Ntawm no yog cov lus qhia ntxaws ntxaws txogKub Rolled Steel Daim Hlau SM520B:

Cov Lus Qhia Yooj Yim

Zaj piav

Sm520b yog kub-rolled tsawg-alloy high-zog hlau phaj teev nyob rau hauv Japanese muaj kev lag luam qauv (JIS G3106). Nws yog dav siv nyob rau hauv cov ntawv thov txheej txheej uas yuav tsum tau muaj lub zog siab thiab cov kws kho zoo. Qhov "SM" kev tsim qauv sawv rau "qauv qauv hlau rau cov kev pabcuam kub-kub thiab" thiab "520" hais txog nws lub zog tsawg kawg ntawm 520 MPa.

Naming convention

Sw: Tus qauv hlau tsim rau kev tsim kho dav dav thiab engineering.

520: Yam tsawg kawg tensile lub zog (520 mpa).

B: Qhia cov hlau cov qib zoo thiab cov khoom lag luam (muaj feem xyuam rau kev cuam tshuam tsis kam thiab tshuaj lom neeg).

Tshuaj lom neeg muaj pes tsawg leeg (muaj nuj nqis)

Lub ntsiab	Cov ntsiab lus ntau (%)	Lub luag hauj lwm
Carbon (c)	Tsawg dua los yog sib npaug rau 0. 20	Sib npaug lub zog thiab weldability; Txo cov pa hluav taws xob txhim kho ductility.
Manganese (mn)	1.00–1.60	Txhim kho lub zog thiab hardness; txhim kho cov neeg muaj kev nyuaj.
Silicon (si)	0.15–0.55	Ntxiv dag zog rau lub matrix; txhim kho tiv thaiv oxidation.
Phosphorus (p)	Tsawg dua li lossis sib npaug rau 0. 035	Teeb meem kev teeb meem; 严控 Txo kom tsawg brittleness.
Sulphur (s)	Tsawg dua li lossis sib npaug rau 0. 035	Teeb meem kev teeb meem; 严控 txhawm rau txhim kho kev sib zog thiab weldability.
Alloying Ntsiab(yog tias ntxiv)	Tsawg dua los yog sib npaug rau 0. 15 (piv txwv li, v, nb, ti)	Refine nplej, txhim kho lub zog thiab tawv (muaj ntau hauv cov qib niaj hnub).

 

Tsab ntawv: Qhov muaj pes tsawg leeg yuav txawv ntawm cov chaw tsim khoom thiab ua raws li JIS cov qauv.

Cov Khoom Siv Neeg Kho Tshuab

Ntiag tug	Qhov yuav tsum tau (JIS G3106)
Paib Zog (₀₀.₂)	Ntau dua los yog sib npaug rau 355 mpa (rau thickness tsawg dua los yog sib npaug rau 16 hli)
Lub zog tensile	520-685 mpa
Elongation (₅₅)	Ntau dua los yog sib npaug rau 19% (rau thickness tsawg dua los yog sib npaug rau 16 hli)
Cuam tshuam kev xeem (Charpy V)	Ntau dua los yog sib luag rau 27 j ntawm 0 degree (rau qib b)

 

Tsab ntawv: Cov yam ntxwv zoo li yuav txawv nrog phaj tuab. Thicker daim phiaj feem ntau muaj tsawg dua qis zog zog zog.

Txheej txheem tsim khoom: Kub Rolling

Tso kev sov: Hlau bilts yog rhuab rau 1,100-1,300 degree kom lawv malleable.

Dov: Dhau los ntawm Rolling mills kom txo qis tuab thiab ua cov phaj. Kub Rolling txhim kho cov nplej ntws thiab cov neeg kho tshuab sib xyaw.

Cua txias: Huab cua txias rau chav sov, ua rau muaj ferritic-pearlitic microstructure nrog ntsuas ntsuas thiab ductility.
