm cov yeeb nkab hlau yog hloov pauv, yooj yim kho.

Cov yeeb nkab hlau alloy feem ntau yog siv rau hauv cov chaw tsim hluav taws xob, chaw tsim hluav taws xob nuclear, lub boiler siab, lub tshuab cua sov kub siab, lub tshuab cua sov rov ua dua thiab lwm yam yeeb nkab siab thiab kub siab thiab cov khoom siv. Nws yog ua los ntawm cov hlau carbon zoo, cov hlau alloy thiab cov hlau stainless tiv taus kub los ntawm kev dov kub (extrusion, expansion) lossis dov txias (kos duab).
