Qhov zoo ntawmJSC 270Dsteel rau cov khoom siv hauv tsev
Qhov elongation ntawm JSC270D yog ntau dua los yog sib npaug rau 34%, uas zoo dua li SPCC zoo tib yam (Ntau dua lossis sib npaug li 28%). Nws tuaj yeem tiv taus qhov nruab nrab- kev nyuaj stamping (xws li ncab thiab flanging), txo qhov kev pheej hmoo ntawm kev tawg, thiab qhov hardening Performance index (n nqi) ntau dua los yog sib npaug rau 0.18, kom ntseeg tau tias deformation uniformity; cov yas strain ratio (r tus nqi) ntau dua los yog sib npaug rau 1.4, uas yog tsim rau cov txheej txheem kos duab ntiav thiab sib sib zog nqus.
Cov txheej txheem txias dov ua kom lub ntsej muag du (Ra Tsawg dua lossis sib npaug ntawm 0.8μm), uas tuaj yeem raug txau ncaj qha thiab electroplated
Piv nrog rau qhov sib sib zog nqus nqus qib SPCD / DC04, tus nqi yog li 5% ~ 10% qis dua.
Daim ntawv thov tshwj xeeb ntawm JSC270D hauv kev lag luam khoom siv hauv tsev:
Cov tshuab ntxhua khaub ncaws: tswj vaj huam sib luag, lub thawv sab nrauv qhov cuab lub zog
Cov tub yees: tub rau khaub ncaws, qhov rooj ncej brackets
Lub tshuab cua txias: cov khoom siv plhaub (txhaj tshuaj-coated qhov chaw)
Cov khoom siv me me: microwave plhaub, nplej cooker puab lub lauj kaub txhawb nqa ncej
JSC270D steel qib yog dab tsi?
JSC270D steel yog txias- dov qis- carbon steel phaj ntawm Japanese Industrial Standard JIS G 3131. Nws qhov kev ua tau zoo yog nruab nrab ntawm qib zoo tib yam (xws li SPCC) thiab qib sib sib zog nqus (xws li SPCD). Nws yog cov khoom siv nruab nrab stamping siv nrog lub zog tensile ntawm 270MPa.
JSC270D steel sib npaug?
Cov qib ncaj qha sib npaug ntawm JSC270D steel yog SPCD (Japanese standard) thiab DC03 (European standard / national standard)
