10 # Ipayipi lensimbi engenamthungo

Incazelo emfushane:

Ukucaciswa kokukhiqiza:

Ububanzi bangaphandle bepayipi lensimbi 20-426

Ipayipi lensimbi odongeni ukujiya 20-426

Ukwakheka kwamakhemikhali:

● No. 10 ukwakheka kwamakhemikhali kwepayipi lensimbi engenamthungo:

I-Carbon C: 0.07~0.14″ i-silicon Si: 0.17 ~ 0.37 Manganese Mn: 0.35 ~ 0.65 Sulfur S: ≤0.04 Phosphorus P: ≤0.35 chromium Cr: ≤0.15 I-Nickel0 ≤0 I-5.

Impahla yemishini:

Izinto zikagesi zepayipi lensimbi engenamthungo No. 10:Amandla e-Tensile σb (MPa) : ≥410(42) Amandla okukhiqiza σs (MPa) : ≥245(25) ubude δ5 (%) : ≥25 ukushwabana kwengxenye (%) : ≥5 , ubulukhuni: okungashiswanga,≤156HB, usayizi wesampula: 25mm.

Ikhwalithi ephezulu yensimbi ye-carbon structural:

No. 10 ipayipi lensimbi engenamthungo aliqukethe ezinye izakhi zengxubevange (ngaphandle kwezakhi ezisele) ngaphandle kwesici se-carbon (C) kanye nenani elithile le-silicon (Si) le-deoxidation (ngokuvamile angabi ngaphezu kuka-0.40%), i-manganese (Mn) (ngokujwayelekile ayi ngaphezu kuka-0.80%, kufika ku-1.20%) izakhi ze-alloy.

Insimbi enjalo kufanele ibe nakho kokubili ukwakheka kwamakhemikhali kanye nezakhiwo zemishini.Okuqukethwe yi-sulphur (S) ne-phosphorus (P) ngokuvamile kulawulwa ngaphansi kuka-0.035%.Uma ilawulwa ngaphansi kwe-0.030%, ibizwa ngokuthi insimbi yekhwalithi ephezulu, futhi "A" kufanele ingezwe ngemuva kwebanga, njenge-20A;Uma i-P ilawulwa ngaphansi kuka-0.025% futhi i-S ilawulwa ngaphansi kuka-0.020%, ibizwa ngokuthi insimbi yekhwalithi ephezulu, futhi "E" kufanele yengezwe ngemva kwebanga ukuze kuboniswe umehluko.Kwezinye izakhi ze-alloying ezisele ezilethwe ensimbi ngezinto zokusetshenziswa, njenge-chromium (Cr), i-nickel (Ni), ithusi (Cu), njll., okuqukethwe kwe-Cr≤0.25%, Ni≤0.30%, Cu≤0.25%.Ezinye izinhlobo ze-manganese (Mn) okuqukethwe kufika ku-1.40%, ezaziwa ngensimbi ye-manganese.

Inombolo 10 yepayipi lensimbi engenamthungo ifomula yokubala isisindo :[(ububanzi bangaphandle - ukujiya kodonga)* ukujiya kodonga]*0.02466=kg/ m (isisindo imitha)
