Q345B daim ntawv thov
Q345B yog qhov qis -} Alloy alloy, siab- lub zog steel teev nyob rau hauv Suav teb chaws (GB / T 1591). Nws muaj lub zog nruab nrab (tawm kom lub zog loj dua los yog sib npaug rau 345 MPa), kev siv zog weldability zoo, thiab kev sib tw zoo. Nws yog dav siv nyob rau hauv ntau yam teb, suav nrog kev tsim kho, Machinery, tsheb thauj mus los, thiab kev cog lus. Daim ntawv thov tshwj xeeb yog raws li hauv qab no:
1. Kev tsim kho thiab cov txheej txheem tsim tawm
Cov qauv hlau: siv nyob rau hauv load - cov kabmob hlau thiab kev txhawb nqa cov khoom siv ntawm cov chaw ua haujlwm thiab cov khoom siv siab}}}}}} Rose tsev. Hloov cov khoom tsoos tsawg -} cov hlau roj carbon hlau (xws li Q235) txo cov teeb meem hnyav thiab txhim kho seismic tiv taus.
Txuas hniav thiab chaw tsim khoom lag luam engineering: haum rau cov nqaj tseem ceeb thiab cov choj me me) thiab txhawb nqa cov raj dej hauv nroog (xws li muaj peev xwm siv tau qee qhov kev ntsuas thiab ib puag ncig.
Ntauwd qauv: siv nyob rau hauv cov yees thiab txuas ntawm kev sib txuas lus cov yees thiab huab cua tsis zoo (uas tuaj yeem txhim kho los ntawm kev kho mob deg)}} machinery manufacturing thiab khoom siv
Cov Khoom Siv Hluav Taws Xob General Machinery: Siv nyob rau hauv kev tsim cov tshuab cuab yeej (Crane Boots, yuav tsum tau ua kom lawv lub zog siab tiv thaiv lawv lub zog kom txo tau qhov hnyav ntawm cov khoom siv.
Qhov hnyav Machinery Qhov chaw: Cheebtsam xws li cov npoo av thiab caj npab ntawm cov thawv ntim khoom thiab cov tsheb laij teb thiab cov tsheb laij teb khoov hauv kev ntxhov siab.
3. Tsheb thauj mus los
Automotive manufacturing: feem ntau siv nyob rau hauv chasitis cov qauv sib xyaw (subframes
Kev Thauj Khoom thiab Rail Transit: Tsim kom haum rau hull cov qauv thiab nruab nrab {{{{cov nkoj me me, ntxiv rau cov tsheb ciav hlau thiab cov txuas rau subways thiab lub teeb ntsia. Cov feem xyuam no yuav tsum tau anti - kev kho corrosion (xws li pleev xim thiab galvanizing tso cov puag ncig.
4. Lwm cov ntawv thov muaj
Cov thawv ntim khoom thiab cov khoom siv ua haujlwm: cov thav duab thav duab yuav tsum tau ua kom cov kev thauj mus los thiab qhov cuam tshuam ntawm kev thauj mus los. Pipelines thiab Siab Hlab Hlo: Siv rau hauv kev tsim cov nruab nrab {{1} Txoj kev xav tau cov roj av (chav nyob qhov kub thiab qis dua lub zog loj dua los yog sib npaug rau 34.
Lub ntsiab
Q345B cov tseem ceeb tau nyob hauv nws qhov sib npaug ntawm lub zog thiab ua haujlwm. Nws tuaj yeem tiv thaiv ntau dua cov kev thauj khoom zoo dua li qub qis {2} {-}}} ecloy ecoy} ecloy ecoy Qhov no ua rau nws "General {- lub hom phiaj" tsawg}}} allo practural cov qauv hlau hauv lub zog, weldability}, weldability, thiab tus nqi.
