Q: Menene bambanci tsakanin S275J2H da S275J0H?

A:Dukansu maki suna da matakin ƙarfi iri ɗaya (275 MPa na amfanin gona), amma sun bambanta a yanayin zafi na taurin tasiri: Ana gwada S275J2H a -20°C (27J), yayin da ake gwada S275J0H a 0°C (27J). Ana fifita S275J2H a yanayin sanyi.

Q: Menene bambanci tsakanin EN 10210 da EN 10219?

A:EN 10210 ya ƙunshi sassan gine-gine masu zurfi da aka gama da zafi (wanda aka yi kuma aka gama a yanayin zafi mai girma), yayin da EN 10219 ya ƙunshi sassan da aka yi da sanyi (wanda aka yi a yanayin zafi na ɗaki). Sassan da aka gama da zafi gabaɗaya suna ba da ƙarancin damuwa na ciki, mafi kyawun kwanciyar hankali, da kuma ƙarfin ƙarancin zafin jiki.

Q: Shin S275J2H ya dace da walda?

A:Eh. Tare da ƙarancin CEV (≤ 0.41%), S275J2H yana nuna kyakkyawan ƙarfin walda. Ba a buƙatar dumamawa kafin lokaci ga kauri ƙasa da 20mm. Ga sassa masu kauri, ana amfani da hanyoyin walda na yau da kullun.

Q: Menene mafi ƙarancin zafin ƙira na S275J2H?

A:Dangane da EN 1993 (Eurocode 3), ana iya amfani da S275J2H ƙasa zuwa -20°C tare da tabbatar da gwajin tasirin Charpy a -20°C (mafi ƙarancin 27J).

Q: Menene matsakaicin zafin sabis na S275J2H?

A:Tsarin aiki yawanci yana amfani da S275J2H har zuwa kimanin 350-400°C. Don ci gaba da aiki mai zafi, duba jagorar ƙira ta EN 1993.

Q: Za a iya samar da takardar shaidar EN 10204 Type 3.2 ta S275J2H?

A:Eh. Womic Steel tana ba wa S275J2H takaddun shaida na Type 3.2 waɗanda hukumomin da EU ta amince da su suka tabbatar, ciki har da TÜV, BV, SGS, da LR.

Q: Menene lokacin jagora na yau da kullun don bututun S275J2H mara sumul?

A:Lokacin isar da kaya na yau da kullun shine kwanaki 25-35 ga girma da adadi na gama gari. Manyan oda ko girma na musamman na iya buƙatar kwanaki 40-50.
