S275J2 Cov Roj Carbon Low Carbon Muaj Zog Hlau H Be Be
En 10025-2}: S275J2 H-Shaped Hlau Beam yog European Cov Qauv Hlau Nyob Hauv EN 10025, Tsim los rau load-bearing rau cov tuam tsev thiab tshuab.
Tshuaj Muaj Tshuaj
Cov pa roj carbon (c): tsawg dua los yog sib npaug rau 0. 18% (ua kom zoo rau Weldability thiab lub zog sib npaug).
Manganese (MN): tsawg dua lossis sib npaug rau 1.40-1.50% (txhim kho cov kev nyuaj thiab tensile lub zog).
Phosphorus (p): tsawg dua lossis sib npaug rau {{0}}}}}. 025% (txo qis brittleness).
Sulphur (s): tsawg dua los yog sib npaug rau {{0}}}}}. 025% (tiv thaiv kub tawg thaum chaw tsim khoom).
Tooj liab (CU): tsawg dua los yog sib npaug rau 0. 055% (txhim kho atmospheric corrosion).
Cov Khoom Siv Neeg Kho Tshuab tawm los Lub Zog (Ras
Tensile Lub Zog (RM): 410-580 MPa (balanced lub zog thiab ductility).
Elongation (A5): Ntau dua los yog sib npaug rau 23% (kom ntseeg tau yam tsis muaj kev ntxhov siab).
Kev Cuam Tshuam Cov Khoom Siv: Loj dua lossis sib npaug ntawm 27 I2 {1}}} degree (tseem ceeb rau kev nyab xeeb huab cua txias).
Kev sib piv nrog cov qhab nia zoo sib xws S275J2 H hom nqaj Vs. S275jr H Beam qauv: J2}} degree vs 20 degree cuam tshuam xeem rau jr).
S275J2 H tshooj Hlau vs. S355j2 qauv H nqaj: qis MPA Vs. 355 MPa), tab sis zoo dua raug nqi rau cov ntawv thov tsis yog-tseem ceeb.
