S275JR Tsawg Alloy Steel

S275jr tsawg-alloy steel: muaj pes tsawg leeg, khoom, thiab cov ntawv thov

Muaj pes tsawg

S275JR yog cov qauv tsis-alloy qauv hlau cais hauv qab European cov qauv en {2}}. Nws cov tshuaj sib xyaw feem ntau muaj:

Cov pa roj carbon (c):Tsawg dua los yog sib npaug rau 0. 21%

Manganese (MN):Tsawg dua los yog sib npaug rau 1.50%

Silicon (si):Tsawg dua los yog sib npaug rau 0. 50%

Phosphorus (p):Tsawg dua lossis sib npaug rau 0. 035%

Sulphur (s):Tsawg dua lossis sib npaug rau 0. 035%

Qhov "JR" qhia qhia tau zoo cuam tshuam ntawm chav tsev kub (tsawg kawg 27 degree), ua rau nws tsim nyog rau welded qauv thiab kev tsim kho dav.                       

Cov Khoom Siv Neeg Kho Tshuab

Yield zog (R):Ntau dua los yog sib npaug rau 275 mpa

Tensile Lub Zog (RM):410-560 MPa

Elongation (AO):Ntau dua los yog sib npaug rau 23% (nyob ntawm cov tuab)

Kev Cuam Tshuam Tougness (KV):Ntau dua los yog sib luag rau 27 j ntawm +20 degree

S275JR muaj kev ua tau zoo heev weldability, formability, thiab contacing, ntsuas lub zog thiab kev ua kom muaj zog rau cov ntawv thov kev tsim qauv.

Cov Ntawv Thov

Vim nws cov txiaj ntsig zoo thiab kev ua tau zoo, S275JR tau siv dav hauv:

Kev Tsim Kho:Cov thav hlau, cov kab teeb, kab, thiab cov qauv txuas ntxiv.

Infrastructure:Txuas hniav, kev hloov cov yees, thiab cov qauv txhawb nqa.

Kev Tsim Dav:Cov tshuab ua haujlwm tshuab, tso tsheb hlau cia cia, thiab khoom siv muaj.

Tsheb thauj mus los:Chassis thiab cov txheej txheem hauv cov tsheb hnyav.

Nws ua raws nrog en 10025-2} saib kom zoo ib yam, ua rau nws xaiv qhov kev xaiv uas zoo tshaj plaws hauv cov chaw nruab nrab.
