Nkag siab DIN St52-3 Hlau: Keeb Kwm thiab Khoom
DIN ST52 - 3 yog tus qauv qis-alloy. Nws paub txog nws qhov zoo heev weldability, muaj txiaj ntsig zoo zog, thiab zoo machinability.
Cov khoom tseem ceeb ntawm cov qauv ntawm ST52-3-3 xws li:
- Tawm Zog: Yam tsawg kawg yog 35 MPA (rau thicknesses txog li 16 hli)
- Tensile lub zog: 490-630 MPa
- Elongation: tsawg kawg 22%
- Kev Cuam Tshuam: Zoo nyob rau hauv chav tsev kub, nrog cov variants zoo li St52-3n muab cov khoom siv rau qhov zoo rau qhov zoo dua.
Cov qib qib no feem ntau tau teev nyob hauv Europe rau choj, vaj tse, thiab khoom siv hnyav. Yog tias koj tau nug "thaj chaw ntawm DIN St52}} 3 qauv steel," Nco ntsoov tias nws tsis yog ib txwm muaj rau kev ua tau zoo.
Qhov ze tshaj Astm sib npaug: A572 Qib 50
Raws li cov ntoo khaub lig uas dav {{0} Hais txog cov qauv zoo li din
Vim li cas A572 Qib 50?
Nws yog qhov siab - lub zog, qis {{{{{}} aliumium- vanadium qauv qauv hlau.
Feem ntau siv nyob rau hauv Asmeskas rau Welded choj, vaj tse, thiab cov cuab yeej siv siv, tsom iav ST52-3 USES.
Thaum tsis zoo ib yam (vim qhov sib txawv me ntsis hauv cov tshuaj muaj tshuaj), nws tau lees txais raws li kev hloov pauv hauv cov dej num thoob ntiaj teb.
Rau cov kev tshawb nrhiav "ASTM A572 Qib 50 sib npaug rau St52-3, "Ntawm no yog lub rooj sib piv sai:
Yog li koj paub, ib txwm txheeb xyuas nrog cov kev qhia tshwj xeeb, raws li kev sib txig sib luag yog txawv ntawm thickness thiab kev kho cua sov. Rau "DIN ST52-3 Tshuaj Yeeb VS ASTM ATTM A572 Qib 50," Sab laj cov qauv tag nrho rau cov ntsiab lus zoo.
Lwm cov kev sib tw Astm muaj xws li A633 (rau cov xwm txheej AN63W) lossis qib ece7 yog qhov mus - rau cov qauv kev siv dav dav.
Yog vim li cas cov khoom sib npaug hauv cov saw ntiaj teb
Niaj hnub no txoj kev sib tham sib txuas lus niaj hnub no, paub txog "cov sib npaug thoob ntiaj teb rau cov qib ST52-3 pab zam kom tsis txhob qeeb. Piv txwv li, yog tias koj nyob hauv Asmeskas sourcing European qauv tsim, hloov mus rau ASTM A572 qib 50 tuaj yeem tawm cov kev pom zoo thiab txo qis cov kev pom zoo. Kuv tau pom cov dej num txuag tau 15-20% rau cov nqi los ntawm kev siv sib txig hauv zos yam tsis muaj kev sib txawv.

Cov FAQ
Q: Dab tsi yog tus txheej txheem DIN rau ST52?
A: ST52 hlau (ST52-3) yog ib qho qauv siv hlau tsis tau raug muab pov tseg txij li xyoo ST52-3u (1.0553) thiab ST52-3N (1.0570 khoom).
Q: Qhov sib txawv ntawm A36 thiab ST52 li cas?
A: ST52 muaj qhov muaj txiaj ntsig ntau dua thiab tensile lub zog piv rau A36, ua kom haum rau cov ntawv thov ntau dua uas yuav tsum muaj zog dua. Kev sib xyaw: A36 muaj cov ntsiab lus carbon ntau dua piv rau ST52, thaum ST52 muaj ntau dua Manganese cov ntsiab lus uas ua rau nws lub zog.
Q: Dab tsi yog qhov sib txawv ntawm C45 thiab ST52-3?
A: ST52 vs c45. Cov qhab nia 1.0570 muaj ntau molybdenum nyob rau hauv nws cov ntsiab lus alloy tshaj li C45 qib, muab nws tsis kam tshaj. Niobium, titanium, thiab vanadium tau muaj nyob rau hauv ntau dua cov qib 2391 ST52 qib kawm dua nyob rau qib C45.
Q: Dab tsi yog cov txiaj ntsig lub zog ntawm st52-3-3?
A: 355 MPa
