S355J2 angle bar comparasion with S355JR angle steel
Source:Xin Steel Industry Date:2021/03/08
S355J2 angle bar and S355JR angle steel are both very common used in structural industry.Minimum 355 Mpa yield strength and 470Mpa tensile strength for S355J2 and S355JR angle steels.
When S355J2 angle bar comparasion with S355JR angle steel,The main difference is application temperature,S355J2 angle bar done low temperature at -20℃,S355JR angle bar done impacting test only at Room temperture 20℃,So S355J2 angle bar can be used in deep ocean surroudings and other low temperature weathering.S355JR angle steel can not be used in low temperature weathering.
