ST52/45#/Q345/16Mn seamless steel kav

Nthuav Qhia:

Seamless steel kav yog ua los ntawm ib puag ncig steel perforated. Cov kav hlau uas tsis muaj welds rau saum npoo yog hu ua seamless steel kav. Raws li txoj kev tsim, seamless steel kav yuav muab faib ua kub dov seamless steel kav, txias dov seamless steel kav, txias-draw seamless steel kav, extruded seamless steel kav, jacked kav, thiab lwm yam. zoo li, seamless steel kav muab faib ua ob hom: puag ncig thiab tshwj xeeb-puab. Cov kav dej tshwj xeeb muaj ntau yam duab xws li square, oval, daim duab peb sab, hexagon, melon-puab, lub hnub qub, thiab finned kav. Qhov siab tshaj plaws txoj kab uas hla yog 900 hli thiab qhov tsawg kawg nkaus txoj kab uas hla yog 4 hli. Raws li kev siv sib txawv, muaj tuab-walled seamless steel kav thiab nyias-walled seamless steel kav. Seamless steel kav feem ntau yog siv los ua roj av geological drilling kav, tawg kav rau petrochemical kev lag luam, boiler kav, bearing kav, thiab high-precision steel yeeb nkab rau tsheb, tsheb laij teb, thiab aviation.

Q345 steel yeeb nkab, tseem hu ua 16Mn, 16Mn seamless steel yeeb nkab yog cov hlau tsis tshua muaj hlau. Nws yog feem ntau siv steel rau boilers thiab siab hlab ntsha. Nws yog kub dov los yog normalized. Nws yog cov hlau tsis tshua muaj hlau nrog cov ntsiab lus qis Mn. Qhov kev ua tau zoo zoo ib yam li 20G (412-540), lub zog tensile zog me ntsis (450-655), thiab elongation yog 19-21%, uas yog phem tshaj 20G uas yog ntau tshaj 24%.

16Mn seamless steel yeeb nkab yog lub phaj tshwj xeeb rau cov hlab ntsha siab nrog lub zog ntawm 340MPa. Nws muaj cov cuab yeej zoo txhua yam thiab cov txheej txheem ua tau zoo. Cov ntsiab lus phosphorus thiab sulfur yog me ntsis qis dua li qub 16Mn hlau. Ntxiv nrog rau lub zog tensile thiab elongation yuav tsum siab dua li 16Mn steel, kev cuam tshuam toughness kuj yuav tsum tau ua kom ntseeg tau. Nws yog feem ntau siv thiab dav siv tshwj xeeb steel phaj rau siab qhov rais hauv kuv lub teb chaws.

45 # steel: nruab nrab cov ntsiab lus carbon yog 0.42-0.50%, nruab nrab silicon ntsiab lus yog 0.17-0.37%, nruab nrab manganese cov ntsiab lus yog 0.50-0.80%, nruab nrab cov ntsiab lus sulfur <= 0.035%, nruab nrab phosphorus ntsiab lus <= 0.035%, nruab nrab chromium ntsiab lus <= 0.25%, nruab nrab nickel cov ntsiab lus <= 0.2545 steel

hauj lwm:

Seamless kav yog tsim los ntawm round steel billets uas yog xuas nrig ntaus los ntawm qhov chaw los tsim hollow hlab uas ces dov los yog extruded thiab kos rau loj.
