A709 H Zoo Li Tus Hlau

 

 

A709 H nqaj yog lub siab-zog, cov hlau tsis muaj zog (HSLA) uas tau sib ntsib ntawm cov qauv ASTM thiab yog tsim rau cov qauv siv hluav taws xob, tshuab hnyav thiab tsim cov ntawv.

 

Lub ntsiab nta ntawm A709 qauv hlau H nqaj

Lub zog siab: tawm lub zog ntau dua los yog sib npaug ntawm 485 MPa, ua kom muaj peev xwm ua kom muaj peev xwm loj dua lossis sib npaug ntawm cov khoom muaj peev xwm lossis kev sib npaug ntawm cov khoom muaj peev xwm lossis kev sib npaug ntawm cov khoom muaj peev xwm lossis kev sib npaug ntawm cov khoom siv.
Huab cua tiv thaiv: Ua cov txheej xeb-pov thawj tiv thaiv cov atmospheric corrosion thiab txo cov kev xav tau.
Weldability thiab machinancability: tsawg cov ntsiab lus carbon (tsawg dua los yog sib npaug ntawm 0.
Cov khoom siv efficiency: Txuag 15-40% ntawm cov khoom siv siv thaum khaws cov qauv txheej txheem piv rau cov nqaj hlau.

 

Tshuaj Muaj Tshuaj

Cov alloys ntawm A709 H-nqaj muaj xws li:
Cov pa roj carbon (c): tsawg dua lossis sib npaug rau 0. 23%
Manganese (MN): {0. {80-1. 50%
Tooj (CU): tsawg dua los yog sib npaug rau 0. 40%
Phosphorus (p): tsawg dua lossis sib npaug rau 0. 04%
Silicon (Si): {0. {15-0. 50%
Cov ntsiab lus ntxiv xws li chromium (CR) thiab npib tsib caug (NI) txhim kho corrosion tsis kam thiab tawv.

Cov Ntawv Thov

A709 H-BEAMS tau siv dav hauv:

Choj tsim kev tsim tsim: Siv nyob rau hauv cov nqaj tseem ceeb, cov piers thiab txhawb nqa cov qauv vim muaj lub zog siab thiab corrosion tsis kam.

Kev Tsim Kho: Lub Hoobkas thav duab, chaw khaws ntaub ntawv thiab sab nrauv platform uas yuav tsum muaj kev npau suav tsis txaus ntseeg.

Crane nkoj, crane booms thiab lub tsheb chassis.

Av qeeg--prone: txhim kho cov qauv kev ruaj ntseg ntawm cov chaw nyob thiab ua lag luam.
