Kub-ua haujlwm tuag steel yog ib pawg ntawm cov cuab yeej hlau alloy tshwj xeeb tsim los rau kev ua haujlwm siab ntawm cov hlau kub lossis cov hlau molten nyob rau hauv siab - qhov kub thiab txias; Nws yog feem ntau siv los tsim cov pwm rau kev siv xws li kub forging, kub extrusion, thiab tuag casting.
Feem ntau muaj nyob nruab nrab ntawm 0.3% thiab 0.6% carbon, cov hlau no tau muab faib ua nruab nrab - carbon alloy steels. Lawv yog alloyed nrog cov ntsiab lus xws li Cr, W, Mo, thiab V kom tau raws li kev ua tau zoo, nrog rau siab - kub lub zog, tiv thaiv thermal qaug zog, zoo thermal conductivity, hnav tsis kam, thiab oxidation kuj.
