S355 ndi Q355 onse ndi mayina a zitsulo zomangika, koma amachokera ku miyezo yosiyana ndipo amasiyana mosiyana ndi momwe amagwiritsira ntchito.
Chithunzi cha S355
Muyezo: EN 10025-2 (European Standard)
Gulu: S355
Kufotokozera: S355 ndi chitsulo champhamvu kwambiri, chochepa chachitsulo chokhala ndi mphamvu zochepa zokolola za 355 MPa. Amagwiritsidwa ntchito kwambiri pomanga ndi zomangamanga chifukwa cha weldability wake wabwino komanso machinability.
Common Subgrades:
S355JR: Chitsulo chokhazikika chokhala ndi mphamvu zochepa zokolola za 355 MPa ndi mphamvu ya 27J kutentha kwapakati.
S355J0: Mphamvu zocheperako za 27J pa 0°C.
S355J2: Mphamvu zocheperako za 27J pa -20°C.
Q355 Zitsulo
Muyezo: GB/T 1591 (Chinese Standard)
Gawo: Q355
Kufotokozera: Q355 ndi chitsulo cholimba kwambiri chokhala ndi mphamvu zochepa zokolola za 355 MPa, zofanana ndi S355. "Q" imayimira "Qu" (malo okolola), ndipo "355" amatanthauza kuchepa kwa mphamvu zokolola mu MPa.
Common Subgrades:
Q355B: Mphamvu zocheperako za 27J pa 20°C.
Q355C: Mphamvu zosachepera 27J pa 0°C.
Q355D: Mphamvu zocheperako za 27J pa -20°C.

Kuwongolera Kwabwino Kwambiri:
1) Panthawi komanso pambuyo popanga, antchito 4 a QC omwe ali ndi zaka zopitilira 5 amayendera zinthu mwachisawawa.
2) Laborator yovomerezeka yadziko lonse yokhala ndi ziphaso za CNAS
3) Kuyamikiridwa kovomerezeka kuchokera kwa anthu ena osankhidwa / olipidwa ndi wogula, monga SGS, BV.
4) Kuvomerezedwa ndi Malaysia, Indonesia, Singapore, Philippines, Australia, Peru ndi UK. Tili ndi UL / FM, ISO9001/18001, ziphaso za FPC
Kulongedza ndi Kutumiza:
Tsatanetsatane Wolongedza : mu mitolo ya hexagonal yoyenera kunyanja yodzaza ndi zingwe zachitsulo, Zokhala ndi ma nayiloni awiri pamitolo iliyonse.
Zambiri Zotumizira : Kutengera QTY, nthawi zambiri mwezi umodzi.
Zambiri zaife:
Tianjin Youfa anakhazikitsidwa pa July 1, 2000. Pali kwathunthu za 8000 antchito, 9 mafakitale, 179 zitsulo mizere kupanga chitoliro, 3 zasayansi dziko zovomerezeka, ndi 1 Tianjin zovomerezeka boma luso pakati bizinesi.
31 lalikulu ndi rectangular zitsulo mizere kupanga chitoliro
