S420m s420ml h tshuab hlau
S420m s420ml nqaj hlau
S420m H nqaj ntu yog ib qho thermăchamanically dov weldable nplua qoob ke ntawm cov kab sib tw yob tawm txog li 120 hli tuab.
S420ML is the European standard high strength structural steel, similar to the national standard Q420q, it has good mechanical properties and process performance, high NMenability, adding vanadium to make the steel grain refinement, reduce the sensitivity to overheating, improve the strength and toughness, with high fatigue strength, yield ratio is also higher, but the weldability is poor, and the plasticity of the cold due to deformation is also relatively low.
S420ml neeg kho tshuab: Tshaj tawm lub zog σS (MPA) ntau dua lossis sib npaug ntawm 1300; elongation Δ5 (%) ntau dua los yog sib npaug rau 6; ntu shrinkage ψ (%) ntau dua los yog sib npaug rau 25; Nmness tsawg dua los yog sib npaug rau 321hbw.
S420ml Txheej Txheem Hlau Hlau yog qhov haum rau cov haujlwm hnyav ntawm welded cov qauv siv rau kev siv hauv ambient thiab tsawg-qhov rooj, chaw tso tsheb hlau luam.
