Raws li JIS G3444 tus qauv, STK290 yog qib tshwj xeeb, sib haum rau cov kav dej carbon steel rau cov qauv dav dav. Lub zog tensile σb ntawm STK290 steel kav yuav tsum tsis pub tsawg tshaj 290Mpa.
Cov txheej txheem tsim khoom ntawm STK290 carbon steel kav uas tsim los ntawm GNEE tuaj yeem ua seamless, hluav taws xob tsis kam vuam ERW, submerged arc vuam SAW, thiab lwm yam, nrog rau ntau yam ntawm 15A txog 800A thiab phab ntsa tuab ntawm SCH20 txog SCH160. Tsis tas li ntawd, STK290 hollow steel kav kuj tseem tuaj yeem ua tiav raws li qhov xav tau, xws li cov qauv vuam, 3PE ntawm cov yeeb nkab steel nto, galvanizing, thiab lwm yam.
