A53 seamless steel yeeb nkab yog ib yam khoom ntawm American standard steel yeeb nkab, nyob rau hauv uas a53-a yog sib npaug rau domestic 10 # steel, a53-b yog sib npaug rau domestic 20 # steel, thiab a53-f yog sib npaug rau domestic Q235 khoom.
Cov hlau tsis muaj hlau yog suav tias yog cov qauv hlau zoo tib yam, uas yog tshwj xeeb los ntawm lub zog tensile thiab qhov taw tes tawm.
16Mn yog cov hlau tsis tshua muaj siab-lub zog steel: cov ntsiab lus carbon yog 0.1% - 0.25%, thiab cov ntsiab lus tseem ceeb ntawm manganese, silicon, vanadium, niobium thiab titanium ntxiv; Nws tag nrho cov ntsiab lus alloy yog tsawg dua 3%.
35CrMo yog tus naj npawb ntawm cov qauv hlau alloy (alloy quenched thiab tempered steel), uas yog siv los tsim cov khoom tseem ceeb hauv ntau lub tshuab muaj kev cuam tshuam, khoov thiab torsion thiab siab load.
30CrMo alloy steel yeeb nkab muaj cov ntsiab lus carbon ntawm 0.26 ~ 0.34, silicon ntsiab lus ntawm 0.17 ~ 0.37, manganese cov ntsiab lus ntawm 0.40 ~ 0.70, molybdenum cov ntsiab lus ntawm 0.15 ~ 0.25, chromium ntsiab lus ntawm 0.80 ~ 1.10.
Cov qib steel ntawm European txheem seamless steel kav yog P195, p235, p265, p195gh, p235gh, P265GH, 13crmo4-5 thiab 10crmo9-10.
Daim ntawv thov teb ntawm 12Cr1MoVG alloy yeeb nkab tau nthuav dav los muab qhov chaw dav rau kev txhim kho kev lag luam.
Lub hom phiaj ntawm 42CrMo seamless steel yeeb nkab: cov hlau tshwj xeeb rau choj yog "42CrMo", tshwj xeeb hlau rau tsheb girder yog "42CrMo", thiab cov hlau tshwj xeeb rau lub nkoj siab yog "42CrMo".
