Qhov zoo: Txhim kho los ntawm cov tsoos H13, zoo machinability, dav siv hauv cov khoom tseem ceeb xws li nozzles thiab manifolds.
2. Intrinsically Fine-Grained Steel
Al-Killed H13 (Aluminium Deoxidized H13): Tshem tawm cov nplej coarsening thaum lub sij hawm cua sov los ntawm AlN dispersion, kom ntseeg tau ib tug zoo thawj microstructure (qib 5–8), ua nws thawj xaiv rau pwm tshiab.
Fine-grained 4Cr5MoSiV1: Ib qho zoo, zoo-grained microstructure yog tau los ntawm kev tswj deoxidation thaum smelting.
Nta: Tsis xav tau cov alloys kim, tus nqi siab -kev ua tau zoo, haum rau ntau lawm.
3. Powder Metallurgy Steel (High-Kev siv kawg)
PM-H13: Siv cov hmoov metallurgy thev naus laus zis, ua tiav cov qoob loo thawj zaug ntawm 8-10, nrog cov khoom siv carbide tsis tshua muaj siab thiab muaj kev tiv thaiv zoo rau cov qoob loo loj hlob piv rau cov tsoos steels.
ASP-23 (High-Speed Steel): Muaj cov qib siab ntawm V thiab Mo, nrog rau ultra-zoo microstructure thiab ntau dispersed carbides, pom zoo heev kub-kub kuj.
Qhov zoo: Zoo isotropy, qaug zog lub neej ntau dua 30% siab dua, haum rau precision txhaj pwm hauv kev kho mob thiab kho qhov muag.
4. Thaum tshav kub kub-resistant alloys (ultra-cov ntaub ntawv kub)

Nco tseg: Tus nqi siab, ua haujlwm nyuaj, feem ntau yog siv los hloov cov khoom tseem ceeb.
5. Ceramic matrix composites (txiav-kev tshawb fawb ntug)
SiC/SiC, Al₂O₃/ZrO₂: Hlau -dawb grain qauv, kub tsis kam tshaj 1400 degree, yuav luag tsis muaj thermal deformation.
