SS400 inzira yekumaka yemidziyo yesimbi yeJapan uye chiyero chekutonga.
Simbi dzezvimiro mumiyero yekunze dzinowanzo kupatsanurwa maererano nekusimba kwesimba, senge SS400 (yakanyorwa seyakadaro muJapan), uko 400 inomiririra σ Ukoshi hushoma hwe b ndeye 400MP. Ultra yakakwirira simba simbi inoreva σ Simbi isingasviki 1373 Mpa.
1. Zvinoreva zvakasiyana
SS400: SS400 inzira yekumaka yemidziyo yesimbi muJapan uye chiyero chekutonga, chakaenzana neQ235 simbi muChina.
Q235: Q235 yakajairwa kabhoni dhizaini simbi inonzi zvakare A3 simbi. Ordinary carbon structural steel plain plate imhando yesimbi.
2. Mapoinzi egoho akasiyana
Iyo goho poindi yeQ235 yakakura kupfuura 235 MPa, nepo iyo yeSS400 iri 245 MPa.
3. Nhamba dzemhando dzakasiyana
Nhamba yakajairwa yeQ235 ndeye GB/T700. Nhamba yakajairwa yeSS400 iJIS G3101.
4. Simba rakasiyana
SS400: Masimbi emuumbirwo mumiyero yekunze anowanzo kupatsanurwa maererano nekusimba kwesimba, senge SS400 (yakanyorwa seyakadaro muJapan), umo 400 inoreva σ iyo shoma kukosha kwe b ndeye 400MPa. Ultra-yakakwirira simba simbi inoreva σ B Simbi isingasviki 1373 Mpa.
Q235: Q inomiririra muganho wegoho wechinhu ichi. Inotevera 235 inoreva kukosha kwegoho rechinhu ichi, chingangoita 235MPa. Iko kukosha kwegoho kuchadzikira nekuwedzera kwekukora kwezvinhu. Nekuda kwepakati kabhoni yemukati, iyo yakazara zvivakwa zvakanaka, uye simba, plastiki uye welding zvivakwa zvinonyatsoenderana.
5. Kuenzanisa kwemakemikari ekugadzirisa pakati peQ235 neSS400
Q235B kabhoni C: hapana kupfuura 0.18
Q235B Mn: 0.35-0.80
Q235B silicon Si: hapana kupfuura 0.3

Q235B phosphorus P: hapana kupfuura 0.04
SS400 sarufa S: hapana kupfuura 0.05
SS400 Phosphorus P: hapana kupfuura 0.05
6. Kufananidzwa kwema mechanical properties pakati peQ235 neSS400
Q235 goho simba: kwete pasi pe185.
Q235 tensile simba: 375-500
Q235 kureba: kwete pasi pe21
SS400 goho simba: kwete pasi pe215.
SS400 tensile simba: 400-510
SS400 kureba: kwete pasi pe17
