S275J 0 Hem Hlau Beob
Vim li cas thiaj xaiv GNEE S275J {1}} h-nqaj?
S275J {0 h hom hlau nqaj qhia tau tsawg kawg ntawm 275 MPa thiab cov ntsiab lus}} degree cuam tshuam. Rau cov phiaj xwm uas xav tau kev txhim khu kev qha cov qauv kev pab txhawb nrog nruab nrab lub zog thiab kub} h-nqaj tsim los ntawm GNEE kev ua tau zoo tshaj plaws. Ua raws li cov qauv hauv European ua kom tau txais txiaj ntsig thoob ntiaj teb thiab muab daim ntawv pov thawj thib peb.
Tshuaj lom neeg muaj pes tsawg leeg ntawm S275J 0 qauv hlau steel nqaj ua kom zoo tshaj plaws thiab durability:
Cov pa roj carbon (c): tsawg dua lossis sib npaug rau 0. 22%
Manganese (MN): Tsawg dua lossis sib npaug rau 1.50%
Phosphorus (p): tsawg dua lossis sib npaug rau 0. 035%
Sulphur (s): Tsawg dua lossis sib npaug rau 0. 035%
Nitrogen (n): tsawg dua lossis sib npaug rau 0. 009%
Silicon (si): tsawg dua lossis sib npaug rau 0. 40% (qhov twg teev)
Carbon sib npaug Tus nqi (CEV): tsawg dua lossis sib npaug nrog 0. 41% rau thickness tsawg dua los yog sib npaug rau 16 hli.
Cov khoom tseem ceeb ntawm S275J {1}} h bar seem muaj:
Paib lub zog (rov qab):
275 MPa (tuab tsawg dua los yog sib npaug rau 16 hli)
26PA (16-40MM)
255 MPa (40-63mm)
245 MPa (63-80mm)
235 MPa (80-100mm)
225 MPa (100-120mm)
Tensile Lub Zog (RM):
410-560 MPa (tsawg dua los yog sib npaug rau 16 hli) rau 400-540 MPa (100-120mm).
Elongation (a): ntau dua lossis sib npaug rau 23% (tsawg dua lossis sib npaug rau 40mm) rau ntau dua lossis sib npaug rau 19% (100-120mm).
Kev Cuam Tshuam Lub Zog (KV): Ntau dua lossis sib npaug rau 27 J ntawm 0 degree (men deg degree (mench nyuaj).
S275J {0 h steel profile yog siv dav hauv:
Kev tsim kho: High-nce vaj tse, txuas hniav thiab muaj cov thav ntawv.
Tsheb Thauj Mus Los: Kev Railway Systems, Shipbuilding Thiab Qhov Automotive.
Machinery: Cov cuab yeej hnyav, cranes thiab siab cov hlab ntsha.
Zog: Cov nroj tsuag fais fab, cua tshuab cua thiab roj / roj av infrastructure.
