DIN 1629 ST44 Carbon Seamless Steel Yeeb Nkab
DIN 1629 structural kavmuab los ntawm GNEE raug tshuaj xyuas ntau zaus los xyuas kom meej qhov zoo. Koj tuaj yeem tshawb nrhiav txhua qhov loj thiab qib ntawm steel seamless kav los sib piv cov nqi.
DIN 1629 ST44 seamless carbon steel yeeb nkab yog cov yeeb nkab uas tsis tshua muaj carbon steel nrog cov ntsiab lus siab tshaj plaws ntawm 0.21%, uas yooj yim rau kev tsim thiab vuam. Nws yog tsim rau ntau hom vuam xws li roj fusion vuam, arc vuam, nyem taub qab vuam, voltage vuam thiab roj siab vuam. Kev ua haujlwm kub ntawm DIN 1629 ST44 carbon steel yeeb nkab yog txwv rau qis dua 300 degree.
DIN 1629 ST44 seamless yeeb nkab tsis tsuas yog muaj kev sib txuas zoo, tab sis kuj muaj zog tensile siab thiab lub zog, uas yuav tsum tau rau cov khoom siv. Yog li ntawd, DIN 1629 ST44 steel seamless yeeb nkab yog tsuas yog siv nyob rau hauv cov tshuaj nroj tsuag, ships, pipeline siv thiab rau kev siv tshuab engineering.
