DIN 17100 St52.3 cov yeeb nkab steel hlau raug xa mus rau Australia.
DIN 17100 yog tus qauv siv rau cov seem steel, steel tuav, hlau rods, khoom tiaj tusseamlessthiab welded, square thiab rectangular hollow seem, forgings, thiab semi-tiav khoom nyob rau hauv cov qauv steels uas yog xa nyob rau hauv lub kub tsim los yog normalized mob tom qab ntau lawm.
St52.3 yog ib qho ntawm cov qib, thiab cov khoom siv yog 1.0570.
Ua ntej xa khoom, Botop npaj rau cov neeg ua haujlwm zoo los ua tib zoo tshuaj xyuas cov khoom kom ntseeg tau tias cov khoom zoo ua tau raws li cov neeg siv khoom xav tau.
Ua ntej, qhov zoo ntawm qhov chaw, qhov dav, qhov siab, qhov ntev, squareness, thiab lwm yam zoo li qhov ntev ntawm cov yeeb nkab steel yog ua tib zoo tshuaj xyuas kom ua raws li cov qauv thiab cov neeg siv khoom.
Tom ntej no, cov tshuaj lom neeg thiab cov khoom siv ntawm cov yeeb nkab steel hlau raug kuaj xyuas.
EN 17100 St52.3 muaj cov kev cai hauv qab no:

Cov tshuaj muaj pes tsawg leeg ntawm St52.3 yog ntsuas los ntawm spectrometer, thiab tag nrho cov ntsiab lus raws li cov neeg siv khoom xav tau piv rau cov kev xav tau.
Cov khoom siv kho tshuab ntawm EN 17100 St52.3 feem ntau suav nrog lub zog tensile thiab lub zog tawm los, uas ntsuas los ntawm kev ntsuas tensile.

Tom qab ua tiav tag nrho cov kev tshuaj xyuas thiab xyuas kom meej tias qhov ua tau zoo raws li tus qauv yuav tsum tau muaj, daim ntawv pov thawj Material Test (MTC) raug muab. Tom qab ntawd, kev npaj tau npaj rau kev xa khoom thiab lwm yam haujlwm.
Txij li thaum nws tsim nyob rau hauv 2014, Botop Steel tau dhau los ua tus xa khoom ntawm carbon steel kav nyob rau sab qaum teb Tuam Tshoj, paub txog nws cov kev pabcuam zoo, cov khoom zoo, thiab cov kev daws teeb meem.
Rau txhua qhov kev txiav txim, Botop ib txwm ua raws li lub tswv yim ntawm kev txhim khu kev qha zoo thiab cov nqi zoo, xaiv peb los muab koj cov khoom lag luam zoo steel yeeb nkab.
