Khoom Description
Cov khoom siv ntawm Q235B steel hauv Suav teb zoo ib yam li cov SS400 steel hauv Nyiv. JIS Steel Qib SS400 yog qhov sib npaug rau Q235B steel hauv Suav teb, tab sis muaj qee qhov sib txawv ntawm cov ntsuas tshwj xeeb. Steel qib SS400 sib npaug Q235B xav tau cov ntsiab lus ntawm C, Si, Mn, S, P thiab lwm yam, tab sis steel qib SS400 tsuas yog xav tau S, P tsawg dua 0.050. Cia peb tshawb xyuas Steel qib SS400 sib npaug Q235B thiab SS400 steel qhov sib txawv hauv qab no:
Steel qib SS400 sib npaug Q235B tshuaj muaj pes tsawg leeg:
| QIB | C | Mn | P | S | Si |
| Q235B | 0.12-0.20 | 0.30-0.70 | Tsawg dua lossis sib npaug li 0.045 | Tsawg dua lossis sib npaug li 0.045 | Tsawg dua los yog sib npaug li 0.30 |
| SIB 400 | - | - | Tsawg dua lossis sib npaug li 0.050 | Tsawg dua lossis sib npaug li 0.050 | - |
Hlau qib SS400 sib npaug Q235B cov khoom siv tshuab:
| QIB | YIELD HEEV | TENSILE HEEV | EXTENSION |
| MPA | MPA | % | |
| Q235B | Ntau dua lossis sib npaug rau 235 | 375~460 | Ntau dua lossis sib npaug li 21 |
| SIB 400 | Ntau dua lossis sib npaug li 205 | 400~510 | Ntau dua lossis sib npaug li 17 |
Qhov taw tes tawm ntawm steel qib SS400 sib npaug Q235B yog ntau dua 235 MPa, thaum steel qib SS400 tawm taw tes yog 205MPa. SS400 steel txhais tau tias steel nrog lub zog tensile siab dua 400 MPa rau cov qauv dav dav. Steel qib SS400 sib npaug Q235B txhais tau hais tias cov pa roj carbon zoo tib yam steel nrog cov ntsiab lus tawm los ntau dua 235MPa. Tus naj npawb ntawm SS400 steel yog JIS G3101. Tus qauv tooj hlau SS400 sib npaug Q235B yog GB / T 700.
Vim li cas cov khoom siv hlau hauv Channel?
Hlau yog suav tias yog cov hlau zoo tshaj plaws los siv thaum ua cov hlau txuas vim nws cov khoom siv kho tshuab.
Hardness: Lub peev xwm los zam qhov deg indentation (localized yas deformation) thiab khawb yog hu ua hardness. Hardness tuaj yeem qhia txog kev khawb tsis kam, puas ua haujlwm, indentation kuj, thiab txawm tias shaping lossis localized yas deformation kuj; yog li ntawd, nws yog kab tias cov khoom siv tsis zoo tshaj plaws. Los ntawm ib qho engineering nam, hardness yog qhov tseem ceeb vim hais tias nws ua rau kom tsis kam hnav los ntawm kev sib txhuam los yog yaig los ntawm chav, roj, thiab dej.
Toughness: Lub peev xwm nqus tau lub zog tsis muaj kev tawg lossis tawg. Toughness kuj yog lub peev xwm ntawm ib yam khoom los tiv thaiv tawg thaum strained. Qhov txawv ntawm toughness thiab hardness yog tias cov khoom uas deforms ntau yam tsis muaj kev tawg tuaj yeem hu ua tawv heev tab sis tsis tawv.
