Kev piav qhia ntawm SPCC cov qib hlau dov txias

1 lub npe txhais
SPCCthawj zaug yog tus qauv Nyiv Pooj (JIS) "kev siv dav dav ntawmCov ntawv hlau carbon txias dovthiab strip" hlau lub npe, tam sim no ntau lub tebchaws lossis cov lag luam siv ncaj qha los qhia lawv tus kheej cov hlau zoo sib xws. Nco ntsoov: cov qib zoo sib xws yog SPCD (cov hlau carbon txias dov thiab strip rau stamping), SPCE (cov hlau carbon txias dov thiab strip rau kev kos duab tob), SPCCK \ SPCCCE, thiab lwm yam (cov hlau tshwj xeeb rau cov TV teeb tsa), SPCC4D \ SPCC8D, thiab lwm yam (cov hlau tawv, siv rau cov log tsheb kauj vab, thiab lwm yam), feem, rau ntau lub sijhawm sib txawv.

2 Cheebtsam
Cov hlau Nyiv (JIS series) hauv qib ntawm cov hlau qauv feem ntau muaj peb ntu ntawm thawj ntu ntawm cov khoom siv, xws li: S (Hlau) uas yog hlau, F (Ferrum) uas yog hlau; ntu thib ob ntawm ntau yam duab, hom, thiab kev siv, xws li P (Phaj) uas yog phaj, T (Tub) uas yog raj, K (Kogu) uas yog cuab yeej; ntu thib peb ntawm cov yam ntxwv ntawm tus lej, feem ntau yog qhov tsawg kawg nkaus tensile zog. Feem ntau yog qhov tsawg kawg nkaus tensile zog. Xws li: SS400 - thawj S hais tias hlau (Hlau), qhov thib ob S hais tias "qauv" (Qauv), 400 rau qhov qis tshaj plaws ntawm tensile zog ntawm 400MPa, lub zog tensile tag nrho ntawm 400MPa rau cov hlau qauv dav dav nrog lub zog tensile ntawm 400MPa.

Ntxiv: SPCC - cov hlau carbon txias dov thiab daim kab xev rau kev siv dav dav, sib npaug rau Suav teb Q195-215A qib. Tsab ntawv thib peb C yog lub npe luv rau txias txias. Yuav tsum xyuas kom meej tias qhov kev sim tensile, thaum kawg ntawm qib ntxiv T rau SPCCT.

3 kev faib tawm hlau
Nyiv PoojCov hlau phaj carbon txias dovCov qib siv tau: SPCC, SPCD, SPCE cov cim: S - hlau (Hlau), P - phaj (Phaj), C - dov txias (txias), plaub C - feem ntau (feem ntau), D - stamping qib (Kos), E - kos duab tob (Elongation)

Kev kho cua sov: A-Annealed, S-Annealed + Flat, 8-(1/8) tawv, 4-(1/4) tawv, 2-(1/2) tawv, 1-nyuaj.

Qib kev ua tau zoo ntawm kev kos duab: ZF- rau kev xuas nrig qhov chaw uas muaj kev kos duab nyuaj tshaj plaws, HF- rau kev xuas nrig qhov chaw uas muaj kev kos duab nyuaj heev, F- rau kev xuas nrig qhov chaw uas muaj kev kos duab nyuaj.

Qhov Xwm Txheej Tiav Ntawm Qhov Chaw: D - Ntsoov (yob ua tiav los ntawm lub tshuab sib tsoo thiab tom qab ntawd tua peened), B - Qhov Chaw Ci (yob ua tiav los ntawm lub tshuab sib tsoo).

Qhov zoo ntawm qhov chaw: FC-qhov chaw tiav siab heev, FB-qhov chaw tiav siab dua. Xwm txheej, xwm txheej tiav ntawm qhov chaw, qhov zoo ntawm qhov chaw, qib kos duab (rau SPCE xwb), cov lus qhia tshwj xeeb thiab qhov loj ntawm cov khoom, qhov tseeb ntawm cov ntaub ntawv (tuab thiab/lossis dav, ntev, tsis sib xws).
