Q355 S355 Chitoliro Chachikulu ndi Chamakona Chitsulo Mtengo Pa Chidutswa

S355 ndi Q355 zonse ndi mayina a chitsulo chomangidwa, koma zimachokera ku miyezo yosiyana ndipo zimakhala ndi kusiyana pang'ono muzofotokozera ndi momwe zimagwiritsidwira ntchito.

Chitsulo cha S355
Muyezo: EN 10025-2 (European Standard)
Kalasi: S355
Kufotokozera: S355 ndi chitsulo cholimba kwambiri, chopanda aloyi ambiri chomwe chili ndi mphamvu yocheperako ya 355 MPa. Chimagwiritsidwa ntchito kwambiri pomanga ndi kugwiritsa ntchito kapangidwe kake chifukwa cha kusinthasintha kwake bwino komanso makina ake ogwirira ntchito.
Ma Subgrade Ofala:

S355JR: Chitsulo chopangidwa ndi chitsulo chokhala ndi mphamvu yocheperako ya 355 MPa ndi mphamvu yogwira ya 27J kutentha kwa chipinda.
S355J0: Mphamvu yochepa kwambiri ya 27J pa 0°C.
S355J2: Mphamvu yochepa kwambiri ya 27J pa -20°C.

Chitsulo cha Q355
Muyezo: GB/T 1591 (Muyezo Wachi China)
Giredi: Q355
Kufotokozera: Q355 ndi chitsulo cholimba kwambiri chomwe chili ndi mphamvu yocheperako ya 355 MPa, yofanana ndi S355. "Q" imayimira "Qu" (gawo lotsika), ndipo "355" imatanthauza mphamvu yocheperako ya chitsulo mu MPa.
Ma Subgrade Ofala:

Q355B: Mphamvu yochepa kwambiri ya 27J pa 20°C.
Q355C: Mphamvu yochepa kwambiri ya 27J pa 0°C.
Q355D: Mphamvu yochepa kwambiri ya 27J pa -20°C.
