Cov hlau chromium siab ua los ntawm cov khoom siv ceramic composite roller yog ua los ntawm cov hlau chromium siab ua cov khoom siv matrix, los ntawm cov txheej txheem tshwj xeeb, cov hlau chromium siab thiab cov khoom siv honeycomb ceramic composite molding, cov khoom siv ceramic ZTA, thiab tom qab ntawd los ntawm cov txheej txheem xuab zeb casting, cov hlau chromium siab ua los ntawm cov khoom siv ceramic composite thiab cov hlau ductile theem nrab molding.
Cov tshuaj lom neeg muaj pes tsawg leeg ntawm cov khoom siv hlau chromium siab tau qhia nyob rau hauv Rooj 1 hauv qab no.
Rooj 1: Cov tshuaj lom neeg muaj pes tsawg leeg ntawm cov hlau sib xyaw ua ke uas muaj chromium siab (wt%)
| Khoom siv | C | Si | Mn | S | P | Cr |
| Cov log tsheb sib xyaw ua ke nrog cov chromium siab heev | 2.8-3.2 | 0.5-1.0 | 0.5-1.2 | ≤0.05 | ≤0.05 | 20-26 |
| Hlau nplaum | 3.2-3.9 | 2.5-2.7 | 0.3~0.5 | ≤0.04 | ≤0.04 |
