Q355 steel yog dab tsi
Q355steel khoom Taw qhia
Q355 yog Suav cov qauv steel qib uas piv rau Q345 tab sis muaj lub zog zoo dua. Nws yog qee zaum hu ua Q355B lossis Q355D, raws li nws cov tshuaj pleev ib ce thiab cov khoom siv zoo. Q355 steel yog npaj kom muaj qhov tsawg kawg nkaus lub zog ntawm 355 MPa, uas yog ntau dua li 345 MPa yield zog ntawm Q345 steel.
Q355 steel tau nce kev ua tau zoo thiab feem ntau yog siv rau hauv cov qauv siv uas xav tau ntau zog. Nws yog siv nyob rau hauv kev tsim kho kev lag luam los fabricate beams, kab, thiab lwm yam load- bearing lug. Q355 steel kuj tsim nyog rau kev tsim cov khoom siv, txuas hniav, thiab cov qauv sab nrauv.
Cov qib sib npaug ntawm Q355 steel sib txawv nyob ntawm cov qauv thoob ntiaj teb siv rau kev sib piv. Nov yog qee qhov sib npaug siv feem ntau:
ASTM A572 Gr 50: Qhov no yog qib sib npaug rau Q355 hauv Asmeskas cov qauv ASTM. Nws muaj qhov tsawg kawg nkaus tawm lub zog ntawm 345 MPa thiab feem ntau siv rau hauv cov qauv siv.
S355JR: Qhov no yog qib sib npaug rau Q355 hauv European EN cov qauv. Nws muaj qhov tsawg kawg nkaus lub zog ntawm 355 MPa thiab yog dav siv nyob rau hauv cov qauv thiab engineering daim ntaub ntawv.
SM490B lossis SM490C: Cov no yog cov qib sib npaug rau Q355 hauv Japanese JIS cov qauv. Lawv muaj qhov ua tau zoo tshaj plaws ntawm 325 MPa thiab 365 MPa, feem, thiab feem ntau yog siv rau hauv cov qauv siv.
