Cov yam ntxwv tseem ceeb
Txheem: Ob qho tib si poob rau hauv EN 10025-3 rau cov qauv zoo li qub, kom ntseeg tau qhov zoo weldability thiab cuam tshuam toughness.
Lub zog: S460N muaj qhov tsawg kawg nkaus tawm lub zog ntawm 460 MPa, thaum S420N muaj 420 MPa, ua rau S460N muaj zog rau hnyav - daim ntawv thov.
Daim ntaub ntawv: Siv nyob rau hauv loj welded lug, nrog rau cov choj, cranes, fais fab nroj tsuag, boilers, thiab mining machinery.
Weldability: Ob leeg muaj kev sib txuas zoo, feem ntau xav tau preheating thiab tsim nyog consumables (xws li ER70S-6), nrog qis carbon equivalents (CEV) pab fabrication.
Tsawg-Temp Toughness: 'N' qhia txog kev xa khoom ib txwm muaj, muab cov khoom zoo, nrog rau qib 'NL' muab kev ua tau zoo dua ntawm qhov kub qis dua (xws li -50℃vs. S460N's -20 degree) rau cov huab cua txias.
