High tensile S355JR channel steel and S355J2 channel steel
Source:Xin Steel Industry Date:2021/08/24
High tensile S355JR channel steel and S355J2 channel steel both owned minimum yield strength at 355 mpa and tensile strength within 470-630 Mpa,S355J2 channel steel shall be done low temperature impact test at -20 ℃,however S355JR done impact test at room temperature or no need.So S355J2 channel steel perfer to use in low temperature surroudings which called as low temperature high strength channel steel.
ABS certificate S355J2 channel steel and S355JR channel steel stock in our warehouse with various dimensions in EN 10204 3.2 mill certificate.Other third inspection party includes BV,DNV-GL,CCS,TUV,LR,SGS also can be done for our stock steel materials.
