Cov khoom lag luam
Peb Super DupleX Kev Kawm Ntawv (S32750 qib) xa cov kev ua tau zoo hauv cov chaw hnyav. Nrog 25% chromium thiab 7% muaj pes tsawg xyoo (A Astm A320), cov suplex bolts tiv thaiv corrosion 3x zoo dua cov qauv 316 stainless. Lub nitrogen-enhanced mis (0.28% min.) Ua tiav 1000 MPA tensile lub zog - uas yog 40% ntau dua li cov duplex fasteners. Kev Kuaj Rau Neeg (ASTM G48 Txuj Ci C) Tshaj tawm Xoom Pitting Tom qab 300 teev nyob rau hauv 6% Ferric chloride ntawm 50 degree. Txog rau ntug dej lossis tshuaj chemical, qhov no txhais tau15+} xyoo kev pab lub neej uas cov roj carbon steel ua tsis tau cov hlau.
SUPLERTXD STUPLE KHW Hoobkas Zauv
Txhua tus batch undergoes precisat txias zam txim (lub taub dej tsis kam ± 0.05mm rau ib asme B18.2.6) Thiab lim hwv-hardening rau kev ua kom zoo ib yam rau txoj xov zoo ib yam. Peb muab ob qhov tseem ceeb ua tiav:
Passivation ib astm A967: tsim 10μm chromium oxide txheej, txo cov kev pheej hmoo corrosion los ntawm 50%
Electro-polishing (ra tsawg dua los yog sib npaug rau 0.2μm): minimizes sib txhuam thaum nruab hnub teeb tsa thaum txhim kho chloride tiv taus
100% sib nqus particetic kuaj (Astm E709) pom cov nplaim pov tseg ua ntej ua zaub mov xa tuaj.
Ntau lawm lub zog
Peb Lub Chaw Henan ua haujlwm 18 lub zog txias-tsim cov kab ua ke nrog lub peev xwm txhua xyoo ntawm 800 lab tus dua ntawm lub zog ntawm 800 lab daus las. Real-lub sij hawm tswj cov txheej txheem kom ntseeg tau:
- Hardness sib xws: 30-35 hrc thoob plaws txhua lub batches (sim teev)
- TSOOM SIGMA-THOJ: Cov ntsiab lus Intermetallic<0.5% (verified per ASTM A923 Method C)
- Tag nrho traceazeobility: laser-cim cov me nyuam cua kub + khoom siv khoom siv (en 10204 3.1)
- Nrog 2000+ pallet txoj haujlwm rau M12-M64 Bolts, peb lav 48-teev thauj khoom rau cov qauv xaj.
Tuam Txhab Koom Tes
Kev txiav txim 5+ tons thiab tau txais:
Cov Ntawv Qhia Txog Ntsev Dawb Kev Tshuaj Ntsuam Xyuas (ISO 9227) nrog koj cov zaub mov xa tuaj
