SPCC yog thawj tus qauv Japanese (JIS) steel "feem ntau nrogtxias dov carbon steel ntawvthiab steel sawb "lub npe, ntau lub teb chaws los yog cov lag luam ncaj qha siv los qhia lawv tus kheej tsim cov hlau zoo sib xws (xws li Baosteel Q / BQB402 tus qauv muaj SPCC).
Nyob rau hauv Japanese JIS tus qauv, txias dov carbon ntawv muaj SPCC, SPCD, SPCE thiab lwm yam hom, ntawm cov tom kawg ob qhia tias stamping thiab sib sib zog nqus dej nrog txias dov carbon ntawv, uas yog sib npaug rau 08AL zoo carbon structural steel nyob rau hauv Tuam Tshoj 13237. txuj thiab 08AL sib sib zog nqus ntxuav steel hauv 5213 tus qauv.
SPCC txhais tau hais tias feem ntau siv cov ntawv txias txias, sib npaug rau Q195-Q215A hauv Suav teb, tsis txhob ua cov ntawv xeem stamping, yuav tsum xyuas kom meej tias qhov ntsuas tensile yog, tom qab tus naj npawb ntawm T rau SPCC-T lossis SPCT.
Qee qhov xwm txheej, SPCC tus lej yuav tsum qhia meej nws cov cai tswj xyuas qhov zoo thiab cov txheej txheem ua haujlwm saum npoo av. Ntawm lawv, qhov kev hloov kho zoo yog: A —— annealing xeev;S —— tus qauv zoo hloov kho;8 —— 1 / 8 nyuaj;4 —— 1 / 4 nyuaj;2 —— 1/2 nyuaj;1 — — hard.
Cov txheej txheem deg: D —— npub zoo dov;B —— ci ntsa iab zoo dov.Piv txwv li, SPCC-SD txhais tau hais tias tus qauv kev hloov kho zoo, npub zoo dov feem ntau txias dov cov ntawv carbon, SPCCT-SB txhais tau tias tus qauv kev hloov kho, ci ua haujlwm, txias dov carbon ntawv yuav tsum tau ua kom paub tseeb tias cov ntawv ua haujlwm zoo, thiab yog li ntawd.
