A179 steel yeeb nkab sab nraud txoj kab uas hla thiab ovality yuav tsum tau kuaj nrog lub caliper, vernier caliper lossis lub nplhaib ntsuas los txiav txim siab qhov siab tshaj plaws thiab qhov tsawg kawg nkaus.
A179 steel yeeb nkab ntev yog kuaj nrog ib daim kab xev ntsuas, nrog rau kev ntsuas phau ntawv thiab tsis siv neeg qhov ntev.
A179M steel yeeb nkab curvature soj ntsuam siv ib tug pas ntsuas, ib theem thiab ib tug feeler gauge ntsuas qhov curvature ib 'meter' thiab tag nrho ntev.
A179 steel yeeb nkab kawg lub ntsej muag zawj lub kaum sab xis thiab blunt ntug yuav tsum tau kuaj xyuas nrog lub square thiab pallet.
A179M Carbon steel yeeb nkab nto zoo soj ntsuam
100% kev tshuaj xyuas qhov muag pom tau ua tiav los xyuas kom meej tias qhov chaw ntawm A179 steel yeeb nkab tsis muaj qhov tsis xws luag xws li tawg, folds, dov folds, delamination, hairline thiab caws pliav.

Kev tshuaj xyuas kev ua haujlwm ntawm A179 Heat Exchanger Tubes
Kev ntsuas tensile ntawm A179M steel yeeb nkab yuav tsum ntsuas kev ntxhov siab thiab deformation los txiav txim siab cov khoom siv zog thiab plasticity Performance index.
Qhov kev ntsuam xyuas cuam tshuam yuav tsum tau ua los ntawm CVN, notch C-type, V-type test, thiab ntsuas kev ua haujlwm thiab J tus nqi.
Qhov kev ntsuas hardness yuav tsum ntsuas Brinell hardness, Rockwell hardness thiab Vickers hardness.
Kev ntsuas hydraulic yuav tsum tau ua los ntawm kev ntsuas siab thiab lub sijhawm ntsuas kev ruaj ntseg.
Cov txheej txheem kev tshuaj xyuas ntawm A179M Seamless Carbon Cold Drawn Steel Tubes
Kev kuaj flattening yuav tsum kuaj xyuas qhov deformation ntawm cov qauv ncig.
Lub nplhaib rub kev sim thiab kev nthuav dav thiab kev ntsuas curling yuav tsum kuaj xyuas qhov deformation ntawm cov yeeb nkab steel.
Qhov kev sim khoov tuaj yeem hloov qhov kev sim flattening, tshwj xeeb tshaj yog rau cov kav dej loj.
Metallographic tsom xam ntawm A179 steel yeeb nkab
Kev tshuaj xyuas lub zog siab (microanalysis) yuav tsum kuaj xyuas cov khoom tsis yog hlau thiab cov nplej loj.
Kev ntsuam xyuas macroscopic (kev tshuaj ntsuam macro) yuav tsum siv cov kua qaub etching test, sulfur print test thiab pyramidal hairline test txhawm rau txheeb xyuas cov qauv qis thiab qhov tsis xws ntawm cov kav hlau.
