Tianjin Lined Industrial Co., Ltd yog ib qho ntawm cov neeg tsim khoom thiab cov chaw muag khoom ntawm ASTM A1085 Hollow Cov Lus Qhia (HHS) hauv Suav teb. Thov koj xav tau cov khoom siab zoo ast as t t85 hollow cov lus (HHS) los ntawm peb lub hoobkas. Cov kev pabcuam zoo thiab tus nqi tsim nyog muaj.
Lub hauv paus rau phau ntawv
ASTM A1085 yog tus qauv tshwj xeeb rauCold - yawm, welded, siab {{1} {{{{}} almoy qauv tubingNyob rau hauv puag ncig, square, thiab duab plaub, npaj rau siv hauv cov ntawv thov txheej txheem. Qhia rau hauv 2013, nws sawv cev rau txoj kev nce qib tseem ceeb dua A500 los ntawm kev ua tiav kev ua tau zoo, thiab txhim kho durability.
Tus qauv no tau tsim los ntawm kev sib koom tes ntawm American Institute ntawm American Institute ntawm American Institute ntawm American Institute ntawm lub koom haum Steel (STRIs
Cov yam ntxwv tseem ceeb
Siab zog - rau - qhov hnyav nyhav:
A1085 qhia meej aYam tsawg kawg cov paib lub zog (FY) ntawm 50 KSI (345 MPA)thiab aYam tsawg kawg tensile lub zog (Fu) ntawm 62 ksi (427 mpa)Cov. Qhov no siab dua li cov qhab nia raug nyob hauv A500 (qib B: FY {}} {} {{5}- cov qauv ua tau zoo.
Txhim kho ductility thiab tawv:
Nws yuav tsum muajyam tsawg kawg nkaus elongation ntawm 18%, uas yog siab dua qhov yuav tsum tau rau A500. Qhov no ua kom pom tseeb cov hlau yog ntau dua cov yas, lub ntsiab lus nws tuaj yeem yauv tsis txaus ntseeg ua ntej kev sib tw ua ntej kev nqus cov xwm txheej lossis kev tiv thaiv ncaj.
Cov txheej txheem stricter tshuaj (chemistry):
A1085 muaj kev tswj hwm ntawm cov tshuaj zoo li cov pa roj carbon, phosphorus, thiab leej faj. Nws kuj tseem suav nrog cov kev txwv ntau tshaj plaws rau cov pa roj carbon sib npaug (CE) kom ntseeg tau tiasZoo heev WeldabilityThiab kom txo qis kev pheej hmoo ntawm kev tawg hauv tshav kub -}} cuam tshuam cheeb tsam thaum lub sijhawm fabrication.
Superior qhov seem tiv thaiv:
Lub tiaj rau tus ntoo hlav - ntu ntu qhov ntev (piv txwv li, sab nraud qhov ntev, phab ntsa tuab) thiab cov ntawv ncajtighter thiab nruj npaum li nrujtshaj li cov rau A500. Qhov no ua rau cov tswv cuab uas muaj kev sib txuam thiab paub tseeb, uas yooj yim fabrication thiab haum} li, tshwj xeeb tshaj yog nyob rau hauv cov nyom sib txuas.
Kev siv cov lus tau teev tseg tsawg kawg yog kom muaj zog:
Qhov no yog qhov tseem ceeb rau cov qauv tsim qauv qauv. AISC steel tsim phau ntawv pub cov neeg tsim tawm los siv covTag Nrho Cov Lus Qhia Tsawg Tshaj Tawm Lub Zog Zog (50 Ksi)Nyob rau hauv lawv cov kev suav tsis muaj lub zog txo cov yam yuav tsum muaj rau A500 cov khoom siv. Qhov no ua rau yooj yim dua, ntxiv ncaj qha, thiab tsim qauv ntau dua.
Cov Ntawv Thov
Cov khoom siv txhim kho ntawm ASTM A1085 hss ua rau nws zoo tagnrho rau kev thov kev ua tau zoo, ua tau zoo, thiab kev ntseeg tau yog qhov tseem ceeb:
- Seismic -} tiv taus framing:Nws txoj kev ua qauv siab thiab tawv ua rau nws xaiv zoo rau lub sijhawm thav ntawv thiab braced thav ntawv -} cov cheeb tsam.
- Ntev -} span trusses thiab arches:Lub zog siab - rau - Qhov hnyav} qhov hnyav dua nrog rau kev sib tw ntev dua.
- High -} Rose vaj tse:Siv los ua cov kab ntawv thiab kev zawm hniav, uas txuag tau qhov hnyav ntawm cov tsev sab saud tuaj yeem muaj cov teeb meem tseem ceeb ntawm cov qauv txheej txheem.
- Cov kab hluav taws xob hnyav hnyav:Kev sib xyaw ua ke ntawm lub zog siab thiab kev ductility zoo muab cov kev daws teeb meem loj dua rau kev txhawb nqa loj.
- Cov Cheebtsam Choj:Siv nyob rau hauv ntau tus neeg choj nyob qhov twg ruaj khov thiab kev ua tau zoo.
- Kev tsim kho vajtse nthuav tawm cov qauv hlau (AESS):Qhov nruj ntev ntev ntev ua rau cov kab sib tov thiab zoo dua, ua rau nws tsis haum rau qhov chaw uas yog txhob txwm tso rau kev ua kom zoo nkauj rau cov laj thawj zoo nkauj.

Lub ntsiab
- vs. A500:Thaum qib A500 C muaj tib luam tawm tsawg kawg los lub zog zog (50 ksi),A1085 yog cov khoom lag luam zoo dua hauv yuav luag txhua txoj kev.Nws tuaj yeem lav tau zoo dua qub, nruj chemination tswj kev vuam, thiab stricter qhov ntev tances. Qhov tseem ceeb, rau kev tsim qauv, A1085 tso cai rau kev siv tag nrho 50 KSI tawm lub zog, hos ib500 yuav tsum tau txo, ua A1085 cov khoom siv A1085 ntau dua.
- vs. A501:A501 yog tus txheej txheem qub rau kub -} tsim cov tubing. Nws muaj tsawg dua cov txiaj ntsig zoo zog zog (36 ksi) thiab feem ntau tsis zoo sab nraud ntawm cov khoom. A1085 (thiab A500) tau hloov ntau dua A501 rau cov ntawv thov feem ntau vim lawv cov khoom zoo dua thiab ntau dua.
Hauv kev xaus,ASTM A1085 yog tus hwm, siab-} Performance hssTsim rau niaj hnub, txuag, thiab resilient qauv qauv tsim. Nws muaj cov txiaj ntsig tau txaus tshaj A500 thiab A501, tshwj xeeb tshaj yog siv tau los tsim kev nyab xeeb, sib dua, thiab ntau dua kev lag luam.
