SS400 ndi njira yolembera zida zachitsulo zaku Japan komanso muyezo woweruza.
Zitsulo zamapangidwe mumiyezo yakunja nthawi zambiri zimayikidwa molingana ndi mphamvu zolimba, monga SS400 (yomwe ili ku Japan), pomwe 400 imayimira σ Mtengo wocheperako wa b ndi 400MP. Chitsulo champhamvu kwambiri chimatanthawuza σ Chitsulo chosachepera 1373 Mpa.
1. Matanthauzo osiyanasiyana
SS400: SS400 ndi njira yolembera zida zachitsulo ku Japan ndi muyezo woweruza, wofanana ndi chitsulo cha Q235 ku China.
Q235: Q235 wamba mpweya structural zitsulo amatchedwanso A3 zitsulo. Carbon structural steel plain plate ndi mtundu wazitsulo zachitsulo.
2. Zokolola zosiyanasiyana
Zokolola za Q235 ndizokulirapo kuposa 235 MPa, pomwe za SS400 ndi 245 MPa.
3. Ziwerengero zosiyana siyana
Nambala yokhazikika ya Q235 ndi GB/T700. Nambala yokhazikika ya SS400 ndi JIS G3101.
4. Mphamvu zosiyana
SS400: Zitsulo zamapangidwe mumiyezo yakunja nthawi zambiri zimagawidwa molingana ndi mphamvu zolimba, monga SS400 (yomwe ili ku Japan), pomwe 400 imatanthauza σ mtengo wocheperako wa b ndi 400MPa. Chitsulo champhamvu kwambiri chimatanthawuza σ B Chitsulo chosachepera 1373 Mpa.
Q235: Q imayimira malire azinthu izi. 235 yotsatirayi ikunena za mtengo wazinthuzi, womwe uli pafupifupi 235MPa. Mtengo wa zokolola udzachepa ndi kuwonjezeka kwa makulidwe a zinthu. Chifukwa chokhala ndi mpweya wocheperako, zinthu zonse ndi zabwino, ndipo mphamvu, pulasitiki ndi kuwotcherera zimagwirizana bwino.
5. Kuyerekezera kwa mankhwala pakati pa Q235 ndi SS400
Q235B carbon C: osapitirira 0.18
Q235B Mn: 0.35-0.80
Q235B silicon Si: osapitirira 0.3

Q235B phosphorous P: osapitirira 0.04
SS400 sulfure S: osapitirira 0.05
SS400 Phosphorus P: osapitirira 0.05
6. Kuyerekeza kwazinthu zamakina pakati pa Q235 ndi SS400
Q235 zokolola mphamvu: osachepera 185.
Q235 mphamvu yamphamvu: 375-500
Q235 elongation: osachepera 21
SS400 zokolola mphamvu: zosachepera 215.
SS400 mphamvu yamphamvu: 400-510
Kutalika kwa SS400: osachepera 17
