S355J0 thiab S355J2 yog cov txheej txheem steels raws li EN 10025 tus qauv, sib koom qhov tsawg kawg nkaus lub zog ntawm 355 MPa, tab sis lawv qhov sib txawv tseem ceeb nyob rau hauv Charpy qhov ntsuas kub: S355J0 yuav tsum 27 Joules ntawm 0 ° C, thaum S355J2 yuav tsum tau 27 Joules {35J2} ua kom txias dua. rau cov ntawv thov kub qis, nrog me ntsis qis phosphorus / sulfur cov ntsiab lus thiab muaj peev xwm ua kom lub neej qaug zog zoo dua.
S: Cov qauv hlau.
355: Tsawg tshaj tawm lub zog ntawm 355 MPa.
J: Qhia txog Charpy V-qhov ntsuas qhov cuam tshuam.
0 / 2: Qhov ntsuas kub (hauv ° C) ntawm qhov kev ntsuas cuam tshuam (0 ° C rau J0, -20 ° C rau J2).

Qhov txawv tseem ceeb
Impact Test Temperature:
S355J0: Kuaj ntawm 0 ° C (32 ° F).
S355J2: Kuaj ntawm -20 ° C (-4 ° F).
Toughness: S355J2 muaj zog toughness ntawm qis qis, ua rau nws haum rau qhov chaw txias dua.
Chemical Composition (S355J2 vs. S355J0): S355J2 feem ntau muaj qis tshaj qhov txwv rau Phosphorus (P) thiab Sulfur (S) (0.025% vs 0.030%), thiab tsis muaj nitrogen (N) txwv, uas ua rau nws cov kev ua haujlwm txias txias.
