1. Hnav tsis kam. Thaum cov hlau plastically denatured hauv cov pwm kab noj hniav, nws rubs thiab sib tsoo raws cov kab noj hniav, ua rau muaj kev sib txhuam loj ntawm cov kab noj hniav thiab cov hlau, uas tej zaum yuav ua rau lub pwm puas vim hnav.
2. Corrosion tsis kam.
3. Grindability. Tus kwv tij poob ntawm kev sib tsoo lub log yog qhov me me, qhov siab tshaj plaws ntawm kev sib tsoo tsis muaj qhov hlawv yog loj, thiab nws tsis rhiab rau qhov zoo ntawm kev sib tsoo lub log thiab qhov txias txias, thiab nws tsis yooj yim los ua kev puas thiab kev sib tsoo.
4. Lub cev tawv steel thiab lub zog.
5. Tshuaj tua kab mob antioxidant, rhiab heev rhiab rhiab heev.
6. Kub tsis kam. Yam uas yuav tsum muab los txiav txim siab li saum toj no
7. Kev ua txheej txheem tshwj xeeb.
8. Nkees nkees nkees nkees zog. Hauv kev tsim cov txheej txheem ntawm txhuas ntawv ci phaj pwm , nyob rau hauv kev ua ntawm kev sib tsoo ntev thiab kev sib txhuam, kev qaug zog ua rau feem ntau tshwm sim.
9. Mouldability. Cov cuab yeej tuag steel dua li muaj kub kub forging deformation tsis kam thiab plasticity zoo.
10. Kev ruaj khov. Nws muaj teeb thiab zoo li saum npoo tawv thiab kev ua haujlwm zoo tom qab quenching.
