S355NL Material

S355NL material is a normalizing steel (fine grain steel) in the EN10025-3: 2004 standard. EN S355NL normalized steel is produced by heating the steel to a temperature above the critical temperature, so that all the steel is transformed into uniform austenite, and then naturally cooled in the air. Its yield strength and tensile strength correspond to China's Q345 low-alloy steel. NL is required to perform an impact absorption work test in a low temperature environment of minus 50 degrees, and the impact value is not less than 27J.

14MnNbq normalized steel butt submerged arc welding with a thickness of 16 to 32 mm. The welds welded with H08Mn2E + SJ101q are visually inspected, ultrasonic, ray inspection and mechanical performance tests. The mechanical properties of the welded joints can meet the 32 m composite beam of the Qinghai-Tibet Railway Technical requirements.
