Qhov Zoo

Siab Zog
Cov txiaj ntsig lub zog ntawm peb cov khoom lag luam yog feem ntau tsis pub tsawg tshaj li 600 mpa, thaum lawv lub zog tensile tuaj yeem ncav cuag 620-850 MPa. Lub zog no ua kom ntseeg tau cov qauv zoo heev nyob hauv cov nra hnyav.

Zoo tougnness
Cov phiaj xwm HQ600 Cov Peel Roj Hlau Ua rau pom kev cuam tshuam zoo heev thiab khaws cov qib ntawm kev nruj me me hauv qhov chaw tsawg. Piv txwv li, ntawm qhov kub tsawg ntawm {2}} degree, tiv thaiv kev puas tsuaj ntawm cov kev puas tsuaj los ntawm kev puas tsuaj rau kev puas tsuaj.

Zoo heev Weldability
Peb cov phiaj hlau siv hluav taws xob muaj cov pa roj carbon ntau (feem ntau tsawg dua 0. 5), uas ua kom muaj txiaj ntsig zoo vuam kev ua tau zoo. Thaum lub sij hawm vuam, nyiam ua cov kab nrib pleb txias yog qhov tsawg, kom ntseeg tau lub zog thiab kev ntseeg tau ntawm cov pob qij tw welded.

Zoo corrosion tsis kam
Tom qab galvanizing, peb cov phiaj hlau ua hluav taws xob tiv thaiv cov atmospheric thiab dej hiav txwv corrosion. Qhov nruab nrab thickness ntawm galvanized txheej yog 50-100 μm, muab ntau tshaj 15 xyoos, muab ntau tshaj li 15 xyoos ntawm kev tiv thaiv marine thiab nthuav tawm kev pabcuam lub neej ntawm cov khoom siv.

Yooj yim rau cov txheej txheem thiab cov duab
Cov khoom no muaj cov khoom txias heev thiab cov cua kub thiab haum rau kev tsim los ntawm ntau cov txuj ci xws li forging, khoov, thiab stamping. Nws cov khoom siv ua tau zoo txo qis dua cov kev sib nraus lossis deformation thaum cov txheej txheem sib xyaw ua ke lossis cov qauv loj, thaum tswj hwm cov kev ua haujlwm siab.
