Qhia Txog Kev Ua Tau Zoo Tshaj Plaws: 09G2S vs Q355B / Q355D / Q355E :

1.Temperature Adaptability (Qhov tseem ceeb tshaj plaws rau Russia & Central Asia)

Q355B: Tsis muaj qhov ntsuas qhov ntsuas kub qis → tsuas yog rau thaj tsam me me, tsis haum rauSiberia, sab qaum teb Kazakhstan, lub caij ntuj no tej yaam num
Q355D: -20℃cuam tshuam → nruab nrab qhov chaw txias
Q355E: -40℃cuam tshuam → huab cua txias
09G2S: Tsim los ntawm GOST tus qauv rau CIS huab cua txias, kev ua haujlwm ruaj khov ntawm -40℃~ -50 degree, lees paub los ntawm Lavxias teb sab kev tsim kho & cov qauv siv hluav taws xob, kev ua lag luam siab dua li Q355E hauv tebchaws Russia hais lus.

2. Lub zog & Ductility

09G2S yield zog ~ 345MPa, me ntsis qis dua Q355 (355MPa), tab sis tensile lub zog siab dua → zoo dua tsis kam mus rau tam sim ntawd load hloov nyob rau hauv huab cua txias
Elongation tib theem → kev ua haujlwm zoo

3.Weldability & Kev lees txais kev tsim kho

09G2S qis carbon → vuam yooj yim dua, tsawg dua tom qab vuam kev pheej hmoo ntawm kev tsim kho qhov kub thiab txias
Q355E muaj nruj impurity tswj tab sis siab dua carbon → nruj vuam txheej txheem yuav tsum tau
