Zipangizo za S275J0H zimadziwika ndi mphamvu yotsika ya 275 MPa pa makulidwe osapitirira 16 mm; mphamvu yake yotsika ya kugunda ndi osachepera 27 J pa 0℃.
S275J0H ndi ya mtundu wa chitsulo cha kaboni, nambala ya chitsulo1.0149, yomwe ili ndi makhalidwe abwino omangira ndi kukonza, makamaka omwe amagwiritsidwa ntchito pomanga nyumba, komanso amagwiritsidwa ntchito pazinthu zosanyamula katundu, ingathandize kusunga kukhazikika kwa nyumbayo komanso kulimba kutengera phindu lotsika mtengo.
Zindikirani: Zofunikira zonse mu BS EN 10210 zimagwiranso ntchito ku EN 10210 ndipo chifukwa chake sizibwerezedwanso pano.

Kuyambira pomwe idakhazikitsidwa mu 2014,Chitsulo cha Botopwakhala kampani yotsogola yogulitsa mapaipi achitsulo cha kaboni kumpoto kwa China, yodziwika bwino chifukwa cha ntchito zabwino kwambiri, zinthu zapamwamba, komanso mayankho omveka bwino.
Kampaniyo imapereka mapaipi osiyanasiyana achitsulo cha kaboni ndi zinthu zina zokhudzana nazo, kuphatikizapo mapaipi achitsulo opanda msoko, ERW, LSAW, ndi SSAW, komanso mndandanda wathunthu wa zolumikizira mapaipi ndi ma flange. Zogulitsa zake zapadera zimaphatikizaponso zitsulo zapamwamba kwambiri ndi zitsulo zosapanga dzimbiri za austenitic, zopangidwa kuti zikwaniritse zosowa za mapulojekiti osiyanasiyana a mapaipi.
