H13 steel yog feem ntau siv thiab sawv cev kub ua haujlwm tuag hlau. Nws cov yam ntxwv tseem ceeb yog:
(1) Nws muaj siab hardenability thiab siab toughness.
(2) Kev tiv thaiv zoo heev rau thermal tawg, dej txias tuaj yeem siv rau hauv chaw ua haujlwm.
(3) Nrog rau nruab nrab hnav tsis kam, carburizing lossis nitriding kuj tuaj yeem siv los ua kom cov tawv nqaij tawv, tab sis cov thermal tawg yuav tsum tau txo qis me ntsis.
(4) Vim nws cov ntsiab lus carbon tsawg, lub peev xwm hardening thib ob thaum tempering tsis zoo.
(5) Nws muaj peev xwm tiv taus softening ntawm qhov kub siab dua, tab sis lub hardness poob sai heev thaum siv kub siab tshaj 540 degree (1000 degree F) (uas yog, muaj peev xwm ua hauj lwm kub yog 540 degree).
(6) Lub deformation ntawm kev kho cua sov yog me me.
(7) Nruab nrab thiab siab machinability.
(8) Nruab nrab tsis kam rau decarburization.
