ASTM A1085 yog dab tsi?
Cov qauv no suav nrog txias- tsim welded carbonsteel hollow structural seem (HSS) rau welded lossis bolted siv.
Cov duab no yog siv rau hauv tab sis tsis txwv rau cov hauv qab nodaim ntawv thov: cov tsev, txuas hniav, yees, cranes, kos npe txhawb thiab ncej, tawm ntawm- ntug dej hiav txwv tsim thiab drilling platforms, yob- hla cov qauv tiv thaiv (ROPS), ntog khoom tiv thaiv cov qauv (FOPS), thiab kev lom zem caij tsheb.
Tshuaj muaj pes tsawg leeg
Kev Ntsuas Kub
Qhov siab tshaj plaws tso cai carbon sib npaug yuav tsum yog 0.45%.
Cov pa roj carbon sib npaug yuav tsum suav nrog cov qauv hauv qab no:CE=C + Mn / 6 + (Cr+Mo+V) / 5 + (Ni+Cu) / 15
Kev tshuaj xyuas khoom
Yog tias kev tshuaj xyuas cov khoom lag luam raug tsim, lawv yuav tsum tau ua los ntawm cov qauv kuaj coj los ntawm ob qhov ntev ntawm HSS los ntawm txhua qhov ntau ntawm 500 qhov ntev, lossis feem ntawm qhov ntawd, lossis ob daim ntawm lub tiaj tus -rolledstock los ntawm txhua qhov sib npaug ntawm cov khoom tiaj tus -rolled stock.
