Khoom Description
Qauv Q355 Lub kaum sab xis hlau yog cov hlau tsis tshua muaj siab lub zog steel feem ntau siv hauv Suav teb, uas hloov Q345. Cov khoom siv muaj qhov tsawg kawg nkaus lub zog ntawm 355 MPa (51 ksi) thiab lub zog tensile ntawm 470-630 Mpa (68-91 ksi). Lub kaum sab xis steel yog ib hom carbon structural steel rau lub tsev. Nws yog ib yam yooj yim seem steel. Nws yog tsuas yog siv rau cov tswv cuab hlau thiab cov ncej ntawm kev cob qhia. Zoo solderability, yas deformation cov cuab yeej thiab tej yam mechanical zog yuav tsum tau siv nyob rau hauv kev siv. Cov khoom siv raw rau kev tsim lub kaum sab xis steel yog qis carbon square billet, thiab lub kaum sab xis tiav yog xa hauv kub dov, normalizing lossis kub dov lub xeev.
