Nws yog siv dav hauv cov lag luam uas xav tau kev ua tau zoo, kev ua haujlwm raug, thiab kev ntseeg siab, suav nrog aerospace, automotive, kev tsim kho, marine, petrochemical, lub zog, thiab kev tiv thaiv.

Tsab xov xwm no tshuaj xyuas cov yam ntxwv ntawm cov hlau tshwj xeeb, nws txawv li cas ntawm cov hlau ib txwm, nws qhov kev faib tawm, thiab vim li cas nws thiaj li tseem ceeb rau cov ntawv thov engineering siab heev.

Hlau Tshwj Xeeb Yog Dab Tsi?

Cov hlau tshwj xeeb yog cov hlau uas tau muab ib lossis ntau yam khoom sib xyaw ua ke xws li chromium, nickel, molybdenum, vanadium, tungsten, lossis cobalt. Cov kev ntxiv no txhim kho cov yam ntxwv xws li lub zog, qhov nyuaj, kev tiv thaiv xeb, kev tiv thaiv kub, thiab kev tiv thaiv kev hnav.

Cov hlau tshwj xeeb feem ntau yog tsim tawm hauv qab kev tswj hwm zoo, ua tau raws li cov tshuaj lom neeg muaj pes tsawg leeg thiab cov khoom siv kho tshuab uas tau txhais los ntawm cov qauv thoob ntiaj teb xws li ASTM, EN, JIS, thiab DIN.

Cov Yam Ntxwv Tseem Ceeb ntawm Cov Hlau Tshwj Xeeb

1. Muaj Zog Siab

Cov hlau tshwj xeeb feem ntau muaj zog tensile thiab yield zoo dua li cov hlau carbon ib txwm. Cov khoom sib xyaw thiab cov txheej txheem kho cua sov ua rau cov hlau muaj peev xwm tiv taus cov khoom hnyav yam tsis muaj deformation. Qhov no ua rau nws zoo tagnrho rau cov khoom tseem ceeb xws li cov khoom siv tshuab, shafts, thiab iav.

2. Kev Txhim Kho Hardness thiab Hnav Resistance

Cov khoom xws li carbon, chromium, thiab vanadium txhim kho qhov tawv, ua rau cov hlau tshwj xeeb tsim nyog rau cov cuab yeej, cov cuab yeej txiav, thiab cov khoom siv tshuab uas tiv taus kev hnav. Cov hlau cuab yeej thiab cov hlau bearing yog cov piv txwv zoo ntawm cov qib siab tawv.

3. Kev Tiv Thaiv Kev Sib Tsoo Zoo heev

Cov hlau tsis xeb thiab qee cov hlau sib xyaw ua ke tiv taus xeb thiab tshuaj lom neeg vim muaj chromium thiab nickel. Cov hlau no siv dav hauv kev lag luam marine, tshuaj lom neeg, thiab kev ua zaub mov.

4. Kev Tiv Thaiv Kub Zoo Tshaj Plaws

Cov hlau tshwj xeeb uas tiv taus cua sov tswj tau lub zog thiab kev ruaj khov ntawm qhov kub siab. Lawv siv rau hauv cov chaw tsim hluav taws xob, cov cub tawg, thiab cov cav aerospace qhov twg kev ruaj khov thermal yog qhov tseem ceeb.

5. Kev Nyuaj Siab Siab

Kev tawv yog lub peev xwm nqus tau lub zog thiab tiv taus kev tawg. Cov hlau tshwj xeeb tseem muaj kev tawv siab txawm tias nyob rau hauv qhov kub qis, ua rau lawv tsim nyog rau kev siv cryogenic.

6. Kev Siv Tau Zoo thiab Kev Tsim Tau Zoo

Qee cov hlau tshwj xeeb yog tsim los kom muaj kev sib npaug ntawm qhov nyuaj thiab kev siv tau yooj yim, ua rau muaj kev tsim khoom raug nrog kev siv cov cuab yeej tsawg dua.

7. Cov Tshuaj Lom Zem Tseeb

Cov hlau tshwj xeeb raug tsim tawm nrog kev tswj hwm nruj ntawm cov tshuaj lom neeg sib xyaw, ua kom muaj kev ua tau zoo sib xws thoob plaws hauv cov pawg. Qhov kev ua kom raug no yog qhov tseem ceeb rau cov lag luam uas xav tau cov txiaj ntsig rov ua dua.
