FAQ
S355JR sib npaug li cas?
S355JR cov qib sib npaug muaj cov tshuaj lom neeg zoo heev thiab cov khoom siv kho tshuab rau cov hlau S355JR. Ob lub S355JR sib npaug qib Q345B, A572 Gr 50, ST52-3, SM490B thiab S355JR steel yog cov khoom tseem ceeb ntawm BBN steel.
Cov yam ntxwv steel qib S355JR yog dab tsi?
S355JR steel muaj lub zog siab - rau - qhov hnyav piv, ua rau nws tsim nyog siv rau hauv kev thauj khoom- cov kabmob xws li txuas hniav, vaj tse, thiab cov qauv sab nrauv. Nws muaj qhov tsawg kawg nkaus lub zog ntawm 355 N / mm², ua rau nws yog ib qho ntawm cov qib steel muaj zog tshaj plaws.
Qhov txawv ntawm S355JR thiab J2 yog dab tsi?
Hauv S355JR thiab S355J2 steel, JR thiab J2 qhia tias cov hlau yuav tsum tau ua +20℃cuam tshuam kev xeem thiab -20℃cuam tshuam kev xeem feem. Qhov sib txawv ntawm qhov kub thiab txias yog qhov sib txawv ntawm S355JR thiab S355J2 steel. S355J2 steel tuaj yeem hloov kho kom haum rau qhov ua haujlwm kub qis dua li S355JR steel.

Tus nqi ntawm S355JR ib kg yog dab tsi?
Mild Steel, Qib: S355JR – 0.61 USD/kg|610 USD / ton
Qhov txawv ntawm S275JR thiab S355JR yog dab tsi?
S275JR yog carbon hlau, thaum S355JR yog cov hlau tsis tshua muaj hlau. Ob leeg carbon steel S275JR thiab S355JR qis alloy steel yog nyob rau hauv EN10025-2 tus qauv. S355JR cov hlau tsis tshua muaj hlau yog qib steel siab dua li cov hlau S275JR.
