Qhov Zoo Tshaj Plaws
Synergistic alloying nrog tooj liab, Chromium, thiab Nickel ua rau xeb ruaj khov -zoo li patina uas tiv thaiv cov hlau matrix los ntawm kev degradation ntxiv yam tsis muaj txheej txheej thib ob.
Ua tau raws li nruj Charpy V-cov kev xav tau ntawm lub zog nqus, ua rau nws tsim nyog rau kev puas tsuaj loj heev -tseem ceeb thiab tsis yog- pob txha- qhov tseem ceeb choj cov khoom nyob rau hauv txias - huab cua puag.
Muab qhov kev lees paub qhov tsawg kawg nkaus lub zog ntawm 345 MPa (50 ksi), txo qhov hnyav ntawm cov qauv thaum tswj kev ruaj ntseg.
Formulated nrog tswj cov pa roj carbon sib npaug (Ceq) kom tso cai rau kev txhim khu kev lag luam vuam, oxy- roj txiav, txiav cov ntshav, thiab kev ua txias txias siv cov txheej txheem hauv khw.

Vuam & Fabrication Guidelines
Cov txheej txheem vuam:Yooj yim welded siv tus qauv Shielded Hlau Arc Vuam (SMAW), Flux-Cored Arc Vuam (FCAW), thiab Submerged Arc Vuam (SAW).
Consumables:Txhawm rau ua kom lub vuam seam txhim kho qhov sib piv huab cua thiab lub zog, sib piv cov khoom siv qis qis (xws li E8018-W lossis AWS A5.28 ER80S-W) raug pom zoo rau cov ntawv hla dhau.
Kev tsim:Kev kho mob txias yuav tsum tau ua raws li ASTM A6 tus qauv khoov radii cov lus qhia.
Hauv -House Quality Assurance
Kev kuaj ultrasonic (UT):100% volumetric soj ntsuam raws li ASTM A435 / ASTM A578 Qib A / B los lav kev ywj pheej los ntawm cov laminations sab hauv.
Dimensional & Surface Tolerances:Tswj tau raws li ASTM A6 / A6M tus qauv.
Traceability:Thaum tshav kub kub thiab qib steel yog ib qho nyuaj mus tas li - stamped rau txhua daim phaj, tag nrho txuas rau MTC nrog.
Export Ntim & Maritime Thauj Kev Nyab Xeeb
Surface Treatment & Protection:Maj mam oiled, ntshiab lacquered, los yog qhwv hauv hnyav -cov ntaub ntawv tsis muaj dej tsis zoo thaum thov.
Bundling & Corner Guarding:Cov hlua khi siv hnyav- lub luag haujlwm steel bands nrog yas ntug tiv thaiv; mounted rau cov ntoo pallets muaj zog los yog steel khiav rau forklift thiab crane tuav.
Container & Breakbulk Lashing:Kev ruaj ntseg hauv cov thawv los yog cov khoom tawg tau tuav nrog hnyav- lub luag haujlwm lashing siv, tiv thaiv- cov roj hmab mats, ntoo dunnage, thiab cov hnab ntim desiccant los tiv thaiv kev ya raws.
Kev Tshawb Fawb & Cov Ntaub Ntawv
EN 10204 3.1 MTC:Tshaj tawm ncaj qha los ntawm zeb's QA lab, piav qhia txog cov cua sov chemistry, cov txiaj ntsig kev siv tshuab, cuam tshuam qhov tseem ceeb, thiab ntawv pov thawj UT.
Thib peb-Kev Tshuaj Xyuas Tus Kheej (TPI):SGS, BV, LR, lossis ABS kev tshuaj xyuas tau txais kev txhawb nqa raws li tus neeg thov.
System Certifications:ISO 9001: 2015, ISO 14001: 2015, ISO 45001: 2018, CE Marking (EN 1090-1).
