Nyob rau hauv cov nqe lus ntawm cov khoom tsim, low-temperature alloy kav feem ntau yog ua los ntawm cov uas tsis muaj cov pa roj carbon steel los yog tsawg-alloy steel thiab tau txais kev kho kom haum alloying los txhim kho lawv cov toughness, lub zog thiab corrosion kuj nyob rau hauv qis-kub ib puag ncig.
Piv nrog rau cov qauv hlau, cov hlau siv hauv cov kav dej kub tsis tshua muaj siab muaj qhov zoo ntawm lub zog siab, kev ua haujlwm zoo, kev ua haujlwm ntev, kev siv ntau yam, thiab kev lag luam. Cov hlau no feem ntau yog dov rau hauv daim hlau, profiles, seamless steel kav, thiab lwm yam, thiab nws yog dav siv nyob rau hauv choj, nkoj, boilers, tsheb thiab lub tsev tseem ceeb.
Cov khoom siv feem ntau siv rau cov raj cryogenic: Q345B, Q345C, Q345D, Q345E,A333Gr6.
