S275J2 angle steel and S355J2 angle steel low temperature materials
Source:Xin Steel Industry Date:2021/07/27
Universal beam also Low temperature steel matreials EN 10025-2 specification S275J2 angle steel and S355J2 angle steel shall be done charpy V notch impact test at minus 20 Degree centigrade when supplying.S275J2 angle steel owned minimum yield strength above 275 Mpa and S355J2 angle steel owned minimum yield strength above 355 Mpa which is equal to Q355D angle steel in Chinese specification GB/T 706.Other standard angle steel stock in Xinsteel industrial warehouses including A572 Gr50 angle steel,St52-3 angle steel,St50-2 angle steel,St37 angle steel.
Currently more and more end users choose low temperature angle bars,because S275J2 angle bar and S355J2 angle bar can bear -20℃ temperature after done charp-V notch impact test when rolling.
