S355JR+AR hem beam and S355J2+N hem beam steel materials
Source:Steel Industry Date:2021/03/22
S355JR+AR hem beam and S355J2+N hem beam high tensile steel materials supplying comply to european steel specification EN 10025-2.Owned minimum yield strength 355Mpa,S355JR+AR HEM beam and S355J2+N HEAM beam can be used in high tensile strength structural steel frames.S355JR+AR HEM beam normally used in room temperature,but S355J2+N hem beam can used in -20 Deg.Centigrade temperature surroudings.N means normalized heat treatment shall be done for S355J2+N hem beams.If without Normalized treatment,it have to be as steel grade S355J2 HEM beam or S355J2+AR HEM beam.
Many dimension ham beam steel materials are in our stock ready for shipment including
